A phytochemical study on the seeds of Cassia obtusifolia was carried out, which finally led to obtain two naphthalenes (1 and 2), two naphthopyrans (3 and 4) and twelve anthraquinones (5-16). The structures of all compounds were established mainly by NMR and MS experiments as well as the necessary
The present work aims to evaluate the anti-diabetic potentials of 16 anthraquinones, two naphthopyrone glycosides, and one naphthalene glycoside from Cassia obtusifolia via inhibition against the protein tyrosine phosphatases 1B (PTP1B) and α-glucosidase. Among them, anthraquinones emodin and
From leaves and pods of Cassia senna L. and C. angustifolia Vahl. were isolated the naphthalene glycosides 6-hydroxymusizin glycoside and the new tinnevellin glycoside. The structures were established mainly by spectroscopic methods ( (1)H NMR, (13)C NMR, MS).
Senna consists of the dried leaflets or fruits of Cassia senna (C. acutifolia) known in commerce as Alexandrian senna and of Cassia angustifolia commonly known as Tinnevelly senna. The senna plants are small shrubs of Leguminosae cultivated either in Somalia, the Arabian peninsula and near the Nile
The demand to develop efficient and reliable analytical methods for the quality control of nutraceuticals is on the rise, together with an increase in the legal requirements for safe and consistent levels of its active principles.To establish a reliable Differentiation of CASSIA SENNA and C. ANGUSTIFOLIA is possible by chromatographic identification of the naphthalene glycosides.
