The determination of vitamin C, total phenol and antioxidant activity of some commonly cooking spices crops used in West Bengal

摘要

In the present study, vitamin C, total phenols and antioxidant activity of some common cooking spices crops used in West Bengal were analyzed. Ten (10) spices (onion, chilli, garlic, ginger, turmeric, mustard seed, cumin seed, clove, cardamom and cassia leaf) were selected in order to determine the concentration of ascorbic acid (AA), total phenol (TP) and antioxidant activity as DPPH radical scavenging activity (DPPHRAC). The results obtained show that the values of different variables varied from 5.55 to 0.08 mg g-1 (AA), 21.55 to 7.67 GAE mg g-1 (TP) and 0.18 to 5.99 IC50 value: mg ml-1 (DPPHRAC), respectively. There were negative correlations between TPC and IC50 value of DPPHRAC.
