FATTY ACID PROFILING IN DIPLOID (n = 12) AND TETRAPLOID CYTOTYPES (n = 24) OF PHYSALIS ANGULATA LINN. FROM RAJASTHAN BY GAS CHROMATOGRAPHYAbstract
Present paper reports the chemical constituents in the fatty acids obtained from the whole plant of diploid and tetraploid Physalis angulata Linn. collected from hot desert areas of Rajasthan. The fatty acid analysis was carried out by gas chromatography-flame ionization detector (GC-FID). Meiotic studies confirm the ploidy level of the plant. Diploid (n = 12) cytotype is reported from Udaipur district and tetraploid (n = 24) cytotype from Sri Ganganagar. There is a considerable difference in the fatty acid constituents in the cytotypes. Major constituents of fatty acids are Oleic acid (24.93%, 2x; 18.71%, 4x); capric acid (13.4%, 2x; 0.14%, 4x); Palmitic acid (6.966%, 2x; 12.38%, 4x); Linoleic acid (5.5%, 2x; 9.76%, 4x) and Linolenic acid (6%, 2x; 11.67%, 4x). The main objective of the object work was to compare the fatty acid composition within two cytotypes. Such analysis of plants is very important on commercial level for the productions of cosmetic and has great interest in pharmaceutical companies for the production of drugs.
