Ten compounds have been isolated from the unused parts of Ammi visinaga. The isolated compounds were identified as tetracosanoic acid (1), β-sitosterol (2), visnadine (3), khellin (4), β-sitosterol glucoside (5), norkhellol (6), khellol (7), rhamnazin (8), cimifugin (9), and cis-khellactone-3’-β-glucopyranoside (10). The chemical structures of these compounds were elucidated based on spectrosco...

A pomegranate extract (PE) from the rind containing 90% ellagic acid was tested for its skin-whitening effect. PE showed inhibitory activity against mushroom tyrosinase in vitro, and the inhibition by the extract was comparable to that of arbutin, which is a known whitening agent. PE, when administered orally, also inhibited UV-induced skin pigmentation on the back of brownish guinea pigs. The ...

Epidermal melasma is a common hyperpigmentation disorder that can be challenging to treat. Although current treatment options for melasma are limited, topical skin-lightening preparations have widely been used as alternatives to hydroquinone. In this prospective, single-arm, open-label study, treatment of epidermal melasma with a novel cream formulation containing nicotinamide 4%, arbutin 3%, b...

Tea contains polyphenols and is one of the most popular beverages consumed worldwide. Because most tyrosinase inhibitors that regulate melanogenesis are phenol/catechol derivatives, this study investigated the inhibitory effects of Camellia sinensis water extracts (CSWEs), including black tea, green tea, and white tea extracts, on melanogenesis using immortalized melanocytes. CSWEs inhibited me...

Ethnomedicinal implies the usage of medicinal plants used by a group of people on account of their traditional knowledge and phytochemical means the individual chemical that plant contains. This review involves the ethnomedicinal and phytochemical perspectives of Pyrus communis Linn. In the “The Indian Materia Medica”, the common pear or gabbu gosha is considered as ‘Amritphale’ because of its ...
