Where it grows can affect the content of its compounds, this will also activity test being studied. This study used gaharu leaves from two different regions, namely Palembang and Bogor. The aim was to determine antioxidant Bogor total flavonoid content. research method began with sample preparation, simplicia characterization then extracted by maceration using 96% ethanol, fractionated liquid –...

One of these plants utilized in traditional medicine is Lactuca seriolla Linn., which belongs to the Asteraceae family. It goes by a variety common names world, including prickly lettuce, wild jagged and Kahu khas. The work aimed isolate characterize some bioactive constituent(s) from aerial part serriola utilizing Combiflash NEXTGEN high-performance liquid chromatography (HPLC). (aerial part) ...

The present investigation was carried out to explore the bioactive compounds from n-hexane fraction of methanolic extract quinoa (Chenopodium Willd.) roots. For this purpose, C. roots were collected, shade dried, and crushed into a fine powder. powdered material extracted in methanol, filtered, filtrate partitioned with n-hexane, followed by GC-MS analysis fraction. quantitative determination r...

The present study investigated the potential anticancer activity of the bark of Mangifera zeylanica, an endemic plant in Sri Lanka that has been traditionally used for cancer therapy. Cytotoxic and apoptotic effects were investigated in vitro using sulphorodamine assay, acridine orange and ethidium bromide staining, caspase-3 and -7 activity, DNA fragmentation and reverse transcription-quantita...

Plants extracted substances can constitute the best alternative to synthetic chemical insecticides and a good preservation of environment because they are biodegradables. The leaves Plectranthus glandulosus were with hexane, acetone methanol, then fractionated tested on adults Sitophilus zeamais Callosobruchus maculatus. Corn cowpea seeds each administered three (3) different doses (1, 5 10 g/k...

Sabicea species are used in the Amazon for treatment of fever and malaria, which suggests that its chemical constituents may have some effect on pain and inflammation. Phytochemical analysis of the hexane fraction obtained from the crude ethanol extract from Sabicea grisea var. grisea Cham. & Schltdl (Rubiaceae), an endemic plant in Brazil, resulted in the isolation of octacosanol. This study i...

In this study, modeling and thermodynamic analysis of the combined double flash geothermal cycle generation was conducted using zeotropic fluid as working in Organic Rankine Cycle (ORC). The performed based on first second laws thermodynamics. Hexane, cyclohexane, isohexane, R245fa, R236ea exhibit good performance at higher temperatures. three fluids—hexane, isohexane—were used. First, model re...

Avicennia marina (Avicenniaceae) is a species of mangrove tree used for treatment of small pox lesions in Persian folk medicine. The antiviral activity of methanol, ethanol, water, chloroform and n-hexane extracts was evaluated against HIV-1 and HSV. Methanol extract had the highest antiviral activity and the most polar fraction of this extract (fraction D) inhibited HSV with TI and SI values o...
