A hexane extract of the flower-heads of Euryops pectinatus L. (Cass.) was formulated into local anti-inflammatory implantation patches with controlled release. Cross-linked sodium hyaluronate patches (F1-F3) and chitosan patches (F4-F6) were prepared by a casting/solvent evaporation technique. Morphological and mechanical characterizations including the components ratio, surfactant and the load...

Bioherbicides are an alternative to minimize the damage caused environment using agrochemicals. This study had objective of extracting neem oil from ripe waste fruits that Azadirachta indica A. Juss and optimizing process solvents (or a mixture solvents) with different polarities. Then, through solid-liquid extraction system (Soxhlet), hexane, methanol/hexane (1:1), ethanol, hexane/ethanol (1:1...

Diabetes mellitus is a symptom that can be characterized by chronic hyperglycemia and impaired metabolism of carbohydrates, fats and proteins associated with the lack of insulin secretion or insulin action both in absolute and relative terms. Treatment with drugs distributed on the market either relatively more expensive because of its use in the long term or have considerable side effects. Pre...

Bauhunia semibifida is among the several plants that have been studied for their medicinal properties. native to India. However, some species found in Africa. It has important uses, such as anti-bacterial, anti-inflammatory and anti-cancerous. This study aimed primarily at carrying out a preliminary phytochemical screening ascertain classes of bioactive compounds present solvent system(s) separ...

Dealumination of MCM-68 zeolite with MSE topology enhanced the selectivity to propylene (45-50%) and durability to coke formation during hexane cracking, regardless of the reaction temperature, which is attributed to the control of the position and density of acid sites originating from the framework Al atoms.

Objective: Fruits of lemon pepper (Zanthoxylum acanthopodium DC., Rutaceae) have been traditionally used as a spice and in folk medicine for treatment of diarrhea and stomachache. Stomachache could be associated with mycobacterial infection. The present study was designed to investigate the activity of Z. acanthopodium fruits against a non-infectious Mycobacterium smegmatis and to identify the ...

with 300 ml of ^2-hexane. The water-alcohol fraction was extracted twice with 300ml of CH2C12and the active CH2C12 extracts concentrated to yield 600mg. The extract was chromatographed on a silica gel column using hexane EtOAcas eluting solvent. Fractions with antitumor activity (280 mg) were eluted with w-hexane EtOAc 75 : 25. Column chromatography on silica gel was repeated and the activity (...
