Extraction and isolation of important bioactive compounds from the fruit of Physalis ixocarpa.

The current study investigates pharmaceutically important bioactive compounds in the fruits of Physalis ixocarpa. Two different extractions methods were used to study its effect on percent extract yield, recovery of bioactive compounds and antioxidant activity of the extracts. The data indicated that Soxhlet extraction had high efficiency of recovery than maceration method for extracting compounds; percent extract yield and antioxidant activity of the extracts. In maceration, the percent extract yield was found to be in order of water >methanol >ethyl acetate whereas in Soxhlet extraction, it was in order of methanol >water >ethyl acetate. Ethyl acetate extract produced by Soxhlet extraction showed strong antioxidant activity of 59.7% (250ppm) as compared to other extracts. Analysis of ethyl acetate extract showed the presence of Triglyceride. GC-MS study of triglyceride revealed the presence of trilinoleinic acid (9,12-Octadecdienoic acid), tripalmitin (hexadecanoic acid) and trioleinic acid (9-Octa decenoic acid). Four impure and three pure compounds were isolated from crude methanol extract of the fruit. The structure of pure compounds were identified by NMR and characterized as sugar, glucose and fructose.
