不同产地牡丹籽营养成分与黄酮类物质的差异分析
Analysis of nutritional components and flavonoids in peony seeds from different origins
摘要
Abstract
This study aimed to investigate the variations in nutritional components and flavonoid profiles of peony seeds from different geographical origins.The contents of moisture,ash,crude fiber,starch,crude fat,total sugar,reducing sugar,and total phosphorus were determined according to national food safety standards.Principal component analysis(PCA)was employed to elucidate the relationship between nutritional components and geographical origins.Flavonoids were extracted from peony seed shells using ultrasound-assisted extraction with 50%ethanol,followed by purification with an AB-8 macroporous resin column.The flavonoid compositions were identified and quantified using high-performance liquid chromatography(HPLC)and liquid chromatography-mass spectrometry(LC-MS).The results indicated that peony seeds from Heze,Shandong,possessed higher sugar content,while those from Bozhou and Tongling in Anhui exhibited greater abundance in starch and crude fiber.Seeds sourced from Datong,Shanxi,showed a higher mineral content.Two primary flavonoids were identified in the peony seed shells:luteolin-C-glucose-O-glucoside and luteolin-7-O-rutinoside.The content of luteolin-C-glucose-O-glucoside was significantly higher in samples from Bozhou,Anhui(24.8%),compared to other regions,whereas the lowest content(20.5%)was found in samples from Linxia,Gansu.Significant variations existed in the nutritional components and flavonoid contents of peony seeds from different origins.These findings provide a scientific basis for selecting raw materials tailored to specific utilization requirements,and offer references for the efficient development and utilization of peony seed resources.关键词
