Tobacco tissue cultures grown in contact with lunar material from Apollo 12, for a 12-week period, resulted in fluctuations of both the relative and absolute concentrations of endogenous sterols and fatty acids. The experimental tissues contained higher concentrations of sterols than the controls did. The ratio of campesterol to stigmasterol was greater than 1 in control tissues, but less than 1 in the experimental tissues after 3 weeks. High relative concentrations (17.1 to 22.2 percent) of an unidentified compound or compounds were found only in control tissues that were 3 to 9 weeks of age.
用阿波罗 12 号采集的月球物质接触培养的烟草组织，经过 12 周的培养，导致内源性甾醇和脂肪酸的相对和绝对浓度都发生了波动。实验组织中的甾醇浓度比对照组高。在对照组组织中，菜油甾醇与豆甾醇的比值大于 1，但在实验组组织中，经过 3 周后，该比值小于 1。只有在 3 至 9 周龄的对照组组织中才发现相对浓度较高（17.1%至 22.2%）的一种或多种未知化合物。
