Therefore, development of technologies that allow the removal of toxic pollutants from wastewater is a need. Among all the common heavy metals treatment processes, biosorption is one of the more popular and efficient processes. The important number of publications concerning adsorption and remediation of metal ions from aqueous solution by natural and modified polysaccharides shows an increasing interest in biopolymer uses for environment preservation. The present review describes recent developments on biosorption processes using agricultural by-products, mainly mono- and polysaccharides extracted from natural resources. General considerations on metal ions complexation mechanism and interactions between metals and saccharides are first described. Then, a review on metal ions biosorption processes and recent development of new polysaccharide-based materials is carried out and shows their high adsorption capacities and their attractive character. Finally, advantages and possible limitations of using such biosorbents for metal ions adsorption process are discussed.","PeriodicalId":18897,"journal":{"name":"Natural products chemistry & research","volume":"252 2","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91476538","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}

The objectives of these studies were to survey the ethnobotanical uses of the three wild Zingiber species used by the local Dusun communities of Tambunan, to extract essential oils from the major Zingiber species and lastly to determine the chemical components in the essential oils and to test it against bacteria. Ethnobotanical uses for these three Zingiber species are as follow, Z. pseudopungens leaves and stem are bitter; Z. viridifalvum sap is drinkable, medicine as anti-venom for snake-bite, pith cooked as soup and whole plant is for decorations and Z. coloratum plant is used as decorations, rhizome boiled made into soup and medicinal to treat diabetes. In this study, the preliminary phytochemical screening in both polar extract of ethanol and non-polar extract of n-hexane showed the presence of major secondary metabolites in these 3 types of studied Zingiber spp. GC-MS profiling gave the composition of few major compounds. Moreover, antibacterial assays of these oils had demonstrated that the Gram-positive bacteria in this study were more sensitive to the Zingiber spp. samples compared to the Gram-negative bacteria.","PeriodicalId":18897,"journal":{"name":"Natural products chemistry & research","volume":"9 1","pages":"1-19"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89396366","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}
