Evaluation of Analgesic and Anti-inflammatory Compounds from Stereospermum Kunthianum (bignoniaceae)
Stereospermum kunthianum (Bignoniaceae) is a woody shrub of the Sudano-Guinea savannah regions of Africa where the plant parts are used to treat various ailments including inflammatory conditions (rheumatoid arthritis) and pain. In continuation of our study of the anti inflammatory activity of this plant, we subjected the compounds previously isolated and characterized to pharmacological evalua...
متن کاملChemical constituents of Distictella elongata (Vahl) Urb. (Bignoniaceae).
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 ...
متن کاملAntiinflammatory Activity of Aqueous Extract of Stereospermum kunthianum (Cham, Sandrine Petit) Stem Bark in Rats
Stereospermum kunthianum, Cham, Sandrine Petit (family: Bignoniaceae) is used in traditional medicine to treat bronchitis, pneumonia and coughs, gastritis, wounds, rheumatic arthritis, ulcers, dysentery, leprosy and venereal diseases in humans. The antiinflammatory activity of the aqueous extract of the stem bark was investigated with experimental animal models using the carrageenan-induced paw...
متن کاملDimethoxyflavone isolated from the stem bark of Stereospermum kunthianum possesses antidiarrhoeal activity in rodents.
This study was undertaken to evaluate the antidiarrhoeal activity of 3, 7, 4'-trihydroxy-3'-(8″-acetoxy-7″-methyloctyl)-5, 6-dimethoxyflavone, a flavonoid isolated from the stem bark of Stereospermum kunthianum. The antidiarrhoeal activity was evaluated using rodent models with diarrhoea. The normal intestinal transit, castor oil-induced intestinal transit and castor oil-induced diarrhoea tests...
متن کاملBioactive Chemical Constituents from the Brown Alga Homoeostrichus formosana
A new chromene derivative, 2-(4',8'-dimethylnona-3'E,7'-dienyl)-8-hydroxy-2,6-dimethyl-2H-chromene (1) together with four known natural products, methylfarnesylquinone (2), isololiolide (3), pheophytin a (4), and β-carotene (5) were isolated from the brown alga Homoeostrichus formosana. The structure of 1 was determined by extensive 1D and 2D spectroscopic analyses. Acetylation of 1 yielded the...
