Two new phloroglucinol derivatives, isomallotolerin (1) and isomallotochromanol (2), were isolated from the cytotoxic fraction of the pericarps of Mallotus japonicus. The new derivatives were identified as 3-(3-methyl-2-hydroxybut-3-enyl)-5-(3-acetyl-2,4-dihydroxy-5-methy l-6- methoxybenzyl)-phlorisobutyrophenone (1) and 6-acetyl-5,7-dihydroxy-8-(3-acetyl-2,4-dihydroxy-5-methyl-6-methoxybenzy l)-2,2- dimethyl-3-hydroxychroman (2) from chemical and spectral data. Isomallotolerin and its acetate were found to be cytotoxic to KB cell line.
从日本野桐果皮的细胞毒性组分中分离出两种新的间苯三酚衍生物，异棉皮苷（1）和异棉皮色原烷（2）。根据化学和光谱数据，新衍生物被鉴定为3-(3-甲基-2-羟基丁-3-烯基)-5-(3-乙酰基-2,4-二羟基-5-甲基-6-甲氧基苄基)-间苯异丁酰苯（1）和6-乙酰基-5,7-二羟基-8-(3-乙酰基-2,4-二羟基-5-甲基-6-甲氧基苄基)-2,2-二甲基-3-羟基色满（2）。发现异棉皮苷及其乙酸酯对KB细胞系具有细胞毒性。
