For along period of time, medicinal plants have played a vital role in the treatment of many diseases. The present study was carried out to evaluate phytochemical analysis of aqueous, methanol, ethanol, and chloroform crude extracts and antimicrobial screening of four Yemeni folk medicinal plants. The phytochemical analysis of the plant extracts revealed presence alkaloids, tannins, glycosides, saponins, flavonoids, steroids, terpenoids, vitamin K and vitamin C in all study plants. The antimicrobial activity of solvent extracts of Plectranthus asirensis, Plectranthus amboinicus Lavandula pubescens Decne, and Dorstenia foetida plants were inspected against the selected experimental pathogens such as K. pneumoniae, E. coli, S. epidermis, S. aureus, and C. albicans by agar well diffusion method. The results showed that extract from the investigated plants had antimicrobial activity in which ethanol and methanol extracts showed the highest values.
