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. &lt;strong&gt;Methods:&lt;/strong&gt; 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. &lt;strong&gt;Result:&lt;/strong&gt; 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 &lt;em&gt;Sarcostemma viminale&lt;/em&gt; (L.) R.Br. &lt;strong&gt;Conclusion:&lt;/strong&gt; Flowers of &lt;em&gt;Sarcostemma viminale&lt;/em&gt; (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.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue><work-type><style face="normal" font="default" size="100%">Original Article</style></work-type><section><style face="normal" font="default" size="100%">871</style></section><auth-address><style face="normal" font="default" size="100%">&lt;p&gt;&lt;strong&gt;Sunita Arora&lt;sup&gt;1*&lt;/sup&gt;&amp;nbsp;and&amp;nbsp;Sonam Meena&lt;sup&gt;2 &lt;/sup&gt;&lt;/strong&gt;&lt;/p&gt;
