pharmacognostical study of the Rhizomes and roots of Iris florentina L. cultivated in Egypt [part I]

Four isoflavonoids were isolated from the rhizomes and roots of Iris florentina L. and identified as irisflorentin [1], irisolone [2], irigenin [3], which were previously isolated from the plant [1] and 5-hydroxy, 8,4'-dimethoxy 7-0-isoflavone glucoside [4] isolated for the first time from I. florentina. Macro- and micromorphological characters of the rhizomes and roots were also studied in order to establish its diagnostic features in both entire and powdered forms

pharmacognostical study of Molucella laevis L.

The macro- and micromorphological characters of root, stem, leaf and flower of Molucella laevis L. [Lamiacae] are described and illustrated to facilitate their identification. The volatile oil of Molucella laevis L. was analyzed by capillary gas chromatography coupled to GC/MS. Forty-one components were identified. The major components of the oil were alpha-pinene [20.9%], pinocarvone [27%], methyl chavicol [20%] and trans-beta-caryophyllene [10%]

Investigation of malleable saccule LGrowing in Jordan

Dihydroimperatorin, marmesin and xanthoranol were isolated for the first time from Malabaila secacule L. [Umbelliferae]. The structure of these compounds were confirmed by using spectroscopic methods including UV, IR, PMR and mass spectra
