caesalpinia sappan/殺バクテリア剤

To study chemical constituents contained in roots of Caesalpinia millettii by HPLC. Six homoisoflavonoids were identified by spectroscopic data and physicochemical property as eucomin (1), intricatinol (2), 8-methoxybonducellin (3), bonducellin (4), 8-methoxyisobonducellin (5) and

Gallotannins obtained from tara pod extracts (EE) and from the products of acid hydrolysis for 4 and 9h (HE-4 and HE-9) were characterised for their composition, antioxidant activity, antimicrobial activity (AA) and minimum inhibitory concentration (MIC). Results of AA and MIC showed that EE exerted

Phytochemical study on the methanolic extract of Caesalpinia crista afforded two novel compounds, 2-hydroxytrideca-3,6-dienyl-pentanoate and octacosa-12,15-diene along with known compounds 3-O-methylellagic acid 3'O-α-rhamnopyranoside, β-sitosterol and sucrose. Compound 3-O-methylellagic acid

A new compound 1 was isolated from the methanolic extract of the stems of the Caesalpinia pulcherrima Linn. along with a reported compound (2) 3-O-β-D-glucopyranosyl-(1→4)-β-D-xylopyranosyl-(1→3)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranosyl hederagenin

Anisotropic snowman-like silver nanoparticles (AgNPs) were synthesized using the extract of Caesalpinia sappan heartwood as a reducing agent in the presence of cetyltrimethylammonium bromide. Two surface plasmon resonance bands of the orange solution were observed at 446 nm and 539 nm in UV-visible

Extracts from various organs of 25 plants of Brazilian traditional medicine were assayed with respect to their anti-bacterial activities against Escherichia coli, a susceptible strain of Staphylococcus aureus and two resistant strains of Staphylococcus aureus harbouring the efflux pumps NorA and

OBJECTIVE To determine the antibacterial activity of six kinds of natural herbs in Yunnan on normal oral predominant bacteria in vitro. METHODS Agar dilution method, the antimicrobial susceptibility testing of anaerobes which was recommended by National Committee for Clinical Laboratory Standard

BACKGROUND Brazilin is a major active principle of Caesalpinia sappan L. (Leguminosae or Fabaceae). For industry aspects, brazilin-rich extract (BRE) has been prepared and standardized to contain 39% w/w brazilin. BRE may have more advantages than brazilin in term of a lower-cost production

BACKGROUND Chronic wound is caused by various factors such as chemotherapy, gene damage, treatment with steroids, diabetes mellitus, renal failure, blood pressure, infection and nutritional factors. One of the most common causes is bacterial infection. Antibacterial activity of several herbal plants

BACKGROUND Many medicinal plants from Leguminosae family can be found easily in Malaysia. These plants have been used as traditional medicines by local ethnic groups, where they are prepared as decoction, pastes for wound infections, and some have been eaten as salad. This paper focused on the

Antimicrobial resistance has been increasing in recent years and is most frequently found in pathogenic microorganisms resistant or multiresistant to drugs. The secondary metabolites of plants have been evaluated as alternatives for control and treatment of these microorganisms. The aim of this

Bioactivity-guided fractionation of the light petroleum extract of Caesalpinia benthamiana (=Mezoneuron benthamianum) root bark has led to the isolation of two cassane diterpenoids, designated as benthaminin 1 and 2. A third compound, a deoxy form of caesaldekarin C (also referred to as methyl

OBJECTIVE The plant species reported here are traditionally used in Northern Peru to treat bacterial infections, often addressed by the local healers as "inflammation". The aim of this study was to evaluate the minimum inhibitory concentration (MIC) of their antibacterial properties against

Nine ethanol extracts of Brunfelsia grandiflora (Solanaceae), Caesalpinia spinosa (Caesalpiniaceae), Dracontium loretense (Araceae), Equisetum giganteum (Equisetaceae), Maytenus macrocarpa (Celastraceae), Phyllanthus amarus (Euphorbiaceae), Piper aduncum (Piperaceae), Terminalia catappa

Crude seed coat extracts from Abrus precatorius and Caesalpinia crista were purified into four different fractions namely phenolic acids, flavonols, flavanols and anthocyanin which were then examined for their polyphenol contents and antimicrobial potentials. The fractions derived from seed coat of
