The chemical constituents in the Pu-erh tea were isolated by various column chromatographic methods, and their structures were identified by spectral data and physic-chemical analysis. As a result, eleven flavonoids were isolated and identified as kaempferol (1), quercetin (2), kaempferol-3-O-beta-D-glucopyranoside (3), kaempferol-3-O-beta-D-rutinoside (4), apigenin-6-C-alpha-L-arabinopyranosyl-8-C-beta-D-glucopyranoside (5), vitexin-4"-O-beta-D-glucopyranoside (6), kaempferol-3-O-[alpha-L-rhamnopyranosyl-(1--> 3)-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside] (7), quercetin3-O-beta-D-glucopyranoside (8), rutin (9), quercetin-3-0-alpha-L-rhamnopyranoside (10), and myricetin-3-0-beta-D-glucopyranoside (11). Compounds 5-7, 10 and 11 were isolated from Pu-erh tea for the first time.
采用多种柱色谱方法对普洱茶中的化学成分进行分离，并通过光谱数据和理化分析对其结构进行鉴定。结果，分离并鉴定出11种黄酮类化合物，分别为山奈酚（1）、槲皮素（2）、山奈酚-3-O-β-D-吡喃葡萄糖苷（3）、山奈酚-3-O-β-D-芸香糖苷（4）、芹菜素-6-C-α-L-阿拉伯吡喃糖基-8-C-β-D-吡喃葡萄糖苷（5）、牡荆素-4″-O-β-D-吡喃葡萄糖苷（6）、山奈酚-3-O-[α-L-鼠李吡喃糖基-(1→3)-α-L-鼠李吡喃糖基-(1→6)-β-D-吡喃葡萄糖苷]（7）、槲皮素-3-O-β-D-吡喃葡萄糖苷（8）、芦丁（9）、槲皮素-3-O-α-L-鼠李吡喃糖苷（10）和杨梅素-3-O-β-D-吡喃葡萄糖苷（11）。化合物5 - 7、10和11首次从普洱茶中分离得到。
