文摘内容 Total contents and components of escin were studied in seeds of Aesculus chinensis, A. chinensis var. chekiangensis and A. wilsonii collected from 8 origins. Results showed that total escin content ranged from 71.43 mg-g to 112.69 mg'g , with the highest in origin of Mabian, Sichuan Province and the lowest in origin of Kangxian, Gansu Province. It was suggested that escin content was correlated with geological zone to a certain extent. A. wilsonii was richer than that of Aescu!us chinernis in escin content. The proportion of 4 types of escin varied dramatically among different origins. Component A in Mabian and Cangwang origin from Sichuan Province, Kangxian origin from Gansu Province, Mianxian origin from Shanxi Provifice and Xixia origin from Henan Province reached 35%-41% of total escin that was much higher than that of other components, while components D was below 15% that was only 1/3 of component A. Sum of Component A and C was nearly equal in Enshi, Hubei Province and Sangzhi, Hunan Province origins, which accounted for 58 % of the total content. Lin' an origins from Zhejiang Province only got 17.17% of component A while holding much higher proportion of component D. Statistical analysis also approved that the proportion of escin was correlated to geological zone。
