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.

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。
