Antibacterial activity of leaf and stem bark of Pterocarpus santalinus (Fabaceae) was investigated. The antibacterial activity was tested against both Gram-positive and Gram-negative organisms. Among the two extracts tested, stem bark extract exhibited broad-spectrum antibacterial activity against the tested organisms. The stem bark extract showed maximum activity against Enterobacter aerogenes...

Randia dumetorum Lam. (RD) (Rubiaceae) is traditionally used by some tribes of Assam and Manipur of North East India for the treatment of liver ailments. In this context, to scientifically validate this indigenous traditional knowledge, we have evaluated the antioxidant and hepatoprotective activity of RD leaf and bark. The methanol extracts of RD leaf and bark were evaluated for in vitro antio...

UNLABELLED BACKGROUND Pentacyclic triterpenes, mainly betulin and betulinic acid, are valuable anticancer agents found in the bark of birch tree. This study evaluates birch bark extracts for the active principles composition. RESULTS New improved extraction methods were applied on the bark of Betula pendula in order to reach the maximum content in active principles. Extracts were analyzed ...

Introduction and objective: Otitis externa, commonly called ear disease, is characterized by inflammation of the external ear canal. The aim of this study was to evaluate the antimicrobial potential of Cassia fistula flowers, leaves and bark extracts against Staphylococcus aureus, Proteus mirabilis, Escherchia coli, Pseudomonas aeruginosa, Acinetobacter sp., and Candida albicans, pathogens caus...

BACKGROUND Over exploitation of many traditional medicinal plants like Myrica esculenta has become a threat and in the near future, many medicinal plants may be unavailable for use of industry. OBJECTIVE Present study outlines the concept of plant part substitution. Stem bark and small branches of M. esculenta are compared on the basis of physicochemical analysis, phytochemical analysis, tota...

The present study describes the major content and antimicrobial activity of Azadirachta indica cell culture extracts. Major constituents of cell culture extracts were evaluated by HPLC and chromatographic analysis revealed that highest concentrations of azadirachtin (0.0069 % dry wt) synthesised by multiple shoot cultures. The results showed that multiple shoot cultures synthesised ~17-fold mor...

BACKGROUND Records have shown that Combretum adenogonium Steud. Ex A. Rich (Combretaceae) is used in traditional medicine systems of several tribes in Tanzania. This study focused on the investigation of antibacterial activity, anti-HIV-1 protease activity, toxicity properties and classes of phytochemicals in extracts from C. adenogonium Steud. Ex A. Rich (Combretaceae) to evaluate potential of...

Alpha-glucosidase inhibitory activity of fifteen Indian medicinal plants has been evaluated by in vitro enzyme assay. Methanol extracts of Cyperus rotundus (tubers), Plumbago zeylanica (root), Symplocos racemosa (bark), and Terminalia arjuna (bark) had displayed 100% inhibition with the IC50

objective(s):the current study was aimed to determine the bioactive constituents and biological effects of the crataegus monogyna ethanolic extracts from bark, leaves and berries on hypercholesterolemia. materials and methods: oleanolic acid, ursolic acid, quercetin and lupeol concentrations were quantified by hplc. total phenol content and radical scavenging activity of extracts were also meas...

Methanol extracts from the leaves, bark and roots of four Cameroonian medicinal plants, Bersama engleriana, Cupressus lusitanica, Vitellaria paradoxa and Guibourtia tessmannii were tested for their in vitro cytotoxicity, antigonorrheal and antireverse transcriptase activities. The XTT (2,3-bis[2-methoxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxyanilide inner salt) assay, the dilution metho...
