Abstract [3H]5,8-Dihydroxypsoralen was effectively and selectively converted into 5,8-dimethoxypsoralen by roots of Ruta graveolens whereas [3H]8-methoxypsoralen and [3H]5-methoxypsoralen included for comparison were converted to a much lesser extent. These results indicate that 5,8-dihydroxypsoralen is a major physiological precursor of isopimpinellin.

5,8-二羟基补骨脂素在异辛平生物合成中的作用

摘要 [3H]5,8-二羟基补骨脂素被芸香的根有效且选择性地转化为5,8-二甲氧基补骨脂素，而用于比较的[3H]8-甲氧基补骨脂素和[3H]5-甲氧基补骨脂素的转化程度要小得多。这些结果表明 5,8-二羟基补骨脂素是异辛皮内林的主要生理前体。
