Lc-MS/MS and Gc-MS Profiling and the Antioxidant Activity of Carissa Carandas Linn. Fruit Extracts

Abstract

Objective: The present study was carried out with three varieties (green, pink, and sweet) of Carissa carandas fruit extract for the identification of phytochemical constituents in C. carandas fruit extracts using Liquid Chromatography-Mass Spectrometry (LC-MS/MS) and Gas Chromatography-Mass Spectrometry (GCMS) Methods: LC MS/MS and GCMS analysis were adopted to study three varieties of C. carandas fruit, namely green, pink, and sweet, using different solvent extractions such as ethanol, methanol, and aqueous. Results: High levels of phenolic acids and flavonoids in the green variety were beneficial for anti-diabetic activity due to their antioxidant properties. Among the three varieties of tested samples, the maximum concentration was observed in the ethanol extract of the green varieties (2.485 mg/g FW) compared to the ethanol extract of the pink (1.564 mg/g FW) and sweet (1.285 mg/g) varieties, respectively. Ethanol extract of the green variety has a high level of anthocyanin, which increases tolerance to disease. The separation and identification of fatty acids in C. carandas fruit were determined through analysis. The sweet C. carandas variety recorded the highest concentration of fatty acids (147.2 mg/100g FW) compared to the pink and green varieties (94.9 mg/100 g FW) and (72.79 mg/100 g FW), respectively, and could successfully identify the number of phytonutrients that have health benefits. Further work is being carried out, which may lead to the development of herbal medicine. Conclusion: The present study concludes that phytochemicals present in C. carandas fruit, extracted by LC-MS and GC MS analysis, contain antioxidant and anti-diabetic effects.
