It was investigated how to increase the yield and purity of tannin, flavone and oligoprocyanidms from the root and stalk of sanguisorba, and the stability of polyphenols from sanguisorba was studied, too. The chemical constitutes of sanguisorba were analyzed, the conditions on extracting tannin, flavone and oligoprocyanidins from sanguisorba by general lixiviating process and ultrasonic wave were optimize. The flavone and oligoprocyanidins were separated from sanguisorba and purified. The stability of polyphenol from sanguisorba was studied and the chemical structure of the products was analyzed.

肩周炎患者300例，分成B、F两组，B组仅用丙泊酚，F组使用丙泊酚和芬太尼。

Polyphenols and antioxidant capacity in different organs of Muscat Hamburg in the whole growth periods, and the effects of seedlessness treatment on polyphenols and antioxidant capacity of Muscat Hamburg were studied. The main results are as follows: 1. From the beginning of blooming period to the ripening period of Muscat Hamburg, the content of polyphenols in different organs decreased at first, and then increased with the development of the grape berry.

拟南芥药用成分主要有酚类化合物，即羟基苯丙烯酸酚类化合物的芥子酸酯，黄酮类化合物的4，5，7-三羟基黄酮衍生物，芥子酸酯与这种黄酮类化合物具有优良的减少紫外线危害和抗氧化作用。

Objective:To investigate the effect of total intravenous anesthesia with propofol on splanchnic perfusion in patients undergoing laparoscopic cholecystectomy.

目的：探讨异丙酚全凭静脉麻醉对腹腔镜下胆囊切除术患者内脏灌注的影响。方法：30例择期行LC患者，随机分为异氟醚静吸复合麻醉组和异丙酚全凭静脉麻醉组。

The research discover that starfruit polyphenols have thermal sensitiveity which obeys 1st order decay. Else, it has polyphenol oxidase in the extraction liquid. The decay constant of 35℃ is higher than others (35℃＞55℃＞70℃＞80℃).

研究中发现杨桃多酚具温度敏感性，随时间的增加以一阶方式衰退，此外还发现杨桃中含有多酚氧化酵素，使得在35℃时衰退常数kd = 4.34×10-3 min-1，较高温时要来的大，如70℃时kd = 3.33×10-3 min-1。

The supercritical fluid extraction of carbon dioxide owns lower extraction temperature and high diffuse coefficient. So, the technology is able to extract the thermal instable materials. In this study, we extract the polyphenols from damage starfruit by the supercritical carbon dioxide fluid and confer the extraction outcome. To seek the optimum operation conditions was the main purpose and provided the technology to starfruit processing industries.

超临界二氧化碳萃取技术具有低萃取温度，高扩散能力之特性，可将天然中热不稳定性物质萃出，并保留活性成分，所以本研究拟对受伤杨桃以超临界二氧化碳流体萃取技术进行杨桃多酚的萃取，并探讨杨桃多酚的萃取率，以提供杨桃汁制造业者回收杨桃之最佳化方法，并提高杨桃的附加价值。

The optimum conditions were starfruit weight (30 g), flow rate (9 NL/min), extraction time (45min), extraction pressure (4500 psi), extraction temperature (65℃), addition volume of ethanol cosolvent (40 ml), ethanol concentration (80%) and static supercritical extraction.

实验结果发现，本次实验最佳条件为杨桃量30 g、杨桃颗粒大小为中颗粒、泄压流速9 NL/min、萃取时间45 min、萃取压力4500 psi、萃取温度65℃、共溶剂乙醇的添加量40 ml 、共溶剂乙醇浓度80 %及萃取方式 SFE-静态，所萃取出之多酚含量1.302 mg/ml 大於非超临界萃取而相同萃取条件下之多酚量0.979 mg/ml。
