By comparison with docosanoic acid and sulfurized ios-butyl olefin, it was found that when sulfur element was introduced into docosanoic acid, oxygen and sulfur elements showed synergistic friction-reducing, antiwear and load-carrying action. 通过与廿二酸和硫化异丁烯的对比研究发现,在廿二酸中引入硫后,氧与硫产生了明显的协同减摩抗磨及承载作用。
Besides the main constituents according with the literature, the many other new constituents were obtained from the species forthe first time, such as hexadecylenic acid, linolenic acid, arachidic acid, eicosenoic acid, and docosanoic acid. 结果:除主要成分与文献基本一致外,十六烯酸、亚麻酸、花生酸、花生烯酸及山嵛酸为首次在青果中发现。
