Studies on the Chemical Constituents of Lysimachia capillipes Hemsl

Eight compounds were isolated from the ethanolic extracts of Lysimachia capillipes Hemsl. They were identified as capilliplactone 1,capillipnin 2,β-daucosterol 3,succinic acid 4, quercetin 5, 3',4',5,5',7-pentahydroxyflavone 6,quercetin-3-O-β-D-glucopyranoside 7 and kaempferol 8 on the basis of chemical and spectral methods. Among them, 1 and 2 were new, their structures were established as all-cis-5-deoxy-pentonic acid-y-lactone and 1,2,4,5-tetrahydroxy-3-n-pentyIbenzen-2,4-di-0-β-D-glucopyranoside through their spectral data (¹HNMR, ¹³CNMR, DEPT, ¹H-¹H COSY, H¹-¹³C COSY, HMBC etc).
