The electrophilic, free radical and reactive oxygen species scavenging and detoxification potentials of Lophiraalata stem bark was evaluated. L. alata stem bark effectively scavenged DPPH radical, superoxideion and hydrogen peroxide. It produced 88% scavenging effect of DPPH radical at a concentration of 1.0 mg/ml. Aqueous extract of L. alata-stem bark produced 76% and 92% scavenging effect on ...

Background Staphylococcus aureus, methicillin-resistant and Escherichia coli, multidrug-resistant included in the list of antibiotic-resistant priority pathogens from WHO. As multidrug-resistant bacteria problem is increasing, it is necessary to probe new sources for identifying antimicrobial compounds. Medicinal plants represent a rich source of antimicrobial agents. One of the potential plant...

Plum bark necrosis stem pitting-associated virus (PBNSPaV) causes the plum bark necrosis stem pitting-associated disease. We obtained the complete genome of a PBNSPaV isolate (PBNSPaV-TA) using small RNA deep sequencing followed by overlapping RT-PCR. To our knowledge, this is the first report of a completed genome of PBNSPaV identified from cherry trees.

BACKGROUND Balanite aegyptiaca (L.) Delile, is a plant with extensive medicinal properties. Its stem bark is traditionally known for its spasmolytic and antiepileptic properties and used to treat yellow fever, jaundice and syphilis. Angiogenesis (sprouting of new blood vessels) is crucial for tumor growth and metastasis. The goal of this study is investigate the antiangiogenic, cytotoxicity and...

Ethanolic extract of bark of Azadirachta indica showed potent spermicidal activity when tested on rat spermatozoa in vitro. When the extract was applied in 1:1 and 1:2 ratio at tree different concentration using wet drop method, cent percent mortality of spermatozoa was observed within 10 seconds. 10% concentration of the extract was considered as an effective dose.

This study assessed the phytochemical contents of aqueous, ethanol, ethyl acetate and methanol extracts fruit, leaves, root, stem F. thonningii at selected concentrations. The alkaloids, tannins, saponins, volatile oils, phenols flavonoids were determined qualitatively in these results obtained showed that alkaloids are present roots barks Ficus thonningii. oil is found bark, root fruit (aqueou...

Chonemorpha grandiflora, (Roth) M.R. and S.M. Almeida syn C. fragrans (Moon), Alston (Apocynaceae) has been included in the list of an endangered medicinal plants. It is used in medicinal preparations like kumaryasavam and sudarsanasavum used as tonic. Entire plant, roots and root bark are used for fever and stomach disorders. The plant is useful in treatment of skin diseases and inflammations....

The aim of this study was to evaluate the heartwood, sapwood and bark content, and wood dry density in young and mature teak (Tectona grandis) trees. For this, 17 plantations were selected from 11 sites representing different climatic conditions and plantation densities (156 to 1600 trees ha–1, and line planting). From these plantations, a total of 87 trees with ages between 5 and 47 years were...

A phytochemical study of the stem bark of Vismia laurentii resulted in the isolation of a tetracyclic triterpene, tirucalla-7,24-dien-3-one (1), and seven other known compounds: 3-geranyloxyemodin (2), vismiaquinone A (3), vismiaquinone B (4), bivismiaquinone (5), epifriedelinol (6), betulinic acid (7) and stigmasta-7,22-dien-3-ol (8). The structure of all these compounds was elucidated by spec...
