从枳实精油中分离到了3个新的倍半萜和S-(+)-反式神经梨醇。它们的结构经核磁共振鉴定为2β，4β,9α-2,6,6,9-四甲基三环[6.3.0,0,2,4]十一烷基-1(8)-烯-7,11-二酮[1]，1β,2α,8β-2,6,10,10-四甲基双环[6.3]。O]十一-5-烯-2-醇（3 -羟基-6-星烯）[2]和1α，7β，9α-1-羟基-3,6,6,9-四甲基双环[5.4.0]十一-3-烯-8- 1[3]。
Three new sesquiterpenes, together with S-(+)-trans-nerolidol, were isolated from the essential oil of Lippia integrifolia. Their structures were elucidated by nmr spectroscopy as 2β,4β,9α-2,6,6,9-tetramethyltricyclo[6.3.0,0 2,4 ]undec-1(8)-ene-7,11-dione [1], 1β,2α,8β-2,6,10,10-tetramethylbicyclo[6.3.o]undec-5-en-2-ol (3a-hydroxy-6-asteriscene) [2], and 1α,7β,9α-1-hydroxy-3,6,6,9-tetramethylbicyclo[5.4.0]undec-3-en-8-one [3].
