Cyperus scariosus is a potential medicinal herb belonging to the family Cyperaceae. The GC-MS analysis of the oil showed cyprene (18.57 %) as the major terpene present in it. Cyprene was isolated from the non-polar fraction of the oil using hexane as solvent and characterized using TLC and spectral techniques (IR and 1H NMR). Cyprene was derivatized to cyprene epoxide by two methods i.e. using perbenzoic acid and epichlorohydrin. Further, the oil, it’s polar fraction (dichloromethane), non-polar fraction (hexane), cyprene and cyprene epoxide were screened for their plant growth regulating property in case of wheat seedlings (HD 2967 and PBW 621). Complete germination was observed above 2.5 μg/mL of all the test fractions in both the cultivars. Moreover, cyprene epoxide was found to be the most effective in enhancing the length of roots and shoots. Seedling vigour index was calculated in order to analyze the enhancement shown by the oil and its various components on the seedlings.
莎草 (Cyperus cariosus) 是莎草科莎草属的潜在药草。油的 GC-MS 分析显示,油中存在的主要萜烯是环
丙烯 (18.57%)。使用己烷作为溶剂从油的非极性馏分中分离出
环戊二烯,并使用 TLC 和光谱技术(IR 和 1H NMR)进行表征。通过两种方法,即使用过
苯甲酸和
环氧氯丙烷,将
环戊二烯衍生为
环氧化物环戊二烯。此外,还筛选了油、其极性馏分(
二氯甲烷)、非极性馏分(己烷)、环

环丙烷对小麦幼苗的植物生长调节特性(HD 2967 和 PBW 621)。两个品种的所有测试级分在浓度高于 2.5 μg/mL 时均观察到完全发芽。此外,
环氧化物被发现对于增加根和芽的长度最有效。计算幼苗活力指数,以分析油及其各种成分对幼苗的增强作用。
