Abstract:

To study the chemical constituents from the leaves of Dendrocalamus latiflorus, the compounds were isolated by column chromatography on silica gel, Sephadex LH-20, Prep HPLC and recrystallization. Their structures were elucidated on the basis of physicochemical constants and spectral analysis. Fifteen compounds were isolated and identified as luteolin, tricin, 7-methoxy-tricin, tricin-4'-O-glucopyranoside, tricin-7-O-glucopyranoside, apigenin, apigenin-7-O-glucopyranoside, apigenin-6-C-arabinfuranoside, apigenin-7-O-glucopyranoside-6"-O-rhamnoside, p-hydroxybenzaldehyde, 5-hydroxy-2-methoxy-benzaldehyde, loliolide, dehydrovomifoliol, vomifoliol-9-O-glucopyranoside, 4,4',9,9'-tetrahydroxy-3,3',5,5'-tetramethoxy-7,7'-monoepoxy lignan. The results of the research provided scientific basis for development and utilization of bamboo leaves. It established the foundation for clarification pharmacological activity of the leaves of Dendrocalamus latiflorus.
