High Performance Liquid Chromatography Analysis o Sugars and Acid Components in ' Xintai Tianhong' Haw thorn Fruit.

[Objectives] This study was conducted to provide basic information for the utilization, quality control and deep processing of ' Xintai Tianhong' hav thorn fruit resources. [Methods] The contents of sugar and acid components in ' Xintai Tianhong hawthorn fniit were determined hv high performance liquid chn matography (HILC). Results] ' Xintai Tianhong' hawthorn fruit contained such four kinds of sugir components as fructose, sorbitol, glucose and sucrose, an such six kinds of organic acid components as oxalic acid, tartaric acid, malic acid, acetic acid, citric acid and succinic acid. The fruit had the highest sucrose cot tent, accounting for 70.53% of the total sugar content, followed by fructose, glucose and sorbitol. For the organic acid components, the content of succinic aci was the higfiest, accounting for47. 32% of the total acid content, followed by citric acid, malic acid, oxalic acid and tartaric acid, and acetic acid had the lowe content. [Conclusions] 'Xintai Tianhong' hawthorn sliould be a succinic acid-type hawthorn variety, which can be used as a parent in genetic research an breeding practice. [ABSTRACT FROM AUTHOR]
