BACKGROUND Saraphi (Mammea siamensis) is a Thai traditional herb. In this study, the cytotoxic effects of crude ethanolic and fractional extracts including hexane, ethyl acetate, and methanol fractions from M. siamensis flowers were investigated in order to determine their effect on WT1 expression in Molt4 and K562 cells and Bcr/Abl expression in K562 cells. MATERIALS AND METHODS The flowers ...

BACKGROUND Tuberculosis, caused by Mycobacterium tuberculosis (MTB), is the most notified disease in the world. Development of resistance to first line drugs by MTB is a public health concern. As a result, there is the search for new and novel sources of antimycobacterial drugs for example from medicinal plants. In this study we determined the in vitro antimycobacterial activity of n-Hexane sub...

Hexane, acetone, and methanol extracts from Gnidia kaussiana Meisn (Thymeleaceae), each at two dosages (0.2 and 1 ml/50 g grains corresponding, respectively to 1 and 5g/kg), and neem seed oil (NSO), used as standard insecticide were evaluated for repellence, toxicity to Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae) adults, F1 progeny inhibition, persistence and as grain protectant d...

Gas chromatography-mass spectrometry and nuclear magnetic resonance spectroscopy were used to study the metabolism of deuterated n-alkanes (C6 to C12) and 1-13C-labeled n-hexane by a highly enriched sulfate-reducing bacterial culture. All substrates were activated via fumarate addition to form the corresponding alkylsuccinic acid derivatives as transient metabolites. Formation of d14-hexylsucci...

The study of aliphatic compounds adsorption on activated carbon can be carried out from the energetic change involved in the interaction; the energy values can be determined from isotherms or by the immersion enthalpy. Vapor phase adsorption isotherms of hexane at 263 K on five activated carbons with different content of oxygenated groups and the immersion enthalpy of the activated carbons in h...

Lack of data on safety of herbal medicines have endangered human health and life. The present study evaluated the genotoxic and mutagenic effect of Kalanchoe laciniata to access the safety and usefulness of the medicinal plant. Aqua-methanolic and n-hexane extracts of K. laciniata were evaluated for the genotoxic potential using Ames assay and cytotoxicity was evaluated using MTT assay. Ames as...

dracocephalum kotschyi boiss, a member of labiatae family, is a native plant to iran, which has been reported to have immunomodulatory, antihyperlipidemic and antispasmodic activities. the objective of this research was to study the antispasmodic and antidiarrhoeal activities of hydroalcoholic and hexane extracts of d. kotschyi in mice. furthermore, the antidiarrhoeal and antispasmodic effect o...

Solanum anomalum Thonn. ex Schumach. (family Solanaceae), an edible shrub whose fruits and leaves are used medicinally to treat diseases including diabetes was evaluated for effect on alpha amylase glucosidase enzymes in vivo. The leaf extract (70-210 mg/kg) fractions (hexane, dichloromethane, ethyl acetate, methanol, 140 of S. were vivo inhibitory using starch, sucrose maltose as substrates. A...

Background: Clinacanthus nutans (C.nutans) is a plant consumed as a cancer treatment in tropical Asia. Despite the availability of numerous anecdotal reports, evaluation of active anticancer effects has remained elusive. Therefore we here examined antiproliferative, reactive oxygen species (ROS)-inducing and apoptosis mechanisms of whole plant extracts in different cancer cell lines. Methods: A...

Chloropinane and chloromenthene, synthesized from pinene limonene, respectively, were compared with their non-halogenated analogs n-hexane for ability to solubilize natural products of interest such as ?-carotenoids, vanillin, rosmarinic acid. was six times more efficient than hexane ?-carotene solubilization. Chloromenthene 15 better hexane. Vanillin 20 soluble in chloropinane chloromenthene 3...
