Mosquito larvicidal activity of aqueous extracts of long pepper (Piper retrofractum vahl) from Thailand.
Aqueous extracts of nine medicinal plants were bioassayed against larvae of Culex quinquefasciatus Say and Aedes aegypt (L.). Among these plants, the long pepper, Piper retrofractum Vahl (Piperaceae), showed the highest level of activity against mosquito larvae. To gain more information on larvicidal activity of P. retrofractum, fresh fruits of this plant were extracted in water and the extract...
متن کاملChemical Composition and Antimicrobial Properties of Piper ovatum Vahl.
The chemical composition of the essential oil obtained from the leaves of Piperovatum Vahl by hydrodistillation was analyzed by GC-MS. The main constituents found were delta-amorphene (16.5 %), cis-muurola-4(14),5-diene (14.29 %) and gamma-muurolene(13.26%). The crude extracts and isolated compounds were screened for their antimicrobial activity. Hydroalcoholic extracts of different parts of Pi...
متن کاملPiper retrofractum Vahl. Extract, as a PPARδ and AMPK Activator, Suppresses UVB-Induced Photoaging through Mitochondrial Biogenesis and MMPs Inhibition in Human Dermal Fibroblasts and Hairless Mice
Photoaging occurs by UVB-irradiation and involves production of reactive oxygen species (ROS) and overexpression of matrix metalloproteinases (MMPs), leading to extracellular matrix damage. Piper retrofractum Vahl. is used as a traditional medicine for antiflatulence, expectorant, sedative, and anti-irritant; however, its antiphotoaging effect has not yet been studied. The current study investi...
متن کاملRandom Forests Based Classification for Crops Ripeness Stages
This article presents a classification approach based on random forests algorithm for estimating and classifying the different maturity/ripeness stages of two types of crops; namely tomato and bell pepper (sweet pepper). The proposed approach consists of three phases that are pre-processing, feature extraction, and classification phases. Surface color of tomato and bell pepper is the most impor...
متن کاملEthnobotany of the genus Piper ( Piperaceae ) in Thailand
Thailand is located in the tropical rain forest zone above the equator. This geographically supports very rich biodiversity, including the genus Piper (Piperaceae). Thirtyeight species of Piper, from out of over 1,000 species in the world, have been discovered recently (1998-2006) by the authors. Plant morphology and plant use information were recorded via observation, market surveys, and inter...
