半枝莲甜菜红素提取物清除自由基与抗氧化能力与甜菜红素含量有关。

The free radical scavenging effects and antioxidation ability of betacyanin extract were related to its betacyanin content . 4 .

随着光强度的升高，甜菜红素含量基本上呈现先上升后下降的趋势。

Betacyanin content initially increased and reached the highest level at a certain light quantity , but then declined with an increase in white , red or blue light intensity .

研究取得的结果与结论如下：1.通过对半枝莲红色素的溶解性质观察、薄层色谱法和紫外可见波谱扫描分析推知，该红色素即为甜菜红素，但其结构类型需进一步确证。

The results were as follows : 1 . The red pigment in Portulaca grandiflora Hook extract was identified as betacyanin by analyzing solubility properties and TLC and UV-Vis Scanning spectroscopy analysis , however the structure type needs further identification . 2 .

本文采用超滤-纳滤两次分离的方法，对红甜菜块根甜菜红素进行分离、精制和浓缩，并采用高效液相色谱法进行了提纯，通过质谱进行有效成分鉴定。

This paper adopted the method of separation-ultrafiltration-nanofiltration . Red element of the root of red beet can be separated , refined and enriched . It was purified by HPLC and was identified about the effective constituents by mass spectrometry .
