BACKGROUND: Sea buckthorn (SBT) (Hippophae rhamnoides L.), a shrub rich with a huge variety of vitamins, antioxidants and other biologically active constituents with pharmacological and cosmaceutical applications. OBJECTIVE: The current review aims to compile the recent reported data on the ethnobotany, phytochemistry, biological activities and cosmaceutical uses of SBT plant from different regions of the world. METHODS: A wide-ranging inquiry on SBT was done electronically on the basis of articles and abstracts published in peer-reviewed journals, issued in conference proceedings, government reports, books, Master’s and Ph.D. theses etc. The research was carried out in different International scientific databases like Academic Search, Biological Abstracts, BIOSIS, BioOne Previews, CabDirect, Cochrane Library, Pubmed/Medline, GeoRef, Google Scholar, JSTOR, Journal Citation Reports, Mendeley, Publons, Researchgate, Scopus, SciELO, Springer Link, Science Direct, Web of Science, Taylor and Francis with particular keywords. RESULTS: A total of 185 published papers were assessed through the search approach and 162 papers were included published on SBT. It was evident from the literature search that the uses of SBT as traditional medicine so far against nearly 50 health related complications in more than 18 regions of the world are still a common practice where the decoction of leaves and juice/paste from berries/fruits of SBT were the common administration modes. Data on the phytochemical profile of SBT revealed more than 50 diverse reported groups of compounds with remarkable antioxidant activity against reactive oxygen species (ROS) using DPPH, FRAP and ABTS as common methods. Moreover to-date, the reported antimicrobial activity of SBT uncovered that the extracts from SBT were examined in contradiction of 32 strains of bacteria and 15 strains of fungus with significant inhibitory actions against the bacterial and fungal strains. The SBT extracts actions reported so far on different viral disease categories displayed active inhibition of the growth of nearly 15 different viral strains. The reported anticancer activity of compounds in SBT extracts to date evidenced remarkable results against more than 20 different cancer cell lines/ types. Moreover, SBT oil containing fatty acids, tocopherols and carotenoids is effectively used with cosmetics applications for skin care. CONCLUSIONS: Conclusively, SBT is rich with several remarkable phytochemicals that may have diverse biological actions and for that reason reassure the use of decoctions and/or infusions of SBT as folk traditional medicine around the world. Conversely, it is essential to explore the molecular mechanisms of compounds responsible for biological activites of SBT and to advance in the research of clinical uses and development of SBT based therapeutic and cosmetic products.
Some fungi are observed as effective pigments. Its importance in the production of natural pigments has grown significantly. The pigment-producing fungi were developed and evaluated for application in dyeing cotton fabric. In the research, five fungal strains were identified as Aspergillus terreus S10, Talaromyces atroroseus WW5A3, Penicillium oxalicum WW3A4 (DG), WW5C2 and WW31DG. These strains were incubated for 21 days under static and non-static conditions using MSM and PDB media. Under liquid state fermentation conditions, the production of the pigments by the fungus was improved by altering temperatures (25-35°C) and pH (4.5-6.5). T. atroroseus WW5A3 showed pinkish color, A. terrreus S10 displayed yellow color, P. oxalicum WW3A4 (DG) presented yellowgreenish, WW5C2 exhibited light yellow color and WW31DG demonstrated greenish color. The results showed the maximum percentage absorbance of T. atroroteus WW5A3 showed 90.36 % at 600 nm, A. terrreus S10 showed 88 % at 500 nm, P. oxalicum WW35A4 showed 46.04 % at 550 nm, WW5C2 showed 59.60 % at 550 nm, and WW31DG showed 81.9 % at 550 nm. The natural fungal pigments were tested against bacterial pathogens to check the antibacterial activity. The results indicated that S. aureus and E. coli exhibited antibacterial activity in terms of maximum zone of inhibition. In conclusion, out of five pigments producing fungi, Aspergillus terreus S10 and Talaromyces atroroseus produced maximum pigment and highest percentage absorbance under liquid state fermentation conditions. Potential applications in the textile and leather industries have been discovered as a result of this research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
