Three cerebrosides 2, 3, and 5 and two terpene glycosides 1 and 4 have been isolated from the methanol extract of the root of Aster scaber. Their structures were determined as 3-O-beta-D-glucuronopyranosyl-oleanolic acid methyl ester (1), (2S, 3S, 4R, 2'R, 8Z, 15'Z)-N-2'-hydroxy-15'-tetracosenoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (2), (2S, 3S, 4R, 8Z)-N-octadecanoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (3), 1alpha-hydroxy-6beta-O-beta-D-glucosyl-eudesm-3-ene (4), and (2S, 3S, 4R, 2'R, 8Z)-N-2'-hydroxy-hexadecanoyl-1-O-beta-D-glucopyranosyl-4-hydroxy-8-sphingenine (5) on the basis of spectroscopic methods.
从东风菜根的甲醇提取物中分离出了三种脑苷脂2、3和5以及两种萜烯糖苷1和4。基于光谱方法，它们的结构被确定为3 - O - β - D - 葡糖醛酸吡喃糖基齐墩果酸甲酯（1）、(2S, 3S, 4R, 2'R, 8Z, 15'Z) - N - 2' - 羟基 - 15' - 二十四碳烯酰基 - 1 - O - β - D - 吡喃葡萄糖基 - 4 - 羟基 - 8 - 鞘氨醇（2）、(2S, 3S, 4R, 8Z) - N - 十八烷酰基 - 1 - O - β - D - 吡喃葡萄糖基 - 4 - 羟基 - 8 - 鞘氨醇（3）、1α - 羟基 - 6β - O - β - D - 葡糖基 - 桉叶 - 3 - 烯（4）和(2S, 3S, 4R, 2'R, 8Z) - N - 2' - 羟基 - 十六烷酰基 -
