Abstract:
The aqueous extract and volatile oil from SCGs were investigated. The aqueous
extract of SCGs was prepared from 15.58 g of dried SCGs in water (200 ml) using Soxhlet
extraction for 90 min. The aqueous extract was further investigated on ability to increase %
mortality of Aphis gossypii Glover by direct spray method. The result showed that after 72 h
using 0.6 and 1.2 %wt. /vol. of aqueous extract, the % mortality of A. gossypii Glover was 74
and 88 % respectively. Volatile oil from SCGs was extracted by Clevenger-type distillation
from 568.38 g of dried SCGs for 5.5 hours to yield 0.0200 g of volatile oil (0.0035%). The
volatile oil was yellow with strong coffee aroma. The chemical compositions of volatile oil
were studied using gas chromatography-mass spectrometry. The major components found in
volatile oil were α-pinene, α-thujene and phellandrene
