Background: Sarcostemma viminale (L.) R.Br. (Asclepiadaceae), an endangered medicinal plant distributed in various habitats in semi-arid region of Thar Desert of Rajasthan. Present study is focused on the extraction of bioactive compounds from the flowers of this plant by Gas chromatography mass spectrometry (GC-MS) using Methanol and chloroform as solvents. Methods: Flowers were collected from hilly and stony regions from xeric and harsh conditions of Indian Thar Desert of Rajasthan, during the month of July-September. The phytochemical compounds were investigated using Perkin-Elmer gas chromatography-mass spectrometry, while the mass spectra of the compounds found in the extract were matched with the National Institute of Standards and Technology library. Result: Maximum \% area is found for 24-Norursa-3, 12-diene is present in maximum amount (26.25\%) with retention time (RT) =39.441 min, followed by Tetracontane (20.68\%) with RT=30.275min in the methanolic extract. Lup-20(29)-en-3-ol, acetate, (3.beta.)- is present in maximum amount (35.70\%) with retention time (RT) =38.569 min, followed by Tetracontane (15.24\%) with RT=29.678 min in the chloroform extract of flowers of Sarcostemma viminale (L.) R.Br. Conclusion: Flowers of Sarcostemma viminale (L.) R.Br. shows important pinpoint pharmacological activity. These bio-active constituents can be used by pharmaceutical or other drug designing industry to find a novel drug and pharmacologically active constituents justifying the use of this plant to treat many ailments.

Introduction: Melaleuca alternifolia also known as Tea tree oil belonging to family Myrtaceae. This plant has diverse and therapeutic uses in traditional herbal medicine for treating Skin care, First Aid, Household Cleaning, Hair care, Aromatherapy, Feminine care, Chronic illness, and Dental care in Australia.\ Method: The methanolic extract of Melaleuca alternifolia family Myrtaceae was subjected for Soxhlet extraction in round bottomed flask with petroleum ether. The petroleum ether extracted leaf powder was dried and once again subjected to Soxhlet extraction successively with different solvents viz, chloroform, ethyl acetate and methanol. Result: The IR spectra showed characteristic absorption bands at 3421 cm-1 indicating the presence of a OH group, at 1691cm-1 for C=O group, 2848 cm-1. The 1HNMR spectra showed a triplet signal at \δ 10.44, 9.48, 13.21 showing the presence of OH group and Carboxylic acid. The 13C NMR spectra showed signals at \δ 16.28 for a methyl carbon, \δ 29.89 for a methylene carbon, The ESI-negative mode mass spectrum showed pseudo molecular ions at m/z 515 for [M+] ion. Conclusion: Based on spectral analysis and comparison of the spectral data with literature values, the compounds were identified as 3,3\’dimethylellagic acid and its aglycone portion with some little impurity.
