Abstract

The oil was obtained from the seeds of groundcherry(Physalis alkekengi L.) native in Heilongjiang by the technology of ultrasound-assisted extraction method in 3 kinds of different solvent,respectively.The yields were n-hexane 17.26%(mass fraction,w),ethyl acetate 18.51%,diethyl ether 19.55%,respectively.The components of the oil were analyzed and identified by GC/MS,the results showed that groundcherry seeds oil contained linoleic acid(65%~75%),oleic acid(10%~15%),hexadecanoic acid(6%~15%) and octadecanoic acid(1.0%~3.5%).
