Abstract

39 cultivars of ginkgo nuts were used to detect the content of ginkgotoxin, and were divided into 4 cultivar groups, including the main nut cultivars in China. The results showed that there was no significant correlation between different cultivars and ginkgotoxin content, however, there were significant differences between the 4 cultivar groups (P<0.05). The ginkgotoxin content of 39 ginkgo cultivars ranged from 330.25 μg∙g-1 to 525.79 μg∙g-1. MPN accounts for most of the ginkgotoxin, from 54% to 95%. The ginkgotoxin content of 4 cultivar groups was ranked as Changzi, Fozhi, Zhongzi, Yuanzi. The correlation between ginkgotoxin and different cultivar groups was explored for the first time. Based on this finding, people can preliminarily determine the level of ginkgotoxin, which provides help and convenience for daily consumption.
