Variance of Volatile Component from Prunus mume f.viridicalyx flower by Different Extraction Methods
On 13th March 2023,alabastrum of Prunus mume f.viridicalyx were collected in Changxing,Zhejiang province.Volatiles were extracted by headspace-solid phase microextraction,steam distillation and supercritical carbon dioxide,and analyzed by gas chromatography-mass spectrometry(GC-MS).The results revealed that there were 57 compounds extracted from alabastrum of P.mume f.viridicalyx belonging to 9 classes,including aldehydes,alcohols,ketones,and alkenes by three extraction methods.Benzaldehyde,nonanal,farnesol,benzoic acid,α-amyrin and D-limonene were identified as the main volatile components with benzaldehyde exhibiting the highest content.A total of 21 compounds were extracted by headspace-solid phase microextraction,consisting of aldehydes,alcohols and esters.30 compoundswere extracted by steam distillation,mainly comprising esters,alkene,ketones and other water-insoluble compounds.Supercritical CO2extraction resulted 30 compounds predominantly long-chain alkane and ester compounds.The experiment demonstrated that supercritical carbon dioxide extract had higher wax content,combination of headspace-solid phase microextraction and steam distillation proved to be more suitable detecting plant aromatic volatiles.
