纯化

The macroporous resin AB-8 could be effectively used to enrich and purify the total terpenoid components from Alisma Orientalis.

AB-8大孔树脂可有效用于泽泻总萜醇类成分的富集与纯化。

The results showed that the resin AB-8 is the best in character of enrichment and purification of total terpenoid components from Alisma Orientalis. The optimal parameters were radius: height 1:10, the ratio of condensing 1:1, the speed of loading and eluting 10ml/min, the amount ratio of raw herb and resin 4.6:1, 70% alcohol as the elution solvent, the elution volume 4BV.

结果：以AB-8型树脂的富集纯化性能最佳，最优组合：半径、柱高比为1：10；药液浓缩比为1：1；药液上样与洗脱速度为10ml/min；药材与树脂的用量比为4.6：1；洗脱溶媒为70%乙醇；洗脱液量为4倍床体积。

Firstly , the V4 stock was purified three times by plaque formation. It's difficult to see clear plaques in CEF cells due to the avirulent characteristic , so we treated the V4 stock with trypsin and then allantoic Fluid and Mg2+ were added in the layer gel. In this case, we could see small plaques occasionally, but not stably.

本实验首先对实验室保存的V4株进行了三轮的蚀斑纯化，由于V4株属无毒株，其在CEF细胞中很难形成可见的蚀斑，因此我们采用了用胰酶处理V4病毒，并在上层胶中添加尿囊液及Mg2+，这样可以偶尔产生可见的蚀斑，但实验结果重复性很差。

Through active immunization of Inhibin antige n from porcine seminal plasma and super ovulation of allochthonous purified FSH, the effect of IB active immunization on cow was studied and its mechanism was al so further ascertained by examination of relative hormone concentrations in seru m at different physiological periold.12 Hostein cows and 12 Xiza young cows of 3 -5 years old (postpartum 50 d and above),were selected and divided into the exp e rimental group and control group randomly according to the estrum order.
