Content Differences in Capsaicinoids and Vitamin C of Peppers Cultivated under Different Geographical Environments in Sichuan Province

In order to analyze the content differences of capsaicinoids and vitamin C in peppers cultivated under different geographical environments, we planted two line pepper cultivars and a cow-horn pepper cultivar in Chengdu plain and Panxi plateau according to local planting habit, and then determined the contents of capsaicin, vitamin C and dihydrocapsaicin of their ripe fruits. The results showed that, the contents of capsaicinoids in peppers from Panzhihua and Xichang were significantly lower than those from Chengdu and Suining, but the vitamin C contents were significantly higher in Panzhihua and Xichang. Environment factors affected the contents of capsaicinoids and vitamin C in the three pepper cultivars.
