The current research was designed to evaluate the phytochemical
contents and antimicrobial activity of Arthrocnemum macrostachyum
(Moric) K. Koch, Suaeda pruinosa Lange and Kochia indica (Bassia indica)
(Wight) A. J. Scott belongsto Chenopodiaceae (Amaranthaceae) family. This
study revealed that in the case of A. macrostachyum the soil texture was clay
loam, in the case of S. pruinosa the texture of the soil was sandy clay loam,
while in K. indica the texture of the soil was loamy sand. S. pruinosa results
showed the highest contents of total phenolics, flavonoids, lipids,
carbohydrates and tannins in comparison with the remaining two plants,
while A. macrostachyum showed the highest total alkaloids content. HPLC
analyses resulted in, A. macrostachyum containing resorcinol, kaempferol
and quercetin, in case of S. pruinosa contain ferulic acid, quercetin,
kaempferol and resorcinol while, K. indica contain quercetin, kaempferol,
resorcinol and phenantherine. Diethyl ether extract of S. pruinosa showed the
highest antioxidant activity with scav % 95.25 followed by chloroform
extract of A. macrostachyum (90.07%). The plants' extracts give moderate
activity against Candida albicans, but in the case of Bacillus subtilis, S.
pruinosa showed the highest activity. Also, K. indica results showed certain
activity against Escherichia coli and Proteus Vulgaris
