Three kinds of explants from Cajanus cajan were used to established callus culture. Ethanolic extract prepared from five plant materials, callus from cotyledon, callus from hypocotyl, callus from root, Cajanus cajan seeds and Glycine max seeds were examined for their phenolic contents, flavonoids contents and DPPH radical - scavenging activity.

摘要 本研究建立培养树豆三种部位愈合组织，以总酚含量、总黄酮含量及DPPH自由基清除能力三种方式分析其抗氧化能力，并与成熟的树豆及黄豆种子比较；再利用genistein和daidzein两种标准品，检测这五种检品中大豆异黄酮的含量。

This product not only contains VA, VC, VE, VK, VB1, VB2, flavonoid, and coumarin etc., but also is replenished with hawthorn (containing large amount of malol,malic acid, VB2, VC, carotin, calcium, iron, phosporus, flavone and other nutritive substances and numerous alkaloids, more than twenty kinds of ingredients all together) and apricot, which make it more nutritious and easier to be absorbed by the body.

沙棘精不仅保留了沙棘中的维生素A、C、E、K、B1、B2、黄酮类、香豆素等成分，而且因添加了山楂（大量的熊果酸、苹果酸、维生素B2、维生素C、胡萝卜素、钙、铁、磷、黄酮素等二十多种营养物质和大量的生物碱）、杏，使其营养成分更加丰富并且更容易被人体均衡吸收。

To date, researchers have identified dozens of flavonoids in chaparral which act as cellular enhancers, as well as a powerful antioxidant called NDGA.

到目前为止，研究者们在矮橡树中发现了许多类黄酮，这些类黄酮被称为 NDGA ，是一种强大的抗氧化剂和细胞增强剂。

By the characteristic coloration reactions of the flavaonoids in comparison to UV and visible spectrum shown between the exWacted substance and turin.

采用不同的提取剂处理春花胡枝子叶，所得提取物与芦丁在紫外、可见光区的光谱对照及黄酮类化合物的特征显色反应，证明了春花胡枝子含有黄酮类化合物。

PAL activity, chitinase activity, total Polyphenol content and total Flavonoids content in soybean leaves induced by the same crude toxin and race were similar, it stated that the crude toxin is an important factor which can induce resistant substances, but the induced speed and the induced intensity by the crude toxin and conidium were different. Firstly, the induced speed of crude toxin which induced PAL activity and total Flavonoids content of resistant soybean varieties was faster than speed of C.

同一生理小种的粗毒素与灰斑病菌对大豆叶片内PAL活性、总多酚类含量、总黄酮含量以及几丁质酶活性等几种生化指标均表现出相似的诱导作用，由此可推断粗毒素是诱导大豆叶片内的PAL活性、总多酚含量、总黄酮含量以及几丁质酶活性产生变化的主要生物因子，只是二者在对抗性不同的大豆品种的诱导速度及强度上存在一定的差异。

The contents of total flavones in Marchantia convolute were determined through developed visible spectrophotometry. The reversed phase high performance liquid chromatography was set up to determine the contents of flavonoids in Marchantia convolute.

采用改进的铝盐显色分光光度法测定拳卷地钱总黄酮含量；采用反相高效液相色谱法测定拳卷地钱黄酮类化合物中芹菜素、槲皮素和木犀草素的含量。

Based on pigments and co-pigments analysis, fower color breeding towards true-red andblue in crape myrtle were discussed.

黄酮和黄酮醇是紫薇花瓣中重要的助色素物质。

In the present study, black soybean koji were first prepared with Aspergillus awamori. The change of total phenolics , isoflavone content and antioxidant activity of black soybean and black soybean koji after heating at various temperature（40,60,80,100℃）for 30 min and storage at 4℃ and 25℃ for 120 days under different packaging conditions（desiccant + deoxidant, desiccant, deoxidant , without desiccant and deoxidant）was investigated. The antioxidant activity examined included DPPH radical-scavenging effect, Fe2+-chelating effect, trolox equivalent antioxidant capacityand reducing power.

本研究以Aspergillus awamori作为菌酛制备黑豆麴，探讨黑豆及黑豆麴经不同温度（40、60、80及100℃）加热30分钟，以及在不同包装条件（乾燥剂+脱氧剂、乾燥剂、脱氧剂及不添加任何食品保存剂）与不同温度（4℃及25℃）下储存120天过程中总酚类化合物含量、总异黄酮素含量及异黄酮素组成及其甲醇萃取物抗氧化活性之变化，抗氧化活性之检测项目包括DPPH自由基清除能力、亚铁离子鳌合力、Trolox equivalent antioxidant capacity及还原力。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
