Plumbago (family plumbaginaceae) is an evergreen shrub with colored flowers widely grown in a tropical climate, especially in Southeast Asia, South Asia and South African. There are many species of Plumbago e.g. Plumbago indica L., syn. Plumbago rosea with red flowers, Plumbago zeylanica with white flowers and Plumbago auriculata with blue flowers. Their major ingredients are napthoquinones suc...

Polyphenols have been implicated in the virulence and oxidant resistance of Cryptococcus neoformans. Although monomeric polyphenols did not protect against the prooxidant, plumbagin, polymeric dopamine-melanin conferred resistance both to hypochlorite and to permanganate. The physiologic antioxidant capacity conferred by melanin was found to be 21.3 x 10(-15) mole-equivalents per cell, a value ...

MarR negatively regulates expression of the multiple antibiotic resistance operon (marRAB) in Escherichia coli. In this study, it was demonstrated that sodium salicylate, plumbagin, 2, 4-dinitrophenol, and menadione-inducers of the marRAB operon in whole cells-all interfered with the repressor activity of MarR in vitro. It is proposed that these compounds can interact directly with MarR to affe...

The distribution of the naphthoquinones ramentaceone and plumbagin was studied among 50 taxa genus Nepenthes. Naphthoquinone patterns support classifications based on homology plastid and/or nuclear genes to some extent, with predominant in sections Nepenthes, Urceolatae, Tentaculatae, Regiae, Insignes Villosae, both isomers present without clear predominance Pyrophytae Montanae. Only 9 96 spec...

The biggest genus of flowering plants in the Plumbaginaceae family is called Plumbago indica L.

It an emmenagogue, abortifacient, alterative, carminative, stimulant, tomachic, vesicant. internally improve menstrual flow, cleanse blood, stimulate digestion,...

Gastroprotective effect of plumbagin and ethanolic extracts of Plumbaginales Journal of HerbMed Pharmacology, Volume 5, Number 3, July 2016 http://www.herbmedpharmacol.com 93 tus, cigarette smoking, family history of peptic ulcer and infection with H. pylori were all associated with increased risk of peptic ulcer. Separate analyses were performed by sex and occupational group to avoid confoundi...

Physicochemical parameters of roots of three Plumbago species, Plumbago capensis, P. rosea and P. zeylanica belonging to Plumbaginaceae were analyzed. Microbial contamination, aflatoxins, pesticide residue and heavy metal content were also determined. Attempt has also been made to estimate the biologically active chemical plumbagin present in them and the data compared. The study ensures that t...
