OBJECTIVE To investigate the effect of Zizyphus spina christi leaf hydroalcoholic extract (ZLHE) on the isolated rat aorta. METHODS The rings of the endothelium intact and denuded thoracic aorta of Male and female Sprague Dawley rats were placed in Krebs-Henseleit solution to measure isometric contractile force. To study the involvement of voltage dependent L type calcium channels, concentrat...

In this study, three phenolic compounds were isolated from the seeds of Zizyphus spina-christi for the first time. The compounds were identified by means of 1 H-NMR-, UV and GC-MS as p-hydroxybenzoic acid, kaempferol, quercetin-3-O--L-rhamnosyl--D-glucopyranoside (rutin).

Mineral profile of tree leaves from eight local species (Acacia modesta, Albezia lebbeck, Capparis aphyla, Prosopes Juliflora, Tecoma undulata, Olea cuspidate, Ziziphus mauritiana and Ziziphus jujuba) was evaluated for feeding to sheep and goats. Leave samples were collected from three different locations (Surgul, Shakardara and Gumbat) in Kohat district of Khyber Pakhtunkhwa, Pakistan province...

This study was carried out to determine effects of different durations (20, 40, 60 days and control) of cold stratification treatments on seed germination and to overcome dormancy in seeds of twelve different drought tolerant plants. The species used in this study were Arbutus andrachne L., Cistus creticus L., Colutea armena Bois. Huet., Cotinus coggygria Scop., Cotoneaster numullaria Fisch. an...

Chinese jujube (Ziziphus jujuba Mill.) has long been widely used for human consumption and medicinal purposes in China. It has been reported to possess several vital biological activities. However, the systematic study on the chemical constituents absorbed into plasma and their metabolites is still insufficient. A high-performance liquid chromatography-photodiode array detector-electrospray ion...

The alcoholic extract of the bark of Zizyphus jujuba possesses antinociceptive, anticonvulsand and anti-inflammatory activities. The CNS depressant activity of the plant might be responsible, to some extent for these activities.

The so-called negritos adapt not just to a tropical forest environment but also to an environment characterized by perturbations and fluctuations. As with other hunter-gatherers in the region and, indeed, throughout the world, they use both social and ecological methods to enhance their chances of survival in this changing environment: socially, they have developed networks of trading and marri...
