Constituents of Plants Growing in Qatar, Part XXVI: Phytochemical investigation of Rumex vesicarius

Abstract

The study of Rumex vesicarius revealed the isolation and identification of four anthraquinones (chrysoplanol (I), emodin (II), physcion (III) and rhein (IV) and seven flavonoids (apigenin (V), isoorientin (VI), isovitesin (VII), luteolin (VIII), orientin (IX) quercitin (X) and viexin (XI. The study of the lipid fraction resulted in the isolation of a sterol fraction (beta-sitosterol, stigmasterol, campesterol and cholesterol) and a hydrocarbon fraction (mixtures from n-C12 to n-C32). The fatty acids were identified as hexanoic, octanoic, nanonoic, undecanoic, dedecanoic, tridecanoic, myristic, pentadecanoin, plametic, palmitoleic, heptadecanoic, stearic, linoleic, linolienic and arachdic acids.
