AI Article Synopsis
- Tocklai vegetative (TV) cultivars are widely grown in Northeast India, and this study examines how seasons affect their total polyphenol (TP) content and antioxidant activity.
- The TP content peaks during the monsoon season, ranging from 230.57 to 283.53 mg g, while lower levels are found in pre-monsoon and autumn.
- A strong positive correlation (R = 0.83-0.96) exists between TP content and antioxidant activity, indicating that higher TP levels lead to better antioxidant performance, particularly during the monsoon.
Article Abstract
Tocklai vegetative (TV) cultivars are extensively planted in the tea-growing regions of Northeast India. The present investigation explores the impact of season on the total polyphenol (TP) content and the antioxidant activity of thirty-one TV cultivars (TV1-TV31) and four other commercially popular cultivars, namely, Betjan, Kharijan, S.3A/3, and T.3E/3. The TP content of the cultivars was observed to be highest in the monsoon season, with values ranging from 230.57 to 283.53 mg g. In the pre-monsoon season and autumn, the TP content ranged from 197.87 to 256.77 mg g and from 169.97 to 223.50 mg g, respectively. Antioxidant activity was measured through DPPH, ABTS, FRAP, and lipid peroxidation inhibition assays. The cultivars showed the highest antioxidant activity in the monsoon in tandem with TP content. A bivariate correlation indicated a highly significant ( ≤ 0.01) positive correlation of antioxidant activity with TP content (R = 0.83-0.96).
