Oxygenated terpenes represented 81% of the total, camphor being the main component (68%) and linalool the second most important (9%). The camphor content was similar to that described for Pakistan (Sattar et al., 1991) and Ivory Coast (Pelissier et al. 1995) leaf oils. The Ho-Sho leaf oil was almost exclusively formed by linalool (95%), with no other constituent representing more than 1%. In this the product is similar to the most common compositions described in the literature (Lin and Hua, 1987; Tao et al., 1987; Fujita et al. , 1974; Dung et al., 1993), where linalool content varied from 66 to 91%.
