Constituents from the roots of Hemerocallis fulva

초록

Besides chrysophanol and friedelin, mixtures of n-hydrocarbons [pentacosane (72.6%), heptacosane (14.6%), tetracosane (5.8%), nonacosane (4.1%) and hexacosane (2.9%)], n-hydrocarbon alcohols [octacosanol (70.5%) and hexacosanol (29.5%)], 1-monoacyl glycerols [acyl part; behenic acid (43.5%), lignoceric acid (32.4%), cerotic acid (9.3%), tricosanoic acid (8.9%), pentacosanoic acid (2.6%), octacosanoic acid (2.3%), heneicosanoic acid (1.0%)], wax esters [behenic acid (56.3%), lignoceric acid (23.0%), cerotic acid (19.8%), tricosanoic acid (4.6%), octacosanoic acid (4.0%), pentacosanoic acid (1.7%), triacontanoic acid (0.6%)/ octacosanol (33.7%), hexacosanol (21.0%), tetracosanol (15.6%), triacontanol (10.5%), docosanol (6.0%), tricosanol (6.0%), heptacosanol (4.2%), nonacosanol (3.0%)] and sterols [β-sitosterol (73.2%), stigmasterol (14.6%), campesterol (12.2%)] were isolated from the roots of Hemerocallis fulva. The acid: alcohol combinations of the major wax esters were C<inf>48</inf>: 22: 26, 24: 24, C<inf>46</inf>: 22: 24, and C<inf>44</inf>: 22: 22. This is the first report of 1-monoacyl glycerols and friedelin from this plant. All isolates were identified on the basis of spectral data and chemical reactions.
