From the hexane extract of the bark of the stems of Senna racemosa (syn. Cassia racemosa) a new dihydroanthracenone derivative, named racemochrysone, was isolated. Its structure was established as 8,9-dihydroxy-3-methoxy-2,2,6-trimethyl-(2H)-anthracen-1-one based on spectroscopical data, mainly 1D and 2D NMR experiments. In addition beta-sitosterol, stigmasterol, chrysophanol and physcion were ...

So-called ‘Saharanpur encephalitis,’ with high case fatality, used to occur annually, post-monsoon, in Western districts of Uttar Pradesh (UP). Over 2 decades, Indian Council of Medical Research (ICMR) and National Centre for Disease Control (NCDC) staff failed to diagnose it. A team of volunteer investigators (T Jacob John, virologist; VM Vashishtha, pediatrician; NC Nayak, pathologist; Amod K...

The objective of this study was to determine the coumarin content of ground cinnamon purchased from retail markets in the Czech Republic. No sample was labelled with information on the botanical source, but, in some cases, the countries of origin were specified. For comparison, a single cinnamon sample imported directly from a plantation in Sri Lanka that came from Cinnamomum verum was analyzed...

A n t i f u n g a l a c t i v i t y o f r h e i n ( 1 , 8 dihydroxyanthraquinone3carboxylic acid) isolated from the ethyl acetate extract of Cassia fistula flower was studied. Rhein inhibited the growth of many fungi such as Trichophyton mentagrophytes (MIC 31.25 μg/ml), Trichophyton simii (MIC 125 μg/ml), Trichophyton rubrum (MIC 62.5 μg/ml) and Epidermophyton floccosum (MIC 31.25 μg/ml).

The title compound, C(19)H(18)O(7), also known as chrysoobtusin, was isolated from Cassia tora L. (Leguminosae). The anthraquinone ring system is almost planar, the dihedral angle between the two benzene rings being 4.27 (4)°. The structure is stabilized by intra- and inter-molecular O-H⋯O and C-H⋯O hydrogen bonds, and by weak π-π stacking inter-actions along the b axis, with a centroid-centroi...

Powdery mildew on flowers of Cassia fistula and folioles Tamarindus indica, caused by Erysiphe quercicola, is reported for the first time in Brazil. The identity pathogen was confirmed morphological characteristics molecular sequence analyses ITS 28S rDNA regions. This report E. quercicola causing powdery C. T. indica

A study was conducted to determine the pathogens causing root rot, wilt and dieback disease of Cinnamomum cassia (Chinese cinnamon or cassia) in Vietnam, nurseries plantations Yen Bai, Quang Ninh, Thanh Hoa Nam provinces, streams Bai province. Pathogens were identified using morphology internal transcribed spacer (ITS) sequence analysis. The 204 isolates obtained included 125 Phytophthora 79 fr...
