摘要: 用葡聚糖凝胶和树脂层析技术从云南省昆明地区产怒江山茶(Camellia saluenensis Stapf ex Bean)的鲜叶中分离到11个酚类化合物,其中10个分别 鉴定为已知的槲皮素类黄酮化合物及原花色素类化合物。另1个为新的黄酮甙,经光谱与化学方法测定,其化学结构为槲皮素-3-O-β-D-木吡喃糖基(1→2)-α-L-鼠李吡喃糖基(1→6)-β-D-葡萄吡喃糖甙,命名为怒茶素。

Abstract: By means of column chromatography of sephadex and macroprous resin, a new flavonol glycoside,saluenin,was isolated from the fresh leaves of Camellia saluenensis together with ten known pheolic compounds. The structure of saluenin was identified as quercetin 3-O-β-D-xylopyranosyl(1→2)-α-L-rhamnopyranosyl(1→6)-β-D-glucpyranoside by spectral data and chemical methods.
