plumbago dawei/殺バクテリア剤

OBJECTIVE The current investigation was carried out to determine the cytotoxic and the antimicrobial activities of methanolic extracts of Plumbago zeylanica. METHODS The stems, leaves, and whole plants were air dried and extracted with methanol by using a Soxhlet extractor for 72 hours at 55 - 60°C.

This study evaluates the antibacterial, cytotoxic activities, and phytochemical composition, of Callistemon citrinus, Hibiscus rosa-sinensis and Plumbago auriculata leaves and flowers, three ornamental plants in Mexico. However, in other countries offers a range of other uses. Ethanol extracts of C.

The modulatory ability of plumbagin, a natural product from Plumbago zeylanica, was studied on peritoneal macrophages of BALB/c mice. The macrophage functions evaluated were bactericidal activity, hydrogen peroxide and superoxide anion release. The bactericidal capacity of in vivo plumbagin-treated

Herbal products derived from Hemidesmus indicus (L.) R. Br. ex Schult, Leucas aspera (Wild.), Plumbago zeylanica L., and Tridax procumbens (L.) R. Br. ex Schult. are widely used in traditional medicine. Though the extracts of these plants were found to be antimicrobial in nature and have the

In search of broad-spectrum antibacterial activity from traditionally used Indian medicinal plants, 66 ethanolic plant extracts were screened against nine different bacteria. Of these, 39 extracts demonstrated activity against six or more test bacteria. Twelve extracts showing broad-spectrum

Plumbagin (5-hydroxy-2-methyl-1,4-napthoquinone) is a bicyclic naphthoquinone, found in three major plant families viz. Plumbaginaceae, Ebenceae and Droseraceae. The phytochemical is reported to exhibit various pharmacological properties. In this study, plumbagin isolated from Plumbago zeylanica L.

Three naphthoquinones, plumbagin (1), 3,3'-biplumbagin (2) and elliptinone (3), isolated from Plumbago indica roots by antibacterial bioassay-guided isolation, were used as standard markers for quantitative determination. A reversed-phase HPLC method was established for the simultaneous

The extraction studies and a one-step purification of the crude extract of Plumbago indica using silica-gel vacuum chromatography provided a plumbagin derivative-rich P. indica root extract (PPE). The PPE was standardised to contain total plumbagin derivatives not less than 13% w/w. Antibacterial

Plumbagin, a naphthoquinone constituent of Plumbago zeylanica L. (Plumbaginaceae) is widely used in traditional Chinese medicine as an antifungal, antibacterial and anti-inflammatory agent. Plumbagin is known to exhibit proapoptotic, antiangiogenic and antimetastatic effects in cancer cells. The

The plant Plumbago zeylanica L. is a semi-climbing shrub that grows throughout Asia and Africa. In our previous study, P. zeylanica L. exhibited high anti-Helicobacter pylori and good bactericidal activities over a wide pH range (pH 2-7). Plumbagin - the major ingredient derived from the roots of P.

It has been shown that the presence of infection by Helicobacter pylori is strongly associated with gastric cancer and peptic ulceration. In western medicine, a 3-fold therapeutic regimen, emphasizing the use of antibiotics, is typically used to suppress H. pylori activity. However, antibiotic drug

Plumbagin, a naphtoquinone from the roots of Plumbago zeylanica is known to possess anticancer and anti-bacterial activity. Based on the former finding of our group in vitro demonstrating its effectiveness in human promyelocytic leukemia cells, NB4, in this study we further revealed the

Plumbagin, a naphtoquinone present in the roots of Plumbago zeylanica, has been reported to have many beneficial effects such as antibacterial, antifungal, anticancer, antimutagenic and antioxidant effects, but this compound has also been reported to have many side effects. Given the wide use of P.

UNASSIGNED Due to the importance of finding new and more effective antifungal and antibacterial compounds against invasive vaginitis strains, this study was conducted for fast screening of plant samples. UNASSIGNED Thirty Iranian plant samples were successively extracted by n-hexane, ethyl acetate
