In vitro studies of methanol and dichloromethanol extracts ofJuniperus oxycedrus L.

1997

The present study evaluated the effect of methanol and dichloromethanol extracts obtained from the leaves and stems of Juniperus oxycedrus against neurotransmitter-induced contraction in different isolated tissues of rats and guinea-pigs. Diverse concentrations of these extracts inhibit the concentration curve response to histamine, serotonin and acetylcholine. These results contribute to explaining the use of this plant in folk medicine. © 1997 John Wiley & Sons, Ltd.

Antimicrobial activity of selected plants employed in the Spanish mediterranean area. Part II

1989

The antimicrobial properties of 59 plants used in folk medicine to treat general infectious diseases were studied. The in vitro antimicrobial activity of chloroform and methanol plant extracts were assayed using the agar-streak method and 38 of them showed activity against some of the microorganisms tested. Bioautography established the probable active compounds. Inhibition bands were identified as containing terpenoids and polyphenolic compounds.

Flavonoids ofRhamnus lycioides; Part 2

1988

A review of some antimicrobial compounds isolated from medicinal plants reported in the literature 1978–1988

1989

This paper reviews the literature on recent antimicrobial plant products (1978–1988) and medicinal plants used for the treatment of infectious diseases. The review includes accounts of extracts, essential oils and other active principles isolated from plants that have been used in folk medicine as antimicrobial agents. The name and part of the plants studied, the spectrum of activity, type of active compounds and methods used are discussed, as are their mechanisms of action.

Cardiovascular effects of the methanol and dichloromethanol extracts fromTeucrium flavum L.

1998

The effects on arterial blood pressure and heart rate of the methanol and dichloromethanol extracts from Teucrium flavumL. were analysed in urethane anaesthetized rats. Mean arterial blood pressure was significantly reduced by the i.v. administration of both extracts to normotensive rats. The methanol extract also induced a decrease in the heart rate, while the dichloromethanol extract lacked any effect on this parameter. © 1998 John Wiley & Sons, Ltd.

Screening of antiinflammatory medicinal plants used in traditional medicine against skin diseases

1998

The antiinflammatory activity of twelve medicinal plants used against skin disorders were tested in different experimental models of topical inflammation and one in vitro inhibitory test against phospholipase A2 (PLA2) from Naja naja venom. Forsythia suspensa was the most active species on the arachidonic acid (AA) topical test. This last species together with Astragalus membranaceus and Ranunculus sceleratus were the most active on the 12-O-tetradecanoylphorbol-13-acetate (TPA) acute ear oedema test. Scrophularia auriculata was the most active on multiple topical applications of TPA and on the oxazolone-induced delayed type hypersensitivity (DTH). Santolina chamaecyparissus was the only sp…

Study of the antioedema activity of some seaweed and sponge extracts from the mediterranean coast in mice

1993

Chloroform and methanol extracts of ten marine species, seven seaweeds and three sponges, have been studied for possible, antioedema activities. The extracts were administered either topically or orally on TPA-induced mouse ear oedema and on carrageenan mouse paw oedema, respectively. The most interesting seaweed extracts were found to be from Corallina elongata, Galaxaura oblongata, Laurencia obtusa and Udotea petiolata, where both extracts of each species induced a large antioedema effect in both models employed. None of the sponges assayed demonstrated antiinflammatory effects on carrageenan mouse paw oedema, however, some extracts elicited an inhibition of the oedema developed by TPA.

Steroidal saponins from Dracaena marginata

2013

Three new steroidal saponins and ten known ones were isolated from the bark of Dracaena marginata, along with two known steroidal saponins from the roots. Their structures were elucidated on the basis of extensive 1D and 2D NMR experiments and mass spectrometry as (25R)-26-(beta-D-glucopyranosyloxy)3beta,22alpha-dihydroxyfurost-5-en-1beta-yl O-alpha-L-rhamnopyranosyl-(1 --> 2)-[alpha-L-rhamnopyranosyl-(1 --> 4)]-beta-D-glucopyranoside (1), (25R)-26-(beta-D-glucopyranosyloxy)-3beta,22alpha-dihydroxyfurost-5-en-1beta-yl O-alpha-L-rhamnopyranosyl-(1 --> 2)-4-O-sulfo-alpha-L-arabinopyranoside (2), and (25S)-3beta-hydroxyspirost-5-en-1beta-yl O-alpha-L-rhamnopyranosyl-(1 --> 2)-4-O-sulfo-alpha-L…

Antibacterial activity of flavonoids and phenylpropanoids from Marrubium globosum ssp. libanoticum.

2006

Marrubium globosum Montbr. et Auch. ex Benth. ssp. libanoticum Boiss. (Lamiaceae) is a medicinal plant used for the treatment of inflammatory diseases, asthma, coughs and other pulmonary and urinary problems. The goal of our study was to assess the biological activity of M. globosum testing the methanol extract of aerial parts for its antibacterial activity against bacteria known to cause respiratory, gastrointestinal, skin and urinary disorders; the extract showed antibacterial effects against all the strains of bacteria used. A purification of this active extract showed the presence, as main constituents, of verbascoside, isorhamnetin 3-O-beta-D-rutinoside, quercetin 3-O-beta-D-rutinoside…

Occurrence of resveratrol and pterostilbene in age-old darakchasava, an ayurvedic medicine from India

2000

'Darakchasava' is a well known Indian herbal preparation of which the main ingredient is Vitis vinifera L. This 'ayurvedic' medicine is prescribed as a cardiotonic and also given for other disorders. HPLC analysis of this age old formulation revealed the presence of polyphenols like resveratrol and pterostilbene. These phenolic compounds are now known as antioxidants, cancer chemopreventive agents, and also known to reduce mortality from coronary heart disease by increasing high density lipoproteins like cholesterol and inhibiting platelet aggregation (Soleas, J.S., Diamandis, E.P., Goldberg, D.M., 1997. Resveratrol: a molecule whose time has come? and gone? Clin. Biochem. 30 (2), 91-113). …
