Identificaiton of Bombykol in Bombyx mandarina Females (Lepidoptera : Bombycidae)

Abstract

The presence of Bombykol, 10-trans, 12-cis-hexadecadien-1-ol in female Bombyx mandarina Moore was demonstrated by comparing the pheromonal activity, UV-absorption and gas liquid chromatogram of crude female extracts with that of B. mori and with authentic Bombykol. The purified active compound (12 μg) was isolated from 399 females of B. mandarina, whose mass spectrum and chromatographic behaviours were completely identical with those of authentic Bombykol.
