Abstract :The essential oil(this will hereafter be refered to as HE)obtained by steam distillation of leaves and branchlets of Vitex trifolia,L.(so-called Mitsuba-Hamago or Tachi-Hamago)was removed fatty acids and phenols containing in it by washing with alkali solution and carried out as the following methods.a)Fractional Distillation b)Gas Chromatography c)Infra-Red Spectroscopy As the resu1t,the next facts were known.(1)The HE was separated into twelve fractions.(2)Monoterpenoids,such as α-Pinene,β-Pinene and Limonene,are contained in the HE as main components. These substances were identified by a comparison of their Gas Chromatography and IR Spectra with those of pure reference compounds.(3)The distillated fractions,HE7,8~HE10,seem to be alcohol, Ketone and ester(acetate)of monoterpenoids.(4)Considering the b.p.,130-140℃/14mmHg,the distillated fractions,HE11 and HE12,seem to be sesquiterpenoids,C_<15>H_<24>.(5)In a paper, the author Shinozaki reported that the essential oil extracted from Vitex trifolia,L.var.ovata Makino produced in Ogasahara islands contains Camphene.However,the Camphere did not be contained in our HE.
