Anthocyanin content was measured according to the method of Ranganna. 15 Litchi pericarp tissue (10 g) from 10 fruits wasfinely chopped and extracted with 200 ml HCl – ethanol (1 ml HCl in 99 ml 95% ethanol) at 5 O C for 24 h. The extractwas filtered, diluted, and its absorbance was measured at 530 nm using a spectrophotometer (Thermo Spectronic). Anthocyanin content was expressed as mg per 100 g fresh weight
