Chemical Composition of the Essential Oils from Flowers of Senecio vernalis and Senecio platyphyllus var. platyphyllus

摘要

Two essential oil samples obtained by hydrodistillation from the flowers of Senecio vernalis Valdst. & Kit.,(Asteraceae) and Senecio platyphyllus DC. var. platyphyllus,were analyzed by GC-FID and GC-MS. 69 compounds in the oil of S. vernalis,representing 93.4 % and 48 compounds in the oil of S. platyphyllus var. platyphyllus,representing 94.4 %,were identified. The essential oils were rich in monoterpene (53.3 %) and sesquiterpene (76.1 %) hydrocarbons with P-pinene (13.0%) and (E)-caryophyllene (28.6 %) as the major compounds,respectively.
