Vibrational assignment and structure of dibenzoylmethane. A density functional theoretical study.
Sayyed Faramarz Tayyari,H. Rahemi,Abdo-Reza Nekoei,Mansoureh Zahedi-Tabrizi,Yan Alexander Wang +4 more
TL;DR: The theoretical calculations indicate that the hydrogen bond in DBM is relatively stronger than that in BA and AA, and this result is in agreement with the vibrational and NMR spectroscopy results.

TL;DR: Phytochemical investigation of the stem bark of Beilschmiedia zenkeri led to the isolation of four new methoxylated flavonoid derivatives, which were evaluated in vitro for their antibacterial activity against three strains of bacteria and for their antiplasmodial activity against Plasmodium falciparum, chloroquine-resistant strain W2.
A Review on the Phytochemistry and Pharmacology of Genus Tephrosia
TL;DR: This review includes the chemical studies on different species mainly the isolation and identification of flavonoids, rotenoids and study of activity of some isolated compounds and also includes diffe-rent pharmacological activities like antioxidant, antimicrobial, anticancer, antiplas-modial, anti-inflammatory, larvicidal and toxicity studies of extracts and fractions.

Natural products from the genus tephrosia.
TL;DR: This review not only outlines the source, chemistry and biological evaluations of natural products from the genus Tephrosia worldwide that have appeared in literature from 1910 to December 2013, but also covers work related to proposed biosynthetic pathways and synthesis of some natural products.
Journal ArticleDOI
Tautomeric properties and gas-phase structure of acetylacetone.
TL;DR: The tautomeric and structural properties of acetylacetone have been studied by gas-phase electron diffraction (GED) and quantum chemical calculations (B3LYP and MP2 approximation with different basis sets up to aug-cc-pVTZ).

The chemistry of heterocyclic compounds
TL;DR: In this article, it was shown that one of the most common types of known quantities of phenyl phenyl is phenyl oxide (POP) oxide, which is a phenyl-oxyoxy phenyl (PE)-oxyoxyphenyl) that can be obtained from phenyl compounds.

Viridiflorin, an isoflavone from Tephrosia viridiflora☆
TL;DR: A new isoflavone, viridiflorin, has been isolated from Tephrosia viridispora and its structure was established as 4.5,5,7-trihydroxy-2.5′,5′-dimethoxy-6 prenylisoflavones based on spectral evidence and chemical transformation as discussed by the authors.

Flavanones fromTephrosia leiocarpa
TL;DR: In this article, the aereal parts of Tephrosia leiocarpa afforded two new flavanones, 5-hydroxy-7-methoxy-8-(3-hydrox-3-methyl trans -but-1-enyl)flavanone, named tephroleocarpin A and B, respectively.
