APPLICATION OF MICROBIAL TYROSINASE ENZYME FOR INDUSTRY EFFLUENT TREATMENT CONTAINING PHENOL
Abstract: Phenolic compounds are the major pollutants found in the wastewater. Mostly phenolic compounds are derived from several industrial activities like leather, steel and iron manufacturing, petrol refining and also from mining industries (U.S.EPA, 1980). They are found highly toxic and corroding in nature. They are very harmful for living beings as they cause skin disease, respiratory and gastrointestinal ulcer, hematological changes, kidney and nervous system disorder.Traditional treatments like chemical oxidation …

Chemical Constituents and Tyrosinase Inhibitory Activity of Aqueous Fraction of the Leaves of Morus alba L. from Vietnam
Abstract: The mulberry has been widely cultivated to feed silkworms. The leaves of mulberry have been used in traditional medicine as an analgesic, antitussive, cathartic, diuretic. In this study we have isolated three compounds (LC1-3) by chromatographic methods from the Mulberry leaves (Morus alba L.) collected in Thai Nguyen province, Vietnam. These compounds were identified as: Kaempferol-3,7-di-O-α-L-rhamnopyranoside (LC1), 7,4’-dihydroxy-5,3’-dimethoxyflavone (LC2), (S)-5,5’,7-trihydroxy-2’,4’-dimethoxy-6-methylflavanone (LC3). Their structures were elucidated by spectroscopic methods, including MS …

Chemical Constituents and Tyrosinase Inhibitory Activity of Ethyl Acetate Extract of the Leaves of Morus alba L. from Vietnam
Abstract: AbstractFour compounds (DB1–4) were isolated from the Mulberry leaves (Morus alba L.) collected in Thai Nguyen province by chromatographic methods. These compounds were identified as: Kaempferol-3-O-β-D-glucopyranoside (DB1), quercetin 3-O-α-L-rhamnopyranoside (DB2), isofraxidin-7-O-β -D-glucopyranoside (DB3), and (±) -3, 5, 6, 7, 8, 4’-hexahydroxyflavane (DB4). Their structures were elucidated by spectroscopic methods, including mass spectrometry (MS) and nuclear magnetic resonance (NMR). Compound DB4 was isolated from Mulberry leaves for the first time. Compound …

Review on Unveiling the Shadow of Hyperpigmentation
Abstract: Natural products offer promising solutions for treating skin pigmentation disorders due to their non-toxic properties and effective mechanisms of action. Studies highlight their safety and efficacy through methods such as cytotoxicity tests, tyrosinase activity assays, and melanogenesis inhibition evaluations. Advanced delivery systems like liposomes and nanoparticles further enhance their performance by improving solubility and skin penetration. Skin pigmentation disorders, influenced by factors such as UV radiation, hormonal changes, and inflammation, …

Validation of Caratol E Tablet for its Melanogenesis Effect—In Vitro Study
Abstract: Vitiligo is a skin disorder characterized by pale patches due to lack of melanin. Lack of melanin may be due to reduced melanogenesis, lack of melanocytes and decreased tyrosinase activity. In the present study, Caratol E tablet was evaluated for its melanogenesis effect. Melanocytes viability was evaluated by MTT assay and tyrosinase assay. Caratol E tablet showed positive effect in increasing the melanogenesis. Results are discussed in the present paper. …
