Methanol extracts prepared by mild and careful procedure from cultured cells of P___-. lobata were analyzed by reverse phase high performance liquid chromatography (HPLC) to reveal that most of the isoflavone 7-O___--glucosides daidzin(1) and genistin(2), and 8-C___--glucoside puerarin(3), exist as their 6"-O___--malonyl esters. The presence of malonyl esters of 1, 2 and 3 was also detected in the fresh roots and stems of P___-. lobata.
从培养的P___-. lobata细胞中,以温和且小心的程序制备的甲醇提取物通过反相高效液相色谱(HPLC)分析,结果显示大多数异黄酮7-O___--葡萄糖苷大豆苷(1)和芸苔苷(2),以及8-C___--葡萄糖苷黄芩苷(3)以其6"-O___--苯丙酰酯的形式存在。在新鲜的P___-. lobata根和茎中也检测到了1、2和3的苯丙酰酯的存在。
