摘要

Carissa carandas is valued for its nutritional and medicinal properties, yet comprehensive comparative profiling of its different plant parts and types remains limited. The current study aimed to present a comprehensive analysis of the physicochemical, phytochemical, and volatile profiles of various plant parts (fruits, leaves, barks, and roots) from two types of Carissa carandas (i.e., pink and green). The study included collection of plant materials and quantification of sugars, ascorbic acid, total flavonoids, polyphenols, tannins, and antioxidant properties along with Fourier Transform Infrared (FT-IR) spectroscopy for functional group identification, and Gas Chromatography-Mass Spectrometry (GC–MS/MS) for volatile compound profiling. Phytochemical evaluation revealed that pink-type fruits contained the highest ascorbic acid content, whereas leaves were richest in total flavonoids, polyphenols, and tannins. Antioxidant assays (DPPH, FRAP, ABTS, and RPA) demonstrated that leaves possessed superior antioxidant potential, correlating strongly with their phenolic and flavonoid concentrations. FT-IR identified diverse functional groups, indicating that green-type tissues have higher hydrocarbon signatures, while pink-type tissues exhibit greater aromatic characteristics. GC–MS/MS volatile profiling detected 31 compounds, predominantly hydrocarbons, with significant contributions from triterpenes and phthalates. Multivariate analyses further delineate the interrelationships among the parameters studied. These findings provided novel insights into the tissue-specific distribution of nutrients and bioactives in C. carandas, supporting its potential use in functional foods and nutraceuticals.
