The leaves of 10 Cassia species (Leguminosae), cultivated in Nigeria, were assayed spectrophotometrically for combined anthraquinone content and also pharmacologically for their laxative properties in male albino rats using official senna leaves (Cassia acutifolia Del.) as the reference standard. Leaves of C. podocarpa Guill, and Perr. and of senna had identical laxative potency. The results of...

BACKGROUND AND AIM Cassia (C.) surattensis Burm. f. (Leguminosae), a medicinal herb native to tropical equatorial Asia, was commonly used in folk medicine to treat various diseases. The aim of the present study is to investigate the effects of methanolic flower extract of C. surattensis against Aspergillus (A.) niger. MATERIALS AND METHODS Antifungal activity of C. surattensis flower extract ...

Cissus rotundifolia (Forsk.) Vahl, a native to Africa and the Arabian Peninsula is recorded for the first time from the Peninsular India. A detailed description with illustration and relevant notes are provided for easy identification.

A water soluble galactomannan having D-Mannose [4-part] and D-Galactose [2-parts] was isolated from Cassia fistula. In cassia fistula Hydrolysis of methylated seed gum furnished three methylated sugars, 2, 3-di-O-methyl-D-mannose, 2, 3,6-tri-O-methyl-D-mannose and 2, 3,4,6-tetra-Omethy-D-galactose was present in molar ratio 3:2:1. Partial acid catalysed hydrolysis of the seed gum gave five olig...

Retinitis pigmentosa (RP) is an inherited photoreceptor-degenerative disease, and neuronal degeneration in RP is exacerbated by glial activation. Cassia seed (Jue-ming-zi) is a traditional herbal medicine commonly used to treat ocular diseases in Asia. In this report, we investigated the retina-protective effect of chrysophanol, an active component of Cassia seed, in an N-methyl-N-nitrosourea (...

The transmission spectra of bud scales of 14 woody species and the 77 K fluorescence emission spectra of the innermost leaf primordia of closed and opened buds of 37 woody species were studied. Pigment concentrations were determined in some species. Bud scales had low transmittance between 400 and 680 nm with a local minimum around 680 nm. Transmittance increased steeply above 680 nm and was > ...

This study is the first report to suggest a morphological phylogenetic framework for the seven varieties of Ficus deltoidea Jack (Ficus: Moraceae) from the Malay Peninsula of Malaysia. Several molecular-based classifications on the genus Ficus had been proposed, but neither had discussed the relationship between seven varieties of F. deltoidea to its allies nor within the varieties. The relatio...
