Flavonoids were isolated from flowers of Salvia leucantha using chromatography separation techniques. The structure of the isolated compound was analyzed by chemical tests and spectroscopic methods such as UV, ^1H-NMR, and ^(13)C-NMR. The spectral data's proved its structure confirmed as Quercetin-3-O- α-L- rhamnopyranoside -2〞- gallate. The present study was to evaluate the agar diffusion antibacterial against gram positive and gram negative microorganisms and wound healing activities to…

Antibacterial, antioxidant, and topical anti-inflammatory activities of Bergia ammannioides: A wound-healing plant
This study presents scientific evidence for the efficacy of B. ammannioides in enhancing wound healing, and the first isolation of cyclolaudenol and cycloartenol from Bergia.
The Effect of Quercetin on Skin Wound Healing in Dexamethasone-Treated Rats
Some evidence is provided to support the use of quercetin to accelerating wound healing in dexamethasone treated animals, however, further research is needed to determine the quercETin mechanisms in acceleration of wound healing.
The Phytochemistry of Cherokee Aromatic Medicinal Plants
Several Cherokee medicinal plants are still in use today as herbal medicines, including, for example, yarrow, black cohosh, American ginseng, and blue skullcap.


Kaempferol-3-O-α-L-arabinopyranosyl(1→6)-β-D-galactopyranoside from Phytolacca octandra and its antimicrobial activity
Plants are the storehouse of chemicals that treat diseases by destroying microbes. Many plants and their constituents have been investigated for their antimicrobial activity [1, 2]. However, there is
In vitro screening of five local medicinal plants for antibacterial activity using disc diffusion method.
None of the five plant extracts tested showed antibacterial activities to gram negative E. coli and K. pneumoniae, except for A. paniculata and P. sarmentosum which showed activity towards P. aeruginosa, which forms a basis for further studies on screening of local medicinal plant extracts for antibacteria properties.

Control of Citrus Green and Blue Molds with Garlic Extracts
A remarkable increase in the activity of garlic extracts was observed when extracts were mixed with oil, and the treatment comprising 1% extract plus oil was as effective as the fungicide treatment in controlling both green and blue molds on Valencia oranges.
