[Chemical constituents from leaves of Phyllostachys pubescens I].

ABSTRACT

OBJECTIVE: To study the chemical constituents from leaves of Phyllostachys pubescens. METHOD: Column chromatography on sephadex LH-20 as well as preparative HPLC and spectral analysis were used to isolate and elucidate the constituents. RESULT: Six compounds were isolated from leaves of Phyllostachys pubescens, and identified as vanillin (I), syringic aldehyde (II), p-hydroxybenzaldehyde (III), vanillic acid (IV), syringic acid (V), 4-hydroxy-3-methoxy cinnamic acid, ethyl ester (VI). CONCLUSION: All above the compounds were isolated from the plant for the first time.
