Abstract

OBJECTIVE: To analyze the chemical constituents of volatile oil from flowers of Rhododendron mucronatum. METHODS: The volatile oil was extracted by water-steam distillation and analyzed by GC-MS. RESULTS: Forty-nine compounds, which occupied 79.55% of total constituents, were identified. The major constituents were linalool, beta-eudesmene, phytol, benzyl benzoate, benzyl salicylate and nonyl aldehyde. CONCLUSION: The chemical constituents of volatile oil, which contain many bioactive constituents, are mainly composed of terpenes, esters, and alkanes.
