Abstract: To investigate the chemical constituents of phenolic acids in the whole herbs of Pothos chinensis. The chemical constituents were isolated and purified by various column chromatographic methods and preparative HPLC.Their structures were identified by physicochemical properties and spectral analysis.Nineteen compounds were isolated from the methanol extract and identified as benzoic acid (1),p-anisic acid (2),p-toluic acid (3),p-hydroxybenzoic acid (4),vanillic acid (5),syringic acid (6),3,4,5-trimethoxycinnamic acid (7),3,4-dimethoxycinnamic acid (8),ferulic acid (9),p-hydroxycinnamic acid (10),p-hydroxybenzaldehyde (11),vanillin (12),syringaldehyde (13),p-methoxyphenyl-propionic acid (14),p-hydroxyphenyl-propionic acid (15),(R)-2-hydroxy-1(4-hydroxy-3-methoxypheny)propan-1-one (16),ω-hydro-xypropioguaiacone (17),p-hydroxy phenylethanol (18),diisobutyl phthalate (19).Compounds 1-4 and 6-19 were isolated from the plants in this genus for the first time.
