Standardization and GC-MS Analysis of Phytochemicals in Coccinia indica (Wight and Arn.) Fruits

Background

Coccinia indica, commonly known as the ivy gourd, is traditionally utilized for its diverse medicinal properties.

Objectives

The objectives of the study were to standardize and evaluate the fruits of Coccinia indica by identifying the phytochemicals using GC-MS analysis.

Materials and Methods

Standard methodologies were used for the standardization, including macroscopical, microscopical, physico-chemical evaluations and phytochemical screening. Additionally, GC-MS analysis was performed to identify key components in the plant extract and its fractions.

Results

The T.S. of the fruits of C. indica showed a single epicarp, mesocarp and several fibro-vascular bundles, while the T.S. of the seed revealed the presence of a testa, tegmen, embryo, starch grains and several oil globules. The main findings were as follows: total ash 16.52±0.13% w/w, water-soluble ash 11.35±0.12% w/w, acid-insoluble ash 1.45±0.06% w/w, water-soluble extractive value 18.45±0.2% w/w, alcohol-soluble extractive value 8.80±0.11% w/w, moisture content 7.33±0.08% w/w and the pH of the aqueous extract was 5.63±0.07 (1% w/v) and 5.79±0.09 (10% w/v). Phytochemical investigation revealed the presence of alkaloids, steroids, flavonoids, saponins, tannins, phenolics and terpenoids. GC-MS analysis identified more than forty notable chemicals in the methanol extract and fractions of chloroform and hexane.

Conclusion

This study provides key insights into the standardization of C. indica fruits and identifies 43 major secondary metabolites through GC-MS analysis. Notable compounds include taraxerone, squalene, lupeol and piperine, all with potential therapeutic benefits. Moreover, the choice of solvent for extraction and fractionation significantly influenced the phytochemical profile and concentrations.
