This study assesses the methanolic extracts of the leaves of three Piper species (Piper guineense Schum and Thonn., Piper nigrum L. and Piper umbellatum L.) (Piperaceae) for their polyphenolic concentration and free radical scavenging activity. The Folin-Ciocalteu method was used to assess the polyphenolic concentration while the reducing power, 1,1-diphenyl-2-picrylhydrazyl (DPPH), superoxide radical, hydroxyl radical, nitric oxide scavenging and metal chelating activities were employed in studying the radical scavenging activity of the extracts. All three spices exhibited a marked polyphenolic concentration and dose dependent free radical scavenging activity. The free polyphenolic concentration of the three spices was in the order P. umbellatum (15.9 +/- 1.9 mg/g) > P. guineense (12.6 +/- 0.3 mg/g) > P. nigrum (9.8 +/- 0.8). The three Piper extracts exhibited a 79.8-89.9% scavenging effect on DPPH, an 85.1-97.9% scavenging effect on nitric oxide at a dose level of 10 mg/ml and a 47.1-51.6% scavenging effect on superoxide radical at a dose level of 8 mg/ml extraction. Piper extracts also exhibited a 57-76.1% scavenging effect on hydroxyl radical at 5 mg/ml, a 0.4-0.6 reducing power and an 88.3-93.9% metal chelating activity at a dose level of 8 mg/ml of extract. Thus, these Piper species can play a role in the modulation of free radical induced disorders.","PeriodicalId":73776,"journal":{"name":"Journal of herbal pharmacotherapy","volume":"7 2","pages":"49-64"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"27274024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sephadex LH-20 Exclusion Chromatography was used by the fractionation of total extract and fractionation of low molecular weight polyphenols by liquid/liquid extraction. High Performance Liquid Chromatography was used to perform the composition in this low molecular weigh polyphenols fraction. The extract presented polyphenolic structures (54.78%) and other structural components (45.22%). Polymeric tannins were the major polyphenolic component (80%) and 20% were hydrolysable tannins. Epicatechin, catechin, chlorogenic acid, gallic acid and ellagic acid were monomeric structures determined in this extract. Phytosterols (0.0285%): stigmasterol, beta-sitosterol and campesterol were also present.","PeriodicalId":73776,"journal":{"name":"Journal of herbal pharmacotherapy","volume":"7 3-4","pages":"107-28"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15228940802142720","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"27797756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Cupressaceae) is widely growing on the rocky soils of the Mediterranean regions. In Jordan, the plant is distributed in different locations and is used as a folk medicine to treat rheumatism, edema, and urinary tract diseases. This study aimed to investigate the antifertility effect of J. phoenica in male albino rats. Animals were administered single daily intraperitoneal injections of 400 or 800 mg/kg of J. phoenica cones ethanol extract or the vehicle (dimethyl sulfoxide) for 21 consecutive days. A marked dose-dependent decrease in the counts and motility of the sperms collected from the cauda epididymis of treated rats was observed compared with the control. Furthermore, pregnancy rate in females markedly reduced by 60% and 80% after mating with males treated with 400 or 800 mg/kg, respectively. At the same time, significant decreases were detected in seminal vesicles and testicular weight of rats that received 800 mg/kg as compared with control rats. Testosterone levels were decreased significantly in both treated groups as compared with control. Histologically, seminiferous tubules of treated rats showed marked arrests of spermatogenesis and a marked decrease in the number of mature sperms. Therefore, the results of this study suggest that the ethanolic extract of the cones of J. phoenica possesses potential antifertility effects.","PeriodicalId":73776,"journal":{"name":"Journal of herbal pharmacotherapy","volume":"7 3-4","pages":"179-89"},"PeriodicalIF":0.0,"publicationDate":"2007-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/15228940802152463","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"27797759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
