巴东皱皮木瓜发育及主要成分的变化分析

以湖北巴东产的皱皮木瓜为试验材料,分别在皱皮木瓜果实7个不同生长期采样,通过果实颜色、纵横径、鲜果质量等形态特征的测定,并采用HPLC法对不同生长期内的有效成分(齐墩果酸、熊果酸、原儿荼酸、绿原酸)进行检测,综合评价皱皮木瓜最佳的采收季节和质量指标.结果 表明:(1)皱皮木瓜的纵径、横径、鲜果质量增长随生长阶段呈逐渐递...

Change Regularities of Active Components from Fresh Fruit of Chaenomeles speciosa During Fruit Development

Taking Chaenomeles speciosa in Badong County of Hubei Province as experiment material,Chaenomeles speciosa fruits were sampled in seven different growing period,through the fruit color,the determination of vertical and horizontal diameter and fresh weight,morphological characteristics,and by the method of HPLC,the active components(oleanolic acid,ursolic acid,protocatechuic acid,chlorogenic acid)were detected at different growth period,the optimal harvesting season and quality indicators of Chaenomeles speciosa were comprehensively evaluated.Result shows that:(1)The longitudinal diameter,transverse diameter and fresh fruit weight of Chaenomeles speciosa increase gradually with the growth stage.(2)The content of active ingredients show a trend of increasing or decreasing in different growth periods.The contents of oleanolic acid and ursolic acid increase gradually during the whole development process,and increased significantly from July 10 to July 20.The contents of both reach the maximum at the maturity stage,while the contents of protocatechuic acid and chlorogenic acid remain relatively high at the young fruit stage,and the variation trend of them is descending-ascending-descending.
