    • A method of separating ZE-nepetalactone and EZ-nepetalactone from catnip oil involving mixing catnip oil dissolved in at least one water immiscible, non-halogenated organic solvent with at least one inorganic base dissolved in water to form a biphasic mixture, stirring the biphasic mixture to hydrolyze ZE-nepetalactone to form ZE-nepetalic acid, separating the aqueous phase containing ZE-nepetalic acid from the organic phase containing EZ-nepetalactone in the biphasic mixture, and optionally acidifying the aqueous phase to about pH 4.5 and adding at least one water immiscible, non-halogenated organic solvent to azeotropically lactonize the ZE-nepetalic acid in the presence of a catalytic amount of p-toluene sulfonic acid to form ZE-nepetalactone.
    • 将脱乙酰壳多糖和己内酯从脱脂油中分离出来的方法,包括将溶于至少一种与水不混溶的非卤化有机溶剂中的至少一种无机碱溶解在水中以形成双相混合物,搅拌两相混合物 水解ZE-荆芥内酯以形成ZE-十六烷基酸,将含有ZE-脯氨酸的含水相从含有EZ-荆芥内酯的有机相分离在两相混合物中,并任选地将水相酸化至约pH 4.5并加入至少一种水 不溶混合的非卤化有机溶剂,以在催化量的对甲苯磺酸存在下共沸内酯化ZE-脯氨酸,形成ZE-脯氨酸内酯。
