Isolation and Characterisation of Coumarin Derivative from Sida rhombifolia Linn.

2022
A novel coumarin derivative has been isolated from the dichloromethylene fraction of the aerial part of the Sida rhombifolia. The structure of the isolated compound has been established as 7-hydroxy-6-methoxy coumarin based on the spectral (UV, IR, 1HNMR, 13CNMR, mass) data.

Cyclopropenoid fatty acids in seed oils ofSida acuta andSida rhombifolia (malvaceae)

Journal of the American Oil Chemists' Society, 1976
AbstractSeed oils ofSida acuta andSida rhombifolia were found to contain sterculic (11.0, 10.8%) and malvalic (1.7, 2.0%) acids respectively, in addition to the normal fatty acids. Co‐occurrence of these acids was established by gas liquid chromatography of the silver nitrate‐methanol‐treated methyl esters usingSterculia foetida esters as a reference ...

Anti-arthritic activity of various extracts ofSida rhombifoliaaerial parts

Natural Product Research, 2009
Aerial parts of the plant Sida rhombifolia Linn. (Malvaceae) were extracted successively to produce various extracts. These extracts were screened for various parameters of anti-arthritic activity, such as adjuvant-induced arthritis, motor performance, mean distance travelled, and histopathological study.
