The essential oil composition of the roots and rhizomes of Siphonochilus aethiopicus
AM Viljoen, B Demirci, KHC Baser, B-E van Wyk
Abstract
The composition
of the essential oil obtained through hydrodistillation is reported for the
roots and rhizomes of Siphonochilus aethiopicus. The major
compounds in both the roots and the rhizomes are 1,8-cineole, (E)-β-ocimene,
cis-alloocimene, together with the recently reported furanoterpenoid
(4aα,5β,8α)-3,5,8a-trimethyl-4,4a,9-tetrahydo-naphtho[2,3-b]-furan-8(5H)-one
which is the major compound in both plant organs. The roots and rhizomes are
virtually identical in composition and provide a chemical rationale to promote
plant part substitution as a method to conserve this endangered South African
medicinal plant.
