Two new iridoid glycosides, named scyphiphorins A (1) and B (2), together with four known compounds, geniposidic acid (=(1S,4aS,7aS)-1-(β-D-glucopyranosyloxy)-1,4a,5,7a-tetrahydro-7-(hydroxymethyl)cyclopenta[c]pyran-4-carboxylic acid; 3), 4-(4-hydroxy-3-methoxybenzyl)butan-2-one, oleanolic acid (=(3β)-3-hydroxyolean-12-en-28-oic acid), and stigmasterol β-D-glucoside (=(3β,22E)-stigmasta-5,22-dien-3-yl
两种新的鸢尾糖苷,分别称为鞘磷脂A(1)和B(2),以及四种已知的化合物,Geniposidicic acid(=(1 S,4a S,7a S)-1-(β -D-吡喃葡糖基氧基)-1 4a,5,7a-四氢-7-(羟甲基)环戊基[ c ]吡喃-4-羧酸; 3),4-(4-羟基-3-甲氧基苄基)丁酮-2-一,齐墩果酸(=(3 β)-3- hydroxyolean -12-烯-28-酸),和豆甾醇β -D-葡糖苷(=(3 β,22 ë)-stigmasta-5,22二烯-3-基β -D-吡喃葡萄糖苷)是首次从中国红树林的茎皮中分离出来的,Sphphiphora hydrophyllacea Gaertn。F。化合物1和2的结构确定为10- O-苯甲酰基己二酸和10- O -[(2 E,6 R)-8-羟基-2,6-二甲基-1-氧辛基-2-en-1-基]异己二酸,分别基于光谱数据和化学方法,包括2D
