Volatile Constituents from Flesh of Two Cucurbita Moschata by Head-Space Solid Micro-Extraction, Coupled With GC-MS

Abstract:

Objective: To study the volatile constituents from flesh of two Cucurbita moschata (Miben, Chaotianmiben). Method: The volatiles were analyzed by head-space solid micro-extraction, coupled with GC-MS and Kovats indices for the first time. A quantitative analysis in percent was performed by peak area normalization measurements. Result: Twenty-three compounds were identified from Miben and 32 from Chaotianmiben C.moschata 95.47% and 100.00% of the total essential constituents respectively. The two C.moschata had 19 common components. Conclusion: Hexadecanoic acid ethyl ester (18.64%), dihydroactindiolide(12.05%) were the highest components of the total essential constituents of C.moschata (miben). Hexadecanoic acid ethyl ester (22.68%), linolenic acid ethyl ester (15.57%) were the highest components of the total essential constituents of C.moschata(Chaotianmiben). The volatile constituents were different between the two C.moschata.
