Pectolinarin, a flavone heteroside, was isolated from Distictella elongata (Vahl) Urb. leaves ethanol extract, along with a mixture of ursolic, pomolic and oleanolic acids, besides β-sitosterol. Their structures were established on the basis of spectral analysis (1H and 13C NMR, 1D and 2D) and they were compared with literature. This is the first report on the occurrence of this flavonoid in a ...

The present study was carried out to evaluate the antibacterial activities ofethanolicand aqueous extracts of Kigelia africana (Bignoniaceae) and Carica papaya (Caricaceae) against multi drug resistant Pseudomonas aeruginosa UTI causing pathogen. The bacterial sp was isolated from urine sample of UTI infected patient and identified with the help of colony characterization, gram staining and bio...

Tabebuia is one of the most commonly encountered genera of Bignoniaceae in the neotropics. Previous research has suggested that this genus may be paraphyletic and contain the tribe Crescentieae. Molecular sequence data of the chloroplast trnL-F and ndhF regions were used to reconstruct the phylogeny of Tabebuia, Crescentieae and related genera. A previously unrecognized clade of Neotropical, ar...

1. Subject and source Tecomella undulata (Smith) Seem. commonly known as`Rajasthan Teaka is one of the codominant species in the desert of western Rajasthan (Arya et al. have been reported from this plant. 3. Present study The concentrated petroleum ether extract prepared from the air dried leaves of T. undulata by Soxhlet apparatus, was chromatographed over a column of silica gel.

Tabebuia species (Bignoniaceae) have long been used in folk medicine as anti-inflammatory, antirheumatic, antimicrobial, and antitumor. The aim of this study was to investigate if aqueous extract from the leaves (AEL) of Tabebuia roseoalba (Ridl.) Sandwith, Bignoniaceae, and its constituents could be useful to decrease serum uric acid levels and restrain the gout inflammatory process. HPLC anal...

Lapachol whose isolation and study at the end of the century by Parternó, is one of the most brilliant chapters of Phytochemistry, especially in conjunction with the work of Max Siewert a communication on the wood of the Argentina Lapachol (Bignoniaceae) tree from Max Siewert, submitted along with Ricardo Napp in Exp. NAC. Philadelphia in 1876. The Lapachol has its origin in the Tabebuia avella...
