PHYTOCHEMICAL SCREENING AND COMPARATIVE ASSESSMENT OF ANTI-OXIDANT, AMYLASE AND ANTICOAGULANT ACTIVITY OF DIFFERENT PARTS OF COLOCASIA ESCULENTA (L.) SCHOTT

Abstract

The present study focused on the phytochemical analysis and biological activity of corm, leaf and petiole of the plant, C.
esculenta. Phytochemical screening of extracts of edible parts was carried out by GC-HRMS which revealed the presence
of steroids, terpenoids, terpenes, phenols, flavonoids and alkaloids as secondary metabolites. Biological activity of C.
esculenta was evaluated in terms of antioxidant property, α-amylase inhibition activity and anticoagulation ability of
different concentrations of water as well as ethanolic extract. Plant parts showed an excellent antioxidant property,
highest amylase inhibition activity of 92.9% and maximum prothrombin time 22.21 min. This study reveals that natural
plants can be used as the best alternatives to synthetic medicines. C. esculenta can be a natural resource for food and
pharmaceutical industries.
