A single dose of mevalonic acid-2-(14)C was administered simultaneously to 6 Haplopappus heterophyllus plants. They were harvested at intervals ranging from 3 days to 6 months. Four groups of biosynthetically related sterols were found to be radioactive in each plant, and the changes in radioactivity with time were studied. The most striking finding was a radioactive phenolic material present only in the 6-month plant, which had flowered.
将单剂量的 mevalonic acid-2-(14)C 同时施用于 6 株 Heterophyllus 属植物。在 3 天至 6 个月的时间间隔内收获它们。在每株植物中都发现了四组生物合成相关的甾醇具有放射性,并且研究了放射性随时间的变化。最引人注目的发现是仅存在于已开花的 6 个月植物中的一种放射性酚类物质。
