Naphthoquinones of arnebia tinctoria [Forssk]

Phytochemical investigation of the light petroleum extract of Arnebia tinctoria Forssk. [=tetrastigma] root showed the isolation of two naphthoquinones: Alkannin and isovalerylalkannin. The structures of the two quinones have been established by UV, IR, HNMR and MS analysis. In addition, the aforementioned extract exhibited antimicrobial activity against Gram-positive and Gram-negative bacteria as well as fungal species

pharmacognostical study of fumaria parviflora lam. growing in Egypt. Part1: Root and stem

A pharmacognostical study comprising macro- and micromorphological investigation, preliminary phytochemical screening proximate analysis and TLC investigation of successive extractives of root and stem of Fumaria parviflora Lam. growing in Egypt is presented. Macro- and micromorphological characteristics were found diagnostic and helpful in identity of both organs as well as in differentiating them from other closely related species both in the entire and powdered forms

pharmacognostical study of fumaria parviflora lam. growing in Egypt. Part 2: Leaf and fruit

A pharmacognostical study comprising macro- and micromorphological investigations, preliminary phytochemical screening, proximate analysis and TLC investigation of successive extractives of leaf and fruit of Fumaria parviflora Lam. growing in Egypt is presented. Macro- and micromorphological characteristics were found diagnostic and helpful in identifying both organs as well as differentiating them from other closely related species both in the entire powdered forms

pharmacognostical study of fumaria parviflora lam. growing in Egypt. Part III: Flower

Macro- and micromorphological investigation, preliminary phytochemical screening, proximate analysis and TLC investigation of successive extractives of the flower of Fumaria parviflora Lam. growing in Egypt are presented. Macro- and micromorphological features as well as proximate analysis data of the flower are diagnostic and helpful in its identification as well as differentiation from other organs of the plant both in the entire and powdered forms
