The SPE-HPLC method was developed to determine an isosalipurposide (5) and its derivative, 6"-O-p-coumaroyl ester (6) in the bark of eight taxa (I-VIII) belonging to three species of the genus Salix and originating from a natural habitat or cultivated for pharmaceutical purposes. The chalcones were separated by HPLC under gradient elution with the concentration of ACN increasing from 20% to 50%...

Tropical stem-succulent trees store large quantities of water in their trunks yet remain leafless during the early and mid dry season. In contrast to most other tropical trees, bud break of vegetative buds is not induced in fully hydrated stem succulents between the winter solstice and the spring equinox by leaf abscission, abnormal rain showers or irrigation. Vegetative buds of leafless trees ...

Spraying disinfectants is one of the efforts to prevent transmission COVID-19. One high needs for can be overcome by using natural or those made from ingredients, such as use eco-enzymes. The problem that it takes 3 months produce eco-enzyme, so innovation able quickly. This research an experimental study with independent variables, namely composition organic waste (rambutan fruit skin, corn co...

BACKGROUND According to traditional Persian medicine (TPM) resources, the human digestive system includes four steps. In the first step, gastric digestion, the ingested food pours into the stomach and changes into the leachate called chylous due to the heat produced in the stomach. In the second step, hepatic digestion, the chylous enters in the liver through mesenteric vessels and transforms i...

Doubtlessly, wood identification is critically important for a number of sectors, including government organizations, the wooden-based industry, museums, law enforcement, and scientists working in fields botany, ecology, forestry, technology. Unfortunately, most species listed as “the least-known species” lack essential knowledge or even their anatomical feature basic properties to promote usag...

<span lang="EN-US">Machine orientation learning had demonstrated that deep (DL)-convolutional neural networks (CNNs) were robust image classifiers with significant accuracy. Although to been functional, DL scope classification as tight, well-defined possible uses a 2-class object, for instance, cats and dogs. The faced many challenges, e.g., variation factors, the intra-class variation. T...
