Abstract:

The volatile constituents from the buds and flowers of Malus halliana were analyzed by head-space solid-phase micro-extraction, coupled with GC-MS for the first time. Sixty-eight constituents were identified from the sample of M. halliana, sixty-three compounds from the buds, and twenty-four compounds from the flowers. Nineteen compounds were owned in both samples. Alkanes were the main constituents in buds (34.87%) and flowers (37.48%). The content of esters in buds (2.34%) was higher than that of flowers (0%), while the contents of acids and alcohols in buds (12.86% and 7.19%) were lower than those of flowers (31.49% and 7.76%). The resulta suggested that esters may be converted to acids and alcohols by hydrolase in the course of the buds blooming.

Key words: head-space solid-phase micro-extraction, volatile constituents, Malus halliana Koehne
