The expansion of C(3) shrubs into C(4)-dominated tallgrass prairies represents a fundamental shift in growth-form dominance accompanied by changes in resource acquisition and use. We assessed these changes by comparing the ecophysiological traits of the dominant C(4) grass Andropogon gerardii, with traits of three C(3) invasive shrub species, Cornus drummondii, Prunus americana, and Rhus glabra...

Extacts of root of Glycyrrhiza glabra linn were prepared by using n-hexan, toluene, tetrahydrofuran, ethylacetate, and ethanol and their antioxidant and antimicrobial activities were measured. Secondary metalbilites like flavonoids, alkaloids, terpenoids, glycosides, and steroids were measured and it was found that highly polar solvents ike ethyl alcohol, ethyl acetate and THF extract more meta...

Evolutionary radiations have been well documented in plants and insects, and natural selection may often underly these radiations. If radiations are adaptive, the diversity of species could be due to ecological speciation in these lineages. Agromyzid flies exhibit patterns of repeated host-associated radiations. We investigated whether host-associated population divergence and evidence of diver...

Waldheimia glabra is traditionally used as incense and as an anti-influenza drug by Tibetans in China. Here, we collected W. glabra from the Gangs Rinpoche mountain at an altitude of 5200 m, and analyzed its essential oil by gas chromatography-mass spectrometry (GC-MS) combined with the retention indices (RI). Twenty-seven compounds, representing 72.4% of the total essential oil, were identifie...

Efficacyand safety of a new herbal cream containing aqueous extracts of Azadirachta indica, Curcuma longa, Pongamia glabra, Glycyrrihiza glabra and Santallum album were evaluated in amulticentric, randomized, double-blind, placebo-controlled study. With active drug treatment, there was significant improvement in various signs like redness, oedema and symptoms like itching, burning, discharge an...

conclusions this study showed that topical glycyrrhiza glabra appeared to be a promising alternative in the treatment of olp. further studies should be conducted to assess the long-term effects of glycyrrhiza glabra. objectives the aim of this study was to compare the efficacy and safety of 1% glycyrrhiza glabra in orabase with 0.1% triamcinolone acetonide paste in treating oral lichen planus (...

Isolation of CYP72A154, a gene involved in glycyrrhizin biosynthesis pathway, Glycyrrhiza glabra L. (Iranian licorice)

licorice is obtained from glycyrrhiza glabra (g. glabra) in iran. glycyrrhizin is the main constituent of g. glabra and has several pharmacological effects. it is hydrolyzed to glycyrrhetic acid (ga) in the intestine after oral administration. in this study, a novel hplc method was used to determine the concentration of ga in rat plasma after oral administration of licorice aqueous extract. the...

the ecological potential assessment of forest sites introduces an index or indices that show the potential of forest site for fulfillment of special different roles of forest. khanikan forest at chalous needs precise investigation for assessment as indicator of lowland forests in forest ecosystems of northern iranwith considering its location position in caspian lowland and different values. th...
