Abstract: This study was aimed to analyze the volatile constituents from flower, stem tip and seed of Cucurbita moschata Duch.(Miben). The volatiles were analyzed by head-space solid micro-extraction, coupled with GC-MS and Kovats indices for the first time . The results showed that 22 compounds were identified from the flower , 20 from the stem tip and 21 from the seed of the C. moschata (Miben). The total essential constituents from each part were 91 . 89%, 89 . 24% and 96 . 26%, respectively . A total of 10 compounds in the flower and stem tip were mutual. And 3 compounds in the flower, stem tip and seed were mutual. It was concluded that the β-bourbonene (17.57%) and heneicosane (11.90%) were the highest components of the total essential constituents of the flower of C. moschata (Miben). Decanal (28.77%) was the highest components of the stem tip and hexadecanoic acid ethyl ester (29.12%), 2,3-butanediol (16.90%) and linoleic acid ethyl ester (16.52%) were the highest compo-nents of seed of C. moschata (Miben).
