摘　　要：目的:研究烟草废弃物不同提取部位的止血及抑菌作用,筛选止血和抑菌有效部位。方法:甲醇回流提取烟草废弃物,所得浸膏依次用石油醚,酸性乙酸乙酯,碱性乙酸乙酯和正丁醇萃取得各部位浸膏。首先通过体外凝血法(凝血板法和试管法)初步筛选有效止血部位,体内凝血法进一步考察初筛有效部位的不同剂量组对小鼠凝血时间的影响。将80只小鼠随机分为空白对照组,云南白药组(2 g·kg^(-1)),烟草废弃物石油醚部位高、中和低剂量组,酸性乙酸乙酯部位高、中和低剂量组。采用玻片法和毛细管法测量小鼠凝血时间,计算缩短率;采用微量稀释法测定烟草废弃物各部位对10种临床常见病原菌的最低抑菌浓度(MIC)。结果:体外凝血法表明:石油醚部位和酸性乙酸乙酯部位具有止血作用。体内凝血实验表明:与空白对照组比较,酸性乙酸乙酯部位的高、中剂量组可显著缩短小鼠的体内凝血时间,缩短率均高于60%(P<0.01),低剂量组可明显缩短小鼠体内凝血时间,缩短率高于39%(P<0.05)。酸性乙酸乙酯部位对痢疾杆菌,链球菌,白色念珠菌,犬小孢子菌,红色毛癣菌和石膏样小孢子菌有明显抑制作用,MIC值均小于6.25 g·L^(-1),对黑曲霉菌有一定的抑制作用,MIC值为50 g·L^(-1)。石油醚部位仅对白色念珠菌、链球菌和痢疾杆菌有较强的抑制作用,MIC值均小于50 g·L^(-1)。结论:酸性乙酸乙酯部位既有止血作用,又有抑菌作用,且抗菌范围广,故将酸性乙酸乙酯部位作为止血抑菌有效部位,为烟草废弃物的进一步开发利用提供依据。Objective： To screen the effective parts of Tobacco Waste through hemostatic and Anti-bacterial activities. Method： Tobacco waste was firstly extracted by methanol and followed by petroleum ether, acidic ethyl acetate, basic ethyl acetate, and n-butanol to obtain the different parts of extraction. Vitro hemostatic method （clotting plate method and the test tube method） was utilized to screen the effective hemostatic parts. Effects of different dosages of the effective part on coagulation time in Mice were furtherly verificated through vivo hemostatic method. Eighty mices were randomly divided into blank group, Yunnanbaiyao group （2 g.kg-1）, and high-, middle- and low-dose of petroleum ether and acid ethyl acetate parts groups. The clotting time was measured by the slide method and capillary tube method, and the shortened rate was calculated. Micro dilution method was chosen to determine the minimum inhibitory concentration （MIC） of 10 different clinical pathogens. Result： The vitro hemostasis is initially indicated petroleum ether part and acidic ethyl acetate part have a hemostatic effect, the high and middle dose groups of acidic ethyl acetate part could significantly shorten the clotting time with a shortened rate that greater than 60% （P〈0.01） and the low-dose group could obviously shorten the blood coagulation time with a shortened rate that higher than 39% （P〈0.05） from vivo clotting experiments. Acidic ethyl acetate part has a strong inhibitory effect on Shigella Castellani, Streptococcus, Candida albicans, Microsporum canis, Trichophyton rubidium（MIC is less than 6.25 g.L-1） and a certain inhibitory effect on Aspergillus niger（MIC is 50 g.L-1）.Petroleum ether part has a definite inhibitory effect on Candida albicans, Streptococcus and Shigella Castellani （MIC is lower than 50 g.L-1）. Conclusion： Acidic ethyl acetate part has obvious hemostatic and bacteriostatic effect, and the anti-bacterial range is wide. Therefore, acidic ethyl acetate part is the effective p
