作者等曾从十字花科植物PseuderucariaclavataO·E·Schulz中分＠1个山来酚3，7，4’三糖忒。今又报道从其中分得2个新的山来酚糖式，并阐明其结构式为山亲酚一3－O一新楼皮糖一4’－O一葡萄糖式（I）和其相应的7一葡糖式（且）（图1）。将干燥后的花和地上部分用70％乙醇提取
The authors and colleagues once divided @1 sarcomere 3,7,4’trisaccharide glycosides from the cruciferous plant Pseuderucariaclavata O.E. Schulz. It is reported that two new saccharose glucosides have been reported from this group, and its structural formula has been elucidated as a triterpenoid phenol 3-O-new loxogalactose-4’-O-glucose (I) and its corresponding 7 One glycosylated (and) (Figure 1). The dried flowers and aerial parts were extracted with 70% ethanol
