Phytochemical investigation of has resulted in the isolation of four previously unreported isoflavones (1: -4: ) and eight known compounds (5: -12: ). Nine of these compounds (1: -6, 8: -10: ) are reported for the first time from members of the family Amaranthaceae. The structures of all isolated compounds were determined by spectroscopic methods, primarily one-dimensional and two-dimensional nuclear magnetic resonance and mass spectrometry. The absolute configuration of 6: was confirmed by circular dichroism. Inhibition of the organic anion transporters, OAT1 and OAT3, by the isolated compounds was evaluated. Among them, 7, 2'-dihydroxy- 6,8-dimethoxyisoflavone (1: ), 2'-hydroxy-6,7,8-trimethoxyisoflavone (2: ), 6,2'-dihydroxy-7,8-dimethoxyisoflavone (3: ), and 7-methoxyflavone (5: ) showed a significant inhibitory effect on 6-carboxyfluorescein uptake mediated by OAT1 and OAT3.
对……进行植物化学研究已分离出四种先前未报道的异黄酮(1: - 4: )和八种已知化合物(5: - 12: )。其中九种化合物(1: - 6,8: - 10: )首次从苋科植物中报道。所有分离化合物的结构通过光谱方法确定,主要是一维和二维核磁共振以及质谱。6: 的绝对构型通过圆二色性得到确证。评估了分离出的化合物对有机阴离子转运体OAT1和OAT3的抑制作用。其中,7, 2'-二羟基 - 6,8 - 二甲氧基异黄酮(1: )、2'-羟基 - 6,7,8 - 三甲氧基异黄酮(2: )、6,2'-二羟基 - 7,8 - 二甲氧基异黄酮(3: )和7 - 甲氧基黄酮(5: )对OAT1和OAT3介导的6 - 羧基荧光素摄取显示出显著的抑制作用。
