of calamondin (Citrus microcarpa) to form a deoxy derivative. This reaction indicated the presence in citrus of an epoxidase, which is required for the first step of the deoxylimonoidpathway. The product of the second step, deoxylimonic acid, was isolated from grapefruit seeds. Deoxylimonate A-ring lactone hydrolase, which is involved in the third step of the deoxylimonoidpathway, was also found
摘要 Methyl deacetylnomilate在calamondin (Citrus microcarpa)的叶子中代谢形成脱氧衍生物。该反应表明柑橘中存在环氧化酶,这是脱氧柠檬苦素途径的第一步所必需的。从葡萄柚种子中分离出第二步的产物脱氧柠檬烯酸。在葡萄柚种子中也发现了脱氧柠檬草酸 A 环内酯水解酶,参与脱氧柠檬苦素途径的第三步。这些结果和先前报道的该途径的第一个代谢物脱氧柠檬苦素的存在表明柠檬苦素在柑橘中代谢,不仅通过先前建立的 17-脱氢柠檬苦素途径,而且还通过脱氧柠檬苦素途径。
