the presence of tribolium castaneum (herbst) in a stored food results in contamination and substantial economic damage due to loss of the products and a decrease in nutritional value. this study was conducted to determine the pesticidal and pest repellent activities of roots of laportea crenulata gaud. against t. castaneum. pesticidal activity was determined using surface film method, whereas, ...

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...

Abstracts: nanoparticles. All the extracts were used separately for the synthesis of gold nanoparticles through the reduction ofaqueous AuClgold ions to gold nanoparticles. The ethanol extract of black tea and its tannin free ethanol extract produced goldnanoparticles in the size ranges of 2.5-27.5 nm and 1.25-17.5 nm with an average size of 10 nm and 3 nm, respectively.The prepared colloid gol...

The present study was designed to assess the cytotoxicity, anti-inflammatory and analgesic properties of methanol extract of Woodfordia fruticosa flowers. Cytotoxic activity of methanol extract of Woodfordia fruticosa flowers was tested using Artemia salina (Brine shrimp) bioassay. Two doses (400 and 600 mg/Kg) were evaluated for the anti-inflammatory activity against the carrageenan, histamine...

hydroalcoholic extract (70% ethanol extract) of tubers of momordica tuberosa cogn. (cucurbitaceae) was subjected to preliminary phytochemical screening by qualitative tests. nitric oxide scavenging activity was performed by griess reagent method. and nephroprotective activity was assessed in gentamicin, cisplatin and paracetamol induced renal damage in wistar rats (150-200 g) by standard method...

The article describes the qualitative analysis of ethanol extracts from St. John's wort, cinnamon bark, rosemary leaves, lavender flowers, and ginger rhizomes, and the extract of their mixture using the method of high pressure liquid chromatography in order to identify flavonoids. The aim of the study was to identify the amounts of rutin, hyperoside, quercetin, and other flavonoids in the multi...

The aim of this study is to examine possible antioxidant and antiproliferative activities of the different extracts from sweet potato (Ipomoea batatas [L.] Lam ‘Tainong 57’) organs. DPPH staining, total phenolic compounds and flavonoid content, DPPH radical, reducing power method, FTC method, and cell proliferation were all employed. In the DPPH staining, ethanol extract of vein had the highest...

Indicum has 2 variations, especially in terms of flowers, namely elongated and rounded types with antioxidant effects. So the aim this research is to know C. leaves, one varieties Banjar, Banjarbaru Tanah Laut areas, that variety indicum varr.M. Antioxidant testing using TLC quantitative UV-Vis spectrophotometer. The results qualitatively have activity marked by a yellowish white stain. test 97...
