Chvar. Linalool (designated by later taxonomists as C. camphora var linaloolifera
(Fujita, 1967) consists of two further chemoforms : chforma 86% linalool and chforma
71% linalool (terminology of Tetenyi, 1970).
Hirota and Hiroi (1967) and Wan-Yang et al. (1989) recognised the following
chemical races among Chinese camphor trees:
(i) linalool type that yields 80% linalool and 10% monoterpenes;
(ii) cineole type having 76% cineole and 20% -terpene l, -terpenol;
(iii) sesquiterpene type having 40–60% nerolidol and 20% each of sesquiterpenoids
and monoterpenes;
