A systematic review on ethnobotany, phytochemistry, and pharmacology of R. Br. (Boraginaceae), a medicinal plant.

For the first time, critical review on R. Br. (Boraginaceae) is established.

Facile synthesis of a 3D magnetic graphene oxide/FeO/banana peel-derived cellulose composite aerogel for the efficient removal of tetracycline.

Many initiatives have incorporated graphene oxide (GO) and biomass into aerogels for wastewater treatment. We report on the facile fabrication of a magnetic GO/FeO/banana peel-derived cellulose (bio-cellulose) aerogel using an ultrasound-assisted mechanical mixing method and freeze-drying technique for the removal of tetracycline (TC). The component materials and composite aerogel were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), Raman spectroscopy, field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), nitrogen adsorption-desorption analysis, and vibrating sample magnetometry (VSM).

Morusacerane: A new gammacerane triterpenoid from the trunk of linn. with -glucosidase inhibitory activity.

This phytochemistry investigation on the trunk of L. resulted in the isolation of three triterpenoids, including a new gammacerane triterpenoid - morusacerane (); along with two known compounds of betulinic acid () and ursolic acid (). The structure elucidation was thoroughly conducted based on 1D, 2D-NMR and HRESIMS spectra, followed by a comparison with existing literatures.

Two new phenolic compounds from the Vietnamese lichen .

Chemical investigation of the lichen (Nyl.) Hale led to the isolation of two new phenolic compounds, 2-ethylhexyl orsellinate () and tinctorinone (). The structures were determined by analysis of their MS and NMR data as well as by comparison with literature data.

Camera-trap evidence that the silver-backed chevrotain Tragulus versicolor remains in the wild in Vietnam.

In an age of mass extinctions, confirming the survival of lost species provides rare second chances for biodiversity conservation. The silver-backed chevrotain Tragulus versicolor, a diminutive species of ungulate known only from Vietnam, has been lost to science for almost three decades. Here, we provide evidence that the silver-backed chevrotain still exists and the first photographs of the species in the wild, and urge immediate conservation actions to ensure its survival.
