Dendrophthoe Petandra L. Miq.s Progesterone-Like Effect

Dendrophthoe Petandra L. Miq.s Progesterone-Like Effect ABSTRACT The in-vivo study on healthy adult female rat were known that extract methanol of Dendrophthoe Petandra L. Miq by intramuscular injection (w/v) at dose 100 mg/kg body weight for four days (s.d.d.) can be produce progesterone hormone two times more than usual levels. That phenomenon apparently indicates that plant as an Indonesia namely Benalu duku were probably consist of steroid with carbon bonding substances at number 1st to 21st namely pregnane derivate. These research aims to determined specificity active substances of methanol crude extract Benalu duku leaves with pharmacodynamics effect like progesterone hormone. Pulverized Benalu duku leaves at 400g was extracted with 2 L methanol pro analysis grade by shaker maceration method at 200C during the 72 hours. Semi solid crude extract were drying by vacuum dried apparatus and UV exposure at 15 minutes and analysis by FT-IR and LC ESI MS. Research result obtained that active substances with main chemical structure of pregnane deriva te were progesterone at about 30%, medroxy progesterone acetate at about 66%, megestrol acetate at about 3% and 1% dydrogesterone. Key words: Benalu duku, pregnane derivate, anabolic steroid, leaves extract FT-IR, Methanolic leaves extract LC-ESI MS. Introduction Dendrophtoe Petandra L Miq (Benalu duku) as a parasites plant growing on Lancium demesticum were known have a several essential active substances and useful for treated proliferation cell (NURAINI et al., 2000, ROOSTANTIA et al., 2000 and RATNA et al., 2007). Some researcher reported that plants have a beneficially active substance like alkaloid, flavonoid, polyphenol, terpenoid and free steroid (ARIFA et al., 2009). New research report explained that crude methanolic extract of Benalu duku leaves can be increasing progesterone hormone two times more than usual levels, but giving FSH levels on female adult rat (BAMBANG, LAZUARDI, 2014). The last research report indicate that plants have a several substances with characterize as a progesterone like effect. Characterization progesterone like effect was known have a specific chemical main structure namely pregnane derivate with consist of carbon at 1st to 21st at their double bonded chain structure or (8S,9S,10S,13R,14S,17S)-17-ethyl- 10,13-dimethyl-2,3,4,5,6,7,8,9,11,12, 14,15,16,17-tetradecahydro-1H- cyclopenta [a] phenanthrene. Identically of their main structure of pregnane derivate were known as an anabolic hormone and usefully for treatment prostate cancer in adult man (RANDOX LABORATORY LTD, 2013). Pregnane derivate were known have some specific anabolic steroid structure i.e cortisone, hydrocortisone, progesterone, medroxy progesterone acetate, megestrol acetate, 17- ÃŽ ±- hydroxyl progesterone acetate, dydrogesterone. Other herbal medicine with anabolic steroid action was found at Mexico namely Codices plant. That plant was similar with Benalu duku as a parasites plant growing at subtropics seasons (LERNER, ARNWINE, 2002). With analog to Codices plant in Mexico, might be benalu duku leaves after extracted by methanol were containing specific anabolic steroid. By background research at above, will be determined progesterone like effect substance like progesterone, medroxy progesterone acetate, megestrol acetate, dydrogesterone from base on overview of identic molecule ion of LC-ESI MS and function compound of FT-IR. Materials and methods Benalu duku leaves were obtained from Muara Enim region of west Sumatera-Indonesia and identification as a Dendrophthoe Petandra L. Miq at Botany Research Institute at Tangerang – Jakarta Indonesia as described by BAMBANG, LAZUARDI (2014). Reference substance of progesterone was obtained from Sigma-aldrich product 46665 batch SEBA XV. Reference substance of medroxy progesterone acetate was obtained from Harsen pharmaceutical Industry Jakarta – Indonesia at pharmaceutics grade. Megestrol acetate reference material was obtained from Sigma Aldrich at product 46420 batch SZB9173XV. Dydrogesterone reference material was used from European Directorate for quality medicines and health care, France by catalog code Y0001004. A 400 gram of pulverize benalu duku leaves were extracted on 2 L of methanol pro analysis on to the 1 L separated flask during the 72 hours (movement shaker maceration method at 200C). The semi-solid of crude extract were dried on vacum drying and exposure to uv light (15 minutes) for kept contaminate from the mold and some bacteria. Some amount of semi-solid crude extract benalu duku leaves was determined specific molecule structure compound by FT –IR PerkinElmer Frontier 89485 and LC-ESI MS Accela TSQ Quantum Acess Thermo. The semi-solid crude extract methanol of benalu duku leaves was determined to molecule function of progesterone like effect substances at 400 cm-1 to 4000 cm-1 . Performance control of LC-ESI MS were adjusted as follows; column hypersil Gold 0.2  µm length 10 cm gradient method with mobile phase at bottle A 0.1% in Aqua bidest and bottle B 0,1% formic acid in acetonitrile pro HPLC. The gradient was perform at 35% to70% of B in 20 minute at 254 nm UV detector. Automatic sucking and injection capacity was adjusted at 10  µl, flushing capacity 400  µl with velocity at 100 µl.second-1, velocity injector 8  µl.second-1, height of suction apparatus at about 2 ml capacity autosample vial at 1.2 ml. Temperature column was adjusted at 220C at maximum pressure pump 1250 PSI and stabile in 10 BAR (THERMO ELECTRON CORPORATION, 2007). Results Analysis Spectrum infra-red of crude extract methanol Benalu duku leaves obtained that stretching aromatic compound specific overtone was presented at 1650 to 2000 cm-1. Especial in 1550 cm-1 to 1600 cm-1 was appeared stretching aromatic compound (1,s). In 1450 cm-1 to 1500 cm-1 was appeared s orbital of stretching aromatic compounds. At finger print area wavelength number of 600 cm-1 to 900 cm-1 and 1000 cm-1 to 1300 cm-1 were indicate of flexible carbon atom and hydrogen outside of area (k orbital) and inside of area (l orbital).

Discussion Analysis by retention time and ESI (m/z) of LC ESI-MS were apparently just two of progesterone like effect substances on crude extract methanol benalu duku leaves that very identic substances to reference material namely medroxy progesterone acetate and progesterone. Other progesterone like effect substances as a megestrol acetate and dydrogesterone on crude extract methanol benalu duku leaves were mostly identic to reference material of megestrol acetate and dydrogesterone by different shift at 0.01 and 0.6 retention time of reference materials. Difference in retention time shift is closely linked nature of polarity samples bound to the column Hypersil Gold of LC. Thus the most likely molecular structure of megestrol acetate and dydrogesterone on methanol extract of benalu duku no resemblance to 100% identically as reference materials of megestrol acetate and dydrogesterone. Analysis to compare between the values of molecule ion fragments (m/z) and ESI (m/z) reference materials of f ourth progesterone like effect substances versus identically substances of progesterone like effect on crude extract methanol benalu duku leaves were apparently have a differences values (p

Postcolonial Indian Literature in English: Narayan, Jhabvala, Rushdie :: Essays Papers

Postcolonial Indian Literature in English: Narayan, Jhabvala, Rushdie Indian literature in English which is accessible to us in the West, still has its roots in colonial literature and the tensions between East and West. A European naturalism is often present; a concern to posit India as an arena within which Western readers can identify realities is inherent within much of this writing. The following are three examples of the progression of post-Independence literature. Twenty years after Independence, R.K.Narayan was still tackling issues of colonialism. The Vendor of Sweets (1967) takes us through the tensions integral to a family in which two generations belong to two different cultures. Ascetic Jagan belongs to an old India of family and history ;his son to an India increasingly subject to the foregrounding of the commodity and a dramatic industrialisation. Narayan explores the inevitable clash of what is, in many ways, both a colonial and a post-colonial encounter: Jagan, a follower of Gandhi and a veteran of the wars against British Imperialism, must attempt a negotiation of an ethos invasive to his own definitions of nationality; Mali, without this structure, must reconcile an American capitalism with India's own sense of what constitutes a modern nation. This theme is continued in Ruth Prawer Jhabvala's Heat and Dust (1975). Again two generations, this time British, must come to terms with an alien culture. Whilst Olivia's adventures are romanticised, Jhabvala attempts to explore in a more sophisticated manner the social outlay of Anglo-Indian relations with the higher Muslim classes and Olivia's step-grand-daughter is confronted with an India that remains hidden in the works of Kipling, Forster or Narayan. Leelavati the beggar-woman's life, if not her behaviour, demonstrates an unusual social awareness of the lowest castes. It is to be noted that the East-West dichotomy within the later generation has become less strained: modern Britain is expected now to accept India on its own terms. Salman Rushdie, whose work has been produced in the eighties and nineties, has removed himself from the sites of both nationality and naturalism but remains in an engagement with economic colonialism and its consequences.

A Clockwork Orange: Summary

Synopsis: Young Alex and his gang members (Dim, Pete and Georgie) go on a rampage around the futuristic city in London. In the book what we call evil is actually a form of art to Alex. Alex loves art itself, particularly classical music. To Alex, the delight he finds in classical music is closely related to the joy he feels during acts of violence. The State’s destruction of Alex’s ability to make his own moral choices represents a greater evil than any of Alex’s crimes, since turning Alex into an automaton ultimately sanctions the notion that human nature is dispensable. Alex truly grows as a human being only in the last chapter, after the government removes his conditioning and he can see the error of his ways for himself, without the prompting of an external, controlling force. The slang used by the â€Å"Droogs† represents the social gap between youth and the elders of society. Aspects: Music: Music in this book is one of the main aspects. Music affects everyone in a different way. Alex when he listens to symphonies especially Ludwig Van Beethoven, he gets stimulated to do more violence. Good is bad and bad is good: A regular teens would go to school and have a part time job to make money. As we would think school, having a job, working for yourself is good for you. In a Clockwork Orange everything is switched around. Basically what the young adults find good is like robbing stores, raping women on the street, having gang fights, the good old ultra violence. Satire: The dystopia of  A Clockwork Orange  has a very satirical tone. The aspect of satire in the novel is in the form of political commentary. Alex and his gang deprive the community of moral choice and free will, limiting their personal freedoms. In this way, Anthony Burgess conveys an anti-totalitarian message in the novel. The futuristic dystopian society of the novel is a completely exaggerated claim of what a totalitarian government would lead to. In an attempt to prove the point that a deprivation of personal freedoms would be catastrophic to the world, Burgess paints a picture with absolutely no happiness, a picture painted satirically. Theme: If personal freedom is a justifiable sacrifice for comfort and social stability. His treatment shows that government would rather have a faceless society that shuns emotion and motive. Maturity: When Alex in the end shows that he wants too mature into an adult when he confronts or meets Pete.

Resurgence of Conservatism - 1211 Words

DBQ 15: The Resurgence of Conservatism, 1964-2005 Liberals had dominated American society for most of the 1900s. The 1960s was widely known for being the age of counterculture, social reforms, and liberals. The era witnessed many advancements like racial equality such as the Voting Rights Act of 1965, a strong advancement in political liberalism, and a significant increase in the power and influence of government-funded social programs as a result of Lyndon B.
