In this report, we present the results of the microscopy, seasonal variations and spectrophotometric estimation of hydroxy-anthraquinone glycosides of culitivated Cassia fistula Linn. The total glycoside contents ofthe morphological parts of this species at different stages of growth are also
The methanolic extract of the leaves of Cassia roxburghii DC., was investigated for its anthraquinone glycosides and antioxidant activity. Two new anthraquinone glycosides named emodin 1-O-β-D-glucopyranosyl-(1 → 2)-glucopyranoside (1) and aloemodin 8-O-β-D-glucopyranosyl-(1 → 6)-glucopyranoside (2)
Three new acetylated anthraquinone glycosides (1-3) were isolated from the seed of Cassia obtusifolia, together with one parent anthraquinone glycoside (1a). Their structures were determined on the basis of spectroscopic methods and physicochemical properties as obtusifoline-2-O-β-d-2,
From the defatted seeds of Cassia marginata fam (Caesalpinaceae) two new anthraquinone glycosides have been isolated and characterised as physcion-8-O-alpha-L-xylopyranoside and emodin-8-O-alpha-L-arabinopyranoside.
The effects of water extracts from Cassia tora L. (WECT) treated with different degrees of roasting (unroasted and roasted at 150, 200, and 250 degrees C) on the oxidative damage to deoxyribose, DNA, and DNA base in vitro were investigated. It was found that WECT alone induced a slight strand
Seasonal variations and spectrophotometric determination of anthraquinones in cultivated Cassia podocarpa are presented. The study shows that combined anthraquinones are concentrated in the leaves at peak flowering (2.43%) and lowest in the bark (0.21%). Anthraquinone glycosides reached peak levels
BACKGROUND
Cassia angustifolia (Senna), used as a laxative, is a plant from the Fabaceae family. It includes hydroxyanthracene glycosides, also known as Senna Sennoside. These glycosides stimulate the peristalsis of the colon and alter colonic absorption and secretion resulting in fluid accumulation
As a component of our program that pertains to the isolation of antihypertensive agents derived from natural products, we screened the bioactivity of seeds from raw and roasted Cassia tora via angiotensin converting enzyme (ACE) inhibitory assays. We found that both of the MeOH extracts from the raw
Senna (Cassia angustifolia Vahl.) is a world's natural laxative medicinal plant. Laxative properties are due to sennosides (anthraquinone glycosides) natural products. However, little genetic information is available for this species, especially concerning the biosynthetic pathways of sennosides. We
Three anthraquinone glycosides, gluco-obtusifolin [11], gluco-chryso-obtusin [15], and gluco-aurantioobtusin [13], were found to be platelet anti-aggregatory constituents of seeds of Cassia obtusifolia. Various other anthraquinone analogues were also tested, and their structure-activity
