BACKGROUND The development of resistant to current antimalarial drugs is a major challenge in achieving malaria elimination status in many countries. Therefore there is a need for new antimalarial drugs. Medicinal plants have always been the major source for the search of new antimalarial drugs. The aim of this study was to screen selected Malaysian medicinal plants for their antiplasmodial pro...

BACKGROUND Kaempferia galanga is an important medicinal plant and has been traditionally used to help restlessness, stress, anxiety, depression etc. in tropics and subtropics of Asia including Bangladesh, India, China, Japan and Indochina. Literature survey revealed that there are very less reports on neuropharmacological activity of this plant. Therefore, the present study investigated the sed...

The aim of this study was to systematically evaluate the effect of the cultivation year on the quality of different ginseng tissues. Qualitative and quantitative analyses of ginsenosides were conducted using a UPLC-UV-MS method. Eight main ginsenosides in three tissues (leaf, rhizome and main root) and four parts (periderm, phloem, cambium and xylem) of ginseng aged from 1 to 13 years were dete...

BACKGROUND/AIMS There are limited therapeutic options available for irritable bowel syndrome with diarrhea (IBS-D). We tested the effects of Atractylodes japonica rhizome, a perennial plant native to North Asia, on both upper and lower gastrointestinal (GI) motility in guinea pigs. METHODS The extract of A. japonica rhizome was administered orally at different doses to test its effects on upp...

A study was carried on the mode of action and some properties of a cobra neurotoxin inhibitor found in the extract of Curcuma sp. (Zingiberaceae). When the principal postsynaptic neurotoxin (STX) of the Thai cobra (Naja naja siamensis) was mixed with an aqueous extract of Curcuma sp. rhizome, the STX was inactivated as tested in mice or in vitro using a rat hemidiaphragm preparation. The 'neuro...

Pteridium aquilinum is a ubiquitous species considered to be one of the plants most resistant to metals. This fern meets the demands for a good bioindicator to improve environmental control. Therefore, it was of interest to survey the accumulation of Cr and Ni in the rhizome and fronds of this species collected in Lower Silesia (SW Poland) of serpentinite rich in Cr and Ni and granite poor in t...

Eucodonia ‘Adele’ initiates seasonal shoot growth from a scaly rhizome. Larger rhizome segments (>2.5 cm) produced shoots at greater percentage compared with smaller segments. Shoots on larger were initiated sooner and had longer length. However, when formation efficiency was calculated as the number of potential per original stock rhizome, more efficient, producing three to four times many ...

Molineria latifolia (Singkut rhizome) is an endemic plant in tropical and humid climates, so it widely distributed several Asian countries. This study determines the antioxidant activity of rhizome ethanol extract isolated compounds. The a strong category with IC50 26.033 ppm. results isolation are known to contain 2,6-dimethoxy-benzoic acid 4-hexyl-2,5-dihydro-2,5-dioxo-3-furanacetic

Leaves and rhizome methanol extracts of Albertisia delagoensis tested positive against Plasmodium falciparum, with a very low cytotoxic activity in leaves against the Graham cell line.
