Abstract
Russelia equisetiformis (Schlecht. & Cham.) is a multi-branching plant with graceful, arching stems and an overall fountain-like habit.A macromorphological study of the shape of the parts of the plant was carried out, and a study of the DNA of the mother plant DNA was compared to the plant tissues resulting from tissue culture using Inter Simple Sequence Repeatstechnique to distinguish between them. The initial phytochemical survey of the plant showed carbohydrates and / or glycosides, flavonoids, sterols and / or triple tannins and tannins along with a very small amount of volatile components as well as sterols and / or triterpene and while coumarin, cardiac glycosides, alkaloids and / or nitrogenous bases and saponins were present in small quantities.A study of the lipid content was carried out and the GLC analysis of unsaponifaiable matter (USM) of the aerial parts revealed the presence of 12 compounds andÜ-sitosterol (23.47%) was found to be the major compound while GLC analysis of fatty acids of the aerial parts revealed the presence of 13 compounds and Palmitic acid (45.28%) was found to be the major compound.The isolated volatile content was analyzed using GC/ MS and revealed 20 components and the major component were sclareol (17.65%).The total flavonoid content was evaluated according to the colorimetric assay and the total flavonoid content of the upper parts, flowers and roots (47.51.250) was equivalent to the kaempferol per 100 g dry powder, respectively, and the total phenolic content of the aerial parts of the plant, flowers and roots (1390, 440, 414) was equivalent to gallic acid per 100 g dry powder, respectively
