- W978802055 abstract "用高效液相色谱-二极管阵列检测器及高效液相色谱-质谱联用技术,发现常压及减压干燥能使粗榧提取物中两个主要的化合物（1号峰和2号峰）发生降解。减压干燥后两个化合物分别减少了20.2%和45.6%,常压干燥后,两个化合物均检测不到。与干燥前相比,减压干燥和常压干燥使3号峰面积分别增加了1.90倍和5.74倍。1-3号峰均具有特征性的黄酮化合物的两个紫外吸收带（240-280 nm和300-400 nm）,被推测为黄酮化合物,质谱研究推测1-2号峰发生了苷键断裂生成3号峰。用AB-8大孔吸附树脂,葡聚糖凝胶LH-20,反相硅胶（ODS）柱色谱分离纯化得到1-3号峰的3个化合物,对其进行了红外和核磁测定,鉴定出芹菜素-5-O-α-L-吡喃鼠李糖基（1→4）-β-D-吡喃葡萄糖苷和芹菜素-5-O-α-L-吡喃鼠李糖基（1→4）-6″-O-乙酰基-β-D-吡喃葡萄糖苷两个黄酮苷,干燥过程使它们苷键断裂生成了苷元芹菜素（3号峰）。" @default.
