The ether-soluble neutral constituents of the dried roots of Trichosanthes japonica REGEL, Trichosanthes kirilowii MAXIM. and Trichosanthes cucumeroides MAXIM. were examined. Mixed glycerides, Δ7-stigmastenol (IV), α-spinasterol (V), steryl (mixture of Δ7-stigmastenol and α-spinasterol)-β-D-glucopyranoside (VI, VII) and steryl (mixture of Δ7-stigmastenol and α-spinasterol)-6'-fatty acyl (mixture of palmitic acid and (Z, Z)-9, 12-octadecadienoic acid)-β-D-glucopyranoside (VIII, IX, X, XI) were identified.
