Abstract
Phytochemical screening of four plants named Plectranthus asirensis, Plectranthus ambinicus and Lavandula Pubescens Decne (all belong to Lamiaceae family) and Dorstenia Foetida belongs to Moraceae family, were studied qualitatively and quantitatively. Analysis of solvent extracts (ethanolic, methanolic, water and chloroformic) for each plant, have shown the presence of active components, but most of the components (alkaloids, tannins, glycosides, saponins, flavonoids, steroids and terpenoids) were found in the methanolic and ethanolic extracts, which may be due to their high polarity. The total quantitative content (%) of these active components was varied among the studied plants. Quantitative determination of vitamins K and C by HPLC and microtitration techniques respectively, showed that the content of the first, was low, while vitamin C was found in high amounts, specially in Plectranthus ambinicus plant, which imply that these plants can be an important source of natural antioxidants. Results of our study were compared with other published studies.
