They are toxic, harmful & mostly carcinogenic. There has been a worldwide increase in the demand of natural dyes due to its therapeutic properties & no known side effects. The current research aimed at extracting dyes of different colors from natural plant sources, carrying out its characteristic analysis & its applications. The dyes were tested for their anti-microbial ability and were found to be inhibitory to common organisms like S. typhi, C. diphtheriae, S. aureus, etc. Phytochemical tests were performed and they confirmed presence of several important metabolites like Phenols, Tannins, Terpenoids, and many more. The dyes were tested for anti-oxidant activity using the FRAP assay and antioxidant levels ranging from 0.62 to 2.00 were obtained. Preparations of cosmetics like lip balms, was carried out, and dyes were also tested as natural food coloring agents. The results indicated that the dyes caused inhibition of wide range of bacteria and proved to be good sources of anti-oxidants. They departed a natural color to food items and hence can replace artificial food colorings. Thus the use of natural dyes should be promoted, as they are cheap, biodegradable and feasible.","PeriodicalId":8135,"journal":{"name":"Annals of Plant Sciences","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73549351","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 antimicrobial activity was determined by Agar well diffusion method and was screened against seven micro organisms. The highest antioxidant activities were observed in the methanol extracts of each plant, while the hexane extract showed the least activity irrespective of the method used.

The maximum tolerance has been exhibited by Aspergillus fumigatus as it grew up to twenty four percent concentration, however none of the other Aspergilli including both usar and fertile type showed such type of sustainability. Of the salts tested, Magnesium sulphate seemed to be the salt of more utility to both types of isolates as exhibited by their growth at different concentration levels and further all the Aspergilli tested showed more physical growth at different concentrations of this salt in comparison to other two salts tested. Salinity also affected the sporulation of different Aspergilli .

Numerous studies have reported that continuous exposure to reactive oxygen species can stimulate skin aging and that excessive accumulation of fat can cause an impaired skin barrier and tissue structure alterations. Thus, the maintenance of antioxidant homeostasis and the suppression of adipose accumulation are important strategies for skin anti-aging.

The family being one of the most evolutionarily successful and advanced taxa shows astonishing level of diversity reflected in the form of various types of adaptations. The high level of diversity within the family in addition to other unusual features have reflected in poor understanding of its phylogenetics. Fossil record of angiosperms particularly of Solanaceae) is very meager and relatively recent, so use of morphology and other conventional characters is not convincing in revealing true phylogeny of the family. This all has necessitated using alternative marker types in phylogenetic analysis of the family. Since advent of molecular biology molecular markers have been constantly refined to serve the purpose. Solanaceous species, such as tomato, potato, chilli pepper, tobacco, and petunia serve as model systems for the investigation of molecular and agronomic questions, and the family is the subject of intensive phylogenetic studies that are providing new insights into species boundaries and generic relationships. Results from recent morphological, molecular, and biosystematic research have shed new light on the systematic relationships in the family at virtually all taxonomic levels from subfamily to variety.","PeriodicalId":8135,"journal":{"name":"Annals of Plant Sciences","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88607945","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}
