Phytochemical Analysis Revealing the Presence of Two New Compounds from the Latex of Calotropis Procera (Ait.) R.Br.

Calotropis procera (Ait.) R.Br. (Asclepiadaceae) is a well known Indian medicinal plant. Its latex constituents having high calorific value because of its rich hydrocarbons. Moreover it was traditionally applied for tanninizing leather in India. Several attempts have been made in the past to establish it as a biofuel crop. In the present study the major phyto-constituents from the dried latex of C. procera are identified through GC-MS analysis. Acetone extract derived from the dried latex of C. procera was further partitioned between n-hexane and ethanol (10:90). The n-hexane layer was separated, dried and re-dissolved in Acetone. The un-dissolved part was dissolved in n-Hexane:Methanol (9:1) combination. Both the fractions were subjected for GC-MS analysis and nine hydrocarbon compounds have been identified from the latex, out of which 2,6 dimethyl tetra-1,5-decaene and 3, 7,11-Trimethyl-2,6,10,12-pentadecatrien-1-ol are newly reported from latex of C. procera.
