摘要:

山楂叶含有丰富的营养成分,具有多种保健功能。本文比较了不同品种山楂叶在不同时期的水分含量、色差、叶绿素含量、维生素C含量、总黄酮含量等,以分析山楂叶的品质特性,为山楂叶的加工及综合开发利用提供理论依据。结果表明,随着生长期延长,各品种山楂叶片的水分含量先升高后趋于稳定,叶绿素含量持续增加,维生素C含量先升后降,总黄酮含量在芽期最高,随后逐渐下降;不同品种山楂叶片的总色差在前期差异显著(p<0.05),后期差异不显著。各品种中,金如意芽期叶片的叶绿素、维生素C、总黄酮含量均较高,是较为合适的加工品种。相关分析表明,水分含量与叶绿素、总黄酮含量、总色差呈极显著(p<0.01)相关,叶绿素含量与总黄酮含量呈极显著负相关。研究结果为山楂叶的加工利用提供了理论依据。

Abstract:

Hawthorn leaves are rich in nutrients,with a variety of health functions. In this paper,the water content,color variation,chlorophyll,vitamin C and total flavonoid content of hawthorn leaves in different varieties and different periods were compared, in order to analyze the quality characteristics of hawthorn leaves,which provided a theoretical basis for the processing and comprehensive utilization of hawthorn leaves. The results showed that during the growth period,the water content of hawthorn leaves across different varieties first increased and then stabilized,while chlorophyll content continued to rise. Vitamin C content initially increased before declining,and total flavonoid content peaked during the bud stage before decreasing. Total color differences among hawthorn leaf samples were significant (p<0.05) in the early stages but not significant in later phases. Among the test varieties,the leaves of Jinruyi during the bud stage exhibited high contents of chlorophyll,vitamin C,and total flavonoid,making it a particularly suitable variety for processing. Correlation analysis revealed that water content exhibited a highly significant(p<0.01)correlation with chlorophyll content,total flavonoid content,and color difference;chlorophyll content showed a highly significant negative correlation with total flavonoid content. These findings provided a theoretical basis for the processing and utilization of hawthorn leaves.

Key words: hawthorn leaf, variety, stage, quality characteristic, flavonoid content
