clausena excavata/抗菌的

The antibacterial activity of different crude extracts of Clausena heptaphylla leaves as well as three purified coumarins, obtained from the cold methanol extract, is reported.

BACKGROUND The present study was designed to investigate the antibacterial activities of the methanol extracts from different parts of Beilschmedia acuta Kosterm (Lauraceae), Clausena anisata (Willd) Hook (Rutaceae), Newbouldia laevis Seem (Bignoniaceae) and Polyscias fulva (Hiern) Harms

OBJECTIVE Antimicrobial properties of medicinal plants and plant parts such as flowers, roots, fruits, seeds and oils are being used to cure some chronic and acute diseases throughout the world. In the present study, an attempt has been made to isolate and identify the antibacterial compound present

Two new C₁₃-norsesquiterpenes claulanterpene A (1) and B (2), together with two known sesquiterpenes (3-4), were isolated from methanol extract of the stem and leaf of Clausena lansium collected from Qingyuan county, Guangdong Province, China. Their structures

Clausena anisata is one of the medicinal plants used traditionally for treatment of parasitic infections, irritation (boils, ringworm, and eczema), flatworm infestations, influenza, abdominal cramps, and constipation. Phytochemical screening test of dichloromethane/methanol (1 : 1) roots

BACKGROUND There is wide spread interest in drugs derived from plants as green medicine is believed to be safe and dependable, compared with costly synthetic drugs that have adverse effects. METHODS We have attempted to evaluate the antioxidant, In vitro thrombolytic, antibacterial, antifungal and

Tobacco bacterial wilt caused by Ralstonia solanacearum is one of the most serious diseases of tobacco in the area of tobacco cultivation. As there is no effective control method for tobacco bacterial wilt diseases, developing new antibacterial agents in tobacco will make great practical sense. The

Three new carbazole alkaloids, harmandianamines A-C (1-3), together with fifteen known compounds (4-18) were isolated from the twigs of Clausena harmandiana. The structures were elucidated by spectroscopic methods, including UV, IR, NMR, and MS. The antibacterial activity against Escherichia coli

Five carbazole alkaloids, clausenawallines G-K (1-5), along with 12 known alkaloids (6-17) were isolated from the twigs of Clausena wallichii. Their structures were established using spectroscopic methods and the antibacterial activity of compounds 1-5 was evaluated.

Four new carbazole alkaloids, clausenawallines C-F (1-4), along with 18 known compounds (5-22) were isolated from the roots of Clausena wallichii. Compounds 3, 9, and 22 exhibited significant antibacterial activity against methicillin-resistant Staphylococcus aureus SK1 (MRSA SK1) and Staph. aureus

A new carbazole alkaloid, claulansine K (1), together with six known carbazole alkaloids (2-7), was isolated from the peels of Clausena lansium (Lour.) Skeels. The new compound was elucidated using a combination of 1D and 2D NMR (HMQC, HMBC, COSY, and ROESY) techniques, and HR-EI-MS analyses.

One new monoterpenoid, nerol oxide-8-carboxylic acid (1), and one new flavonoid glycoside, claulansoside A (2), together with six known compounds, clausenamide (3), quercetin (4), isorhamnetin (5), dihydromyric (6), 2",3"-dihydroxyanisolactone (7) and
