The results are as follows:The root of sanguisorba is abundant in starch (16.1%), tannis (8.85%), oligoprocyanidins (5.7%) and flavone (14.56%). The content in root is higher not only than stalk and leaves, but also than the normal plants.

研究结果表明：野生地榆的根中富含淀粉(16.1%)、鞣质(8.85%)、低聚原花青素(5.7%)以及黄酮类化合物(14.56%)，其含量不仅高于在茎和叶中的含量，也高于一般植物中的含量。

Plant polyphenols, an excellent natural antioxidant, has been studied extensively, while the extracting techniques of polyphenols, oligoprocyanidms and flavones in the root of sanguisorba haven't been reported in China.

植物多酚是一种优良的天然抗氧化剂，国内外从多个领域、多种角度对植物多酚进行了广泛的研究工作，而对地榆中多酚、低聚原花青素以及黄酮浸提工艺研究国内尚未见报道。

In lixiviating process, the preferable technical parameters of extracting tannis, flavone and oligoprocyanidins from the root and stalk of sanguisorba were obtained through changing the concentration of ethanol, particle size of raw material, the ratio of sample weight to solvent volume, the reflux temperature, extracting time and reflux times.

在常规浸提过程中，通过调节乙醇浓度、原料粒度、料液比、回流温度、回流时间、回流次数因素的影响，确定了地榆根和茎中鞣质、黄酮类、低聚原花青素较佳浸提工艺参数。

The research aimed to provide scientific basis for developing proanthocyandins from wild Vitis quinquangularis.

［目的］为进一步开发利用野生毛葡萄籽原花青素提供依据。

The SPC-2S fraction with 30% EtOH were constituted epicatechin and epicatechin gallate ester ;The SPC-2S fraction with 50% EtOH contained epicatechin and dimeric procyanidins, another SPC-3S contained epicatechin ,dimeric procyanidins and trimeric procyanidns ;Dimeric procyanidins and trimeric procyanidns constitute SPC-5S fraction;monomer dimer trimer tetramer pentamer of procyanidins were the major fractions in 70% acetone elute solution.

1和 2.01：1，也以添加0.1%SPC酒样中两者的比例最为协调；对小曲酒中酸的影响表现为，添加SPC后有利于降低酒样中乙酸的含量，各酒样中乙酸的量随着SPC添加量高粱外种皮中原花青素及其对小曲白酒挥发性成分影响机制研究的增加而降低；对醛类的影响为，添加SPC可降低酒样中糠醛的含量，其中以添加 0.1%SPC酒样中含量最低，为对照组的39.3%，而4个酒样中乙醛含量则无明显差别；低SPC添加量有降低酒样中杂醇油含量的趋势。

Young wine is packed with anthocyanins, which are very reactive: they interact with both sulphur dioxide and oxygen, which bleaches them.

新酒充满了活跃的花青素：它们与二氧化硫和氧气相互反应，并被漂白。

Concentration of anthocyanin in leaves of self-pollinated and cross-pollinated progenies was well correlated with the color of plants in the field.

杂交后代叶片的色素种类没有改变，但不同叶层的花青素含量有所变化，叶色表现出从里到外由深变浅的梯度变化。

The anthocyanin profile was analyzed by RP-HPLC, which showed five different anthocyanins in the extract, with the highest content of cyaniding -3-glucose.

结果表明，笃斯越桔多酚提取物中多酚含量占干质量的61.7%，花青素组分为5种，矢车菊素－3-葡萄糖普为其主要成分。

Red cell membrane damnified by oxidation can be recovered with LSPC at 5.0 g/mL, the fluorescence polarization degree of the membrane was similar to normal level, indicate that increased anisotropic by membrane oxidation decreased with LSPC.2 Antioxidation Effect of LSPC on skinLSPC can improve body antioxidation ability by increasing the antioxidase synthesis and its activity in skin and serum.

半体内法测得LSPC能显著激活NK细胞活性。表明，LSPC对免疫功能有较强的调节作用。4莲房原花青素对酪氨酸酶及黑色素生物合成抑制作用初步研究 LsPC对黑色素的生物合成有显著的抑制作用。7.8 X10一49/L一5.09几LsPc对酪氨酸酶活力有抑制作用，其中，7.8 X1049/L一0.19/L时，随LsPC浓度增大抑制率下降；0.lg/L~4.og/L时，随着LSPC浓度增大抑制率逐渐增高，最大抑制率高达99.9%，且该抑制作用属于可逆的竞争性抑制。

In this work, feasible qualitative and quantitative methods were established, and the procyanidins were fractionated according to their degree of polymerization.

由于原花青素强大的自由基清除能力、广泛的生理活性及出色的安全性，在营养及医学领域引起了越来越多的关注。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
