Objective:To determine the antibacterial,antifungal,antiprotozoal,cytotoxic,and phytochemical properties of ethanol extracts of leaves of Voacanga globosa(Blanco) Merr.(V.globosa). Methods:The extracts were tested against bacteria and fungus through disc diffusion assay; against protozoa through growth curve determination,antiprotozoal and cytotoxicity assays. Results:The extract revealed antibacterial activities,inhibiting the growth of Staphylococcus aureus,Bacillus cereus,Pseudomonas aeruginosa,Micrococcus luteus,and Salmonella typhimurium.Antifungal assay showed that it inhibited Candida albicans.The antiprotozoal assay against Trichomonas vaginalis and Entamoeba histolytica showed that V.globosa can inhibit the parasites,wherein the action can be comparable to metronidazole.With the in situ cell death detection kit.Trichomonas vaginalis and Entamoeba histolytica exposed to V.globosa leaf extract was observed to fluoresce simultaneously in red and yellow signals signifying apoptotic-like changes.Preliminary phytochemical screening revealed the chemical composition of plant extract containing alkaloids,saponins,2-deoxysugars,and hydrolysabie tannins.Conclusions: Thus,thus study provides scientific evidence on the traditional use of V.globosa leaf extract in treating microbial diseases.Further,the leaf extract can possibly be used to produce alternative forms of antimicrobials.

Preliminary phytochemical screening revealed the chemical composition of plant extract containing alkaloids, saponins, 2-deoxysugars, and hydrolysabie tannins. Conclusions: Thus, which thus provides scientific evidence on the traditional use of V. globosa leaf extract in the corresponding microbial the disease extracts, the leaf extract can possibly be used to produce alternative forms of antimicrobials.

我们选取了三本新创的文学杂志进行抽样测试,除了《文艺风赏》为创刊后的第二期外,《天南》《大方》均是创刊号。测试分两个环节进行,先是参数测评,后是对其中一篇文章的细读考察。     封面设计  《天南》从容的艺术风范,一如市面上大多曲高和寡的艺术类杂志。跟绝大多数此类杂志不同,《天南》封底的奢侈品广告,大概也能说明他们的确不用再走传统文学期刊的路线了。《大方》的第一期封面已成为一个笑话,不是你买了图
