TL;DR: The observation that phytochemicals from foods can inhibit QS related processes opens up an exciting new strategy for antimicrobial chemotherapy and lead to the discovery of new category of antibiotics which can overcome the issues related to antimicrobial resistance.

TL;DR: The essential oil of Z. piperitum fruit may prove useful in the development of mosquito repellents as an effective personal protection measure against mosquito bites.

TL;DR: Treatment with hydro-ethanolic extract of C. procera flowers has brought back the altered levels of biochemical markers to the near normal levels in the dose dependent manner.

TL;DR: Five aromatic plants, Carum carvi (caraway), Apium graveolens (celery), Foeniculum vulgare (fennel), Zanthoxylum limonella (mullilam) and Curcuma zedoaria (zedoary) were selected for investigating larvicidal potential against mosquito vectors.

TL;DR: A series of research on plants used in Calabria (Southern Italy) in the folk plant medicine was carried out in the last twenty years, finding the use of 104 taxa distributed into 42 families are described.

TL;DR: The results obtained suggest that the aqueous leaf extract of B. coccineus is endowed with effective antiinflammatory activity mediated via either inhibition of phospholipase A(2) (PLA(2)) activity or cyclooxygenase cascade and by blocking the release of vasoactive substances (histamine, serotonin and kinins).

TL;DR: Garcinia mangostana was highly effective in scavenging free radicals and was able to suppress the production of pro-inflammatory cytokines, which could be useful in treatment of acne vulgaris.

TL;DR: In the present review the literature data on the phytochemical and biological investigations on the genus Fraxinus are summarized up to the middle of 2004.

TL;DR: Aloe vera fresh leaves hydroalcoholic plant extract was tested against the mycelial growth of Botrytis gladiolorum, Fusarium oxysporum f.sp.

TL;DR: Rats treated with high rate of wound contraction significantly decreased epithelization period, significant increase in dry weight and hydroxyproline content of the granulation tissue when compared with the controls support the use of C. roseus in the management of wound healing.

TL;DR: Results show that the secondary metabolite biosynthetic capacity of Passiflora tissue cultures can be enhanced by appropriate forms of elicitation, including UV-B irradiation and methyl jasmonate.

TL;DR: Certain combinations of the two molecules led to a synergistic effect, which is interesting in the view of potentiating their inhibition of C. albicans colonisation and infectiousness.

TL;DR: Aqueous extract of Zizyphus lotus showed a significant and dose-dependent antiinflammatory and analgesic activity and was given intraperitoneally for the first time.

TL;DR: Acetoxycentellynol, a C(15)-polyacetylene, was found to be accumulated up to 18 times more in in vitro plants as compared to plant material collected in situ, and in vitro propagation of C. asiatica was successfully achieved in hormone-free medium.

TL;DR: Seabuckthorn (Hippophae rhamnoides) seeds aqueous extract was screened for antioxidant and antibacterial activities and showed a good antioxidant activity.

TL;DR: A pronounced anabolic and spermatogenic effect was evidenced by weight gains of reproductive organs and enhanced attractability towards female in rats treated with ethanolic extract of rhizomes.

TL;DR: The essential oil obtained from the leaves of Chamaecyparis obtusa showed relatively strong antibacterial activities against Gram (+) bacteria and some fungi.

TL;DR: The blood pressure and heart rate fell dose-dependently in both the hypertensive and normotensive rats after intravenous injection of 1-125 mg/kg of HS, suggesting that HS possesses anti-hypertensive, hypotensive and negative chronotropic effects.

TL;DR: The alcoholic extract of the flowers of Calotropis gigantea was administered orally and explored for its analgesic activity in chemical and thermal models in mice and in acetic acid induced writhing test, an inhibition was observed at the doses of 250 and 500 mg/kg.

TL;DR: The antimicrobial activity of hydroalcoholic extracts of four Berber is species viz.

TL;DR: The antimicrobial activity against fish bacterial pathogens of flavonoids isolated from the leaves of Psidium guajava was evaluated and were shown to have bacteriostatic effect on all the tested bacteria.

TL;DR: A screening was conducted with 26 plants collected in the Brazilian southeast region, to identify plant extracts with antibacterial properties against Aeromonas hydrophila, Bacillus subtilis, Pseudomonas aeruginosa and Staphylococcus aureus, and it was observed that 13 of the tested extracts showed antibacterial activity.

TL;DR: Methanol extracts were prepared from different parts of 18 plants collected in the Yucatan peninsula and evaluated in an in vitro bioassay for leishmanicidal activity against Leishmania mexicana promastigotes.

TL;DR: Oral administration of the ethanolic extract and its fractions of the aerial parts of Cleome rutidosperma produced significant analgesic activity in acetic acid-induced writhing and tail immersion tests, anti-inflammatory effect against carrageenin induced inflammation and adjuvant induced polyarthritis and antipyretic activity against yeast-induced pyrexia.

TL;DR: The most effective essential oil against both lice and mites was tea tree oil; lavender was the second most effective, and lemon oil the least, although it did show activity against mites, unlike lice.

TL;DR: Extracts of 32 plants from the Brazilian northeastern semi-arid region called Caatinga were evaluated through DPPH radical scavenging assay, beta-carotene bleaching, and brine shrimp lethality tests (BST) and the highest activities were observed for Passiflora cincinnata, Chamaecrista repens, and Leonotis nepetifolia.

TL;DR: The bioassay-guided purification of the bioactive hexane fraction resulted in the isolation and identification of the naphthoquinone plumbagin as one of the metabolites responsible for the biological activity.

TL;DR: The potential antihypertensive activity of Brazilian plants was evaluated in vitro by its ability to inhibit the angiotensin-converting enzyme (ACE), and the following plants presented significant ACE inhibition rates.

TL;DR: Composition of the water-distilled oil of the aerial parts of Centaurea aladagensis, endemic in Turkey, was analysed by GC-MS and hexadecanoic acid, caryophyllene oxide and hexahydrofarnesyl acetone were found as main constituents in the oil.

TL;DR: Crude methanol and water extracts of 36 plants, employed in the treatment of diseases of probable bacterial etiology by the Venda people, were screened for antibacterial activity and Combretum molle, Peltophorum africanum, Piper capense, Terminalia sericea and Zanthoxylum davyi were the most active.
