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.
Tea ( L.) leaves undergo complex chemical transformations during black tea processing. However, the dynamic chemical changes during tea processing have not been explored in popular cultivars of North East India.
