摘要

Medicinal plants have been commonly used in traditional medicine for many centuries to cure various ailments because of their phytocompounds, especially the secondary metabolites. Capparis zeylanica Linn., plant of family Capparaceae is used in ‘Rasayana’ of Ayurvedic medicines to cure indigestion and as an antidote to snake bites and to treat inflammation of testicles, smallpox, boils, cholera, colic, hemiplegia, neuralgia, sores, pneumonia and pleurisy. Many studies have indicated that different parts of Capparis zeylanica, which are stem, roots, seeds, and fruit, have many activities, such as antioxidant, anticancer, antiparasitic, antimicrobial, etc. However, there is a lack of exploration of the flower of Capparis zeylanica. Thus, the aim of this study is to identify the phytochemistry and some pharmacological properties of the Capparis zeylanica flower. The qualitative screening of flower methanolic extract revealed the phytochemical compounds such as flavonoids, saponins, terpenoids, anthraquinones, steroids, phlobatannins and carbohydrates, and the total polyphenol content had been exhibited as 79.70 mg GAE/g of dry extract, and the surface functional groups are identified by FTIR. A total of 27 compounds were obtained from the GC-MS/MS analysis, and 61 metabolites were obtained tentatively belonging to the categories of flavonoids, coumarins, carboxylic acids, herbicides, glycosides, alkaloids, terpenoids, antibiotics, fatty acids, carbohydrates, amino acids, phenols, aldehydes, and esters by LC-ESI-QTOF-MS/MS analysis. The antioxidant activity of the flower methanolic extract showed an IC50 value of 57.87 µg mL⁻¹, and the antivibriocidal activity revealed the minimum inhibitory concentration of 62.5 µg mL⁻¹ of the flower methanolic extract against V. parahaemolyticus and V. harveyi. Therefore, the present study revealed the importance of various analytical methods in the determination of the phytochemistry of the flower Capparis zeylanica.
