Flavan-Benzofurans from : Their Intracellular Antioxidant Activity and Molecular Docking to Glutathione Reductase.

Phytochemical investigation of Buch.-Ham (Moraceae) leaves led to the identification of three of the rarely found flavan-benzofuranes named artocarpinol C (), 3--artocarpinol C (), and artocarpinol D () along with six known flavan derivatives. Thus, a total of six artocarpinols are now described.

Fluorescent molecular rotors as versatile in situ sensors for protein quantitation.

Accurate protein quantitation is essential for many cellular mechanistic studies. Existing technology relies on extrinsic sample evaluation that requires significant volumes of sample as well as addition of assay-specific reagents and importantly, is a terminal analysis. This study exploits the unique chemical features of a fluorescent molecular rotor that fluctuates between twisted-to-untwisted states, with a subsequent intensity increase in fluorescence depending on environmental conditions (e.

Yellow Twig (Nauclea orientalis) from Thailand: Strictosamide as the Key Alkaloid of This Plant Species.

Comprehensive phytochemical examination from different perspectives using preparative and analytical chromatographic techniques combined with spectroscopic/spectrometric methods of the so-called “yellow twig” Nauclea orientalis (L.) L. (Rubiaceae) led to the identification of 13 tryptamine-derived (=monoterpene-indole) alkaloids.

Insecticidal activity of isolated gingerols and shogaols from Roscoe rhizomes against spp. (Lepidoptera: Noctuidae).

The discovery of eco-friendly plant-based insecticides is currently booming in research with an attempt to replace synthetic chemical insecticides causing tremendous adverse effects. The present work studied the insecticidal potential of ginger, an important medicinal plant. Four crude extracts from rhizomes were evaluated for their contact toxicity against second instars of , and using the topical application.
