The tree and shrub species on a 16-ha watershed in the Coweeta Basin were sampled in 1984 and again in 1991 to determine the effects of drought on tree species composition and basal area growth. Mortality and radial growth were determined for tree species within three community types that represent a moisture gradient from moist to dry: covehardwoods > mixed-oak > oak-pine. Tree mortality from ...

The use of anthocyanin dyes extracted from epidermal leaves of Tradescantia spathacea (Trant) and petals of Ixora coccinea (IX) was evaluated in the application of dye-sensitized solar cells (DSSCs). Subsequently, cocktail anthocyanin dyes from these dyes were prepared and how they enhanced the cell's overall performance was assessed using five different volume-to-volume ratios. Cocktail dyes a...

Little leaf and yellowing symptoms associated with phytoplasma disease were observed in Pyracantha angustifolia Turkey. Amplification (through nested PCR) virtual restriction fragment length polymorphism (V-RFLP) confirmed the presence of symptomatic plants phylogeny based on R16F2n/R2 sequences P. was established sequence analysis showed that isolate had 98.7% similarity to ‘Candidatus Phytopl...

Non-toxic natural products employed in the formulation of cosmetics are of considerable interest. Recent efforts have focused on the identification of substances that inhibit tyrosinase activity (skin whitening properties) or suppress the formation of reactive oxygen species in skin cells (antiaging). In the present study, different parts of Ixora coccinea (IC) in various solvents were examined...

The diversifi ed genus Passifl ora is well distributed all over Brazil, and many species have been long used as medicinal plants, mainly against anxiety disturbances. This effect has been attributed to its rich fl avonoid composition. Flavonoids’ main class, fl avonoid glycosides, has presented central action, particularly as sedativehypnotic, anxiolytic and analgesic. The objective of the pres...

In this study, the analgesic, antipyretic and anti-inflammatory effects of the methanolic extract obtained from the leaves of Thunbergia coccinea Wall were investigated. Analgesic effect of MTC was evaluated by acetic acid –induced writhing, hot plate and tail flick method. Antipyretic activity of MTC was evaluated by yeast –induced hyperpyrexia in rats. The antiinflammatory activity was studie...

The active fraction (AF) from lxora coccinea flowers prevented the decrease in haemoglobin levels and leucocyte counts of Dalton's lymphoma tumour bearing mice, treated with cyclophosphamide (CYP). It also significantly increased the life span of tumour bearing mice, treated with cyclophosphamide. Serum glutamate pyruvate transaminase (SGPT) and serum alkaline phosphatase (SAKP) levels of tumou...
