capillary GC and GC-MS. Four chemotypes could be distinguished among the 115
progenies of a single camphor-rich mother tree (Table 9.10). The first group was rich
in camphor (75.8–80.6%), the second group contained 1,8-cineole and -terpineol as
major compounds (45–54% and 15–20%, respectively); the third group was rich in
E-nerolidol (43–22%) and 9-oxo-nerolidol (22–25%) (Table 9.10). The fourth group
contained a high proportion of safrole (36–58%), nerolidol (15–19%) and oxonerolidol
(6–12%). Progenies of a linalool rich mother tree was found to have six chemotypes:
(1) linalool type (90–93%); (2) camphor type (75–84%); (3) nerolidol (36–59%)
and oxonerolidol (19–29%) type; (4) camphor (36–66%) linalool (14–50%) type;
(5) 1,8-cineole type (53–54%); and (6) linalool (37.5%) 1,8-cineole (36.4%) type
(Table 9.11).
