Abstract
|
|
|
Fourteen compounds were isolated from the 70% ethanol extract of Lonicera Caulis (Caprifoliaceae) and their
structures were identified as seven aliphatic compounds [long-chain alcohols (1, 2), trilinolein (3), hexacosanol (4), fatty acids (6), 9,12,13-trihydroxyoctadeca-10(E),15(Z)-dienoic acid (10), and pinellic acid (11)] and seven phenolics [bis(2-ethylhexyl) phthalate (dioctylphthalate, DOP) (5), coniferaldehyde (7), caffeic acid docosanoyl ester (8), caffeic acid (9), coniferyl aldehyde 4-O-glucoside (12), linarin (13), and coniferin (14)]. The chemical structures of these compounds were identified on the basis of spectroscopic methods and comparison with literature values. All the compounds except for caffeic acid (9) were isolated from this plant parts for the first time.
