Abstract
The aim of this research was to determine the chemical constituents and
toxicities of essential oil derived from Alpinia blepharocalyx rhizomes
against the cigarette beetle, Lasioderma serricorne (Fabricius). Essential
oil of A. blepharocalyx rhizomes was obtained from hydrodistillation and was
investigated by Gas Chromatography-Mass Spectrometry (GC-MS). A total of 46
components of the essential oil of A. blepharocalyx rhizomes were identified.
The principal compounds in A. blepharocalyx essential oil were camphor
(23.13%), sabinene (11.27%), α-pinene (9.81%) and eucalyptol (8.86%) followed
by camphene (8.05%), sylvestrene (5.61%) and α-phellandrene (5.00%). Among
them, the four active constituents, predicted with a bioactivity-test, were
isolated and identified as camphor, sabinene, α-pinene and eucalyptol. The
essential oil of A. blepharocalyx possessed strong contact toxicity against
the cigarette beetle with LD50 value of 15.02 μg adult-1, and also exhibited
strong fumigant toxicity against L. serricorne adults with LC50 value of 3.83
mg L-1 air. The results indicate that the essential oil of A. blepharocalyx
shows potential in terms of contact and fumigant toxicities against stored
product insects.
