Abstract

Volatiles were distilled from leaves of three Bergenia species collected from Yunnan, Xinjiang and Tibet in western China and analyzed using GC/MS instrumentation. The contents of extractable volatiles varied substantially among the three species with B. crassifolia having approximately 0.05% dry wt (v/w), B. purpurscens 0.01% (v/w) and B. stracheyi 0.13% (v/w), respectively. In B. crassifolia, the main components were present as 3-methyl-2-buten-1-ol (26.56%), hexadecanoic acid (16.06%), dodecanoic acid (9.99%), linalool (5.63%) and octadecadienoic acid (4.10%). In B. purpurascens, the main components were β-eudesmol (18.63%), phytol (14.50%), hexadecanoic acid (13.05%), n-nonacosane (9.19%) and 3-methyl-2-buten-1-ol (7.52%). In B. stracheyi, 3-methyl-2-buten-1-ol was the dominant sort of volatile (52.71%), whereas detected major constituents included β-eudesmol (7.44%), damascenone (3.22%), caryophyllene (2.75%) and phytol (2.57%).
