Phytochemical and biological study of vangueria edulis cultivated in Egypt

Fractionation and purification of the alcoholic extract of the leaves and stem -bark of Vangueria edulis cultivated in Egypt afforded thirteen compounds identified as: p-sitosterol acetate [1], stigmasterol [2], palmitic acid [3], scopoletin [4], p-coumaric acid [5], protocatechuic acid [6], esculetin [7], ethyl I-O-glucosyi-4-O-[E] caffeoyl quinate [8], kaempferol 3-O-rhamnoside, 7-O-rutinoside [9], p-sitosterol [10], ceryl alcohol [11], vanillic acid [12] and p-sitosterol-3-Q-beta-D-glucopyranoside [13]. Identification of these compounds has been established by physical, chemical and spectral data as well as comparison with authentic samples. Compounds 8 and 9 are firstly reported from a natural source while the rest of the compounds have been isolated for the first time from the genus Vangueria. The LD[50] antibacterial antifungal anti-inflammatory, antipyretic and the effect on CNS were studied

Minor constituents from rubia cordifolia L. root

Reinvestigation of the chloroform soluble fraction of the chloroform-methanol [1:1] extract of the dried roots of Rubia cordifolia L. using different chromatographic techniques led to isolation of one new naphthohydroquinone dimer [1] and four known compounds identified as 3-friedelinol [2], atraric acid [3], vanillic acid [4] and D-beta-O-methoxy-chiro-inositol [5]. The identification of the isolated compounds was carried out using different physical, chemical and spectral methods of analysis

Phytochemical and biological study of Eranthemum nervosum [Vahl] R. BR., cultivated in Egypt

Fractionation and purification of the methanolic extract of the aerial parts of Eranthemum nervosum [Vahl] R. Br. [Acanthaceae] cultivated in Egypt yielded eleven compounds named: beta- amyrin [1], alpha-amyrin [2], Lupeol [3], beta-sitosterol [4], Apigenin [5], Kaempferol [6], beta-sitosterol 3-O-beta-D-glucopyranoside [7], Benzoic acid [8], Kaempferol-3-O-beta-D-glucopyranoside [9], Syringin [10] and Apigenin 7-O-neohesperidoside [11]. Identification of these compounds has been established by physical, chemical and spectral data as well as comparison with authentic samples. The LD50; anti-inflammatory; antipyretic; hepatoprotective and the effect on CNS were studied

Flavonoids and phenylpropanoids from spathodea campanulata P. beauvais leaves

Fractionation and purification of the merhanolic extract of the leaves of Spathodea campanulata P. Beauvais cultivated in Egypt afforded six compounds identified as: 1-O-caffeoyl-beta-D-glucopyranoside [1], kaempferol 3-O-[2-O-beta-D-xylopyranosyl]-beta-D-gaiacto-pyranoside [2], kaempferol 3-O-[6-O-alpha-L-rhamnopyranosyl]-beta-D-galactopyranoside [3], acteoside [4], kaempferol 3-O-[6-O-alpha-L-rhamnopyranosyl]-beta-D-gtucopyranoside [5] and quercetin 3-O-[2-O-beta-D-xylopyranosyl]-beta-D-galactopyranoside [6]. The structures of the isolated compounds were determined by physical, chemical and spectroscopic methods. All these compounds have been isolated for the first time from the genus spathodea

Macro- and micromorphological study of the leaf, stem and inflorescence of eranthemum nervosum T. anders [fam. Acanthaceae], cultivated in Egypt

Many ornamental plants belonging to the family Acanthaceae, showed interesting medicinal activities in treating: cough, chronic bronchitis, rheumatism, jaundice, ear troubles and fever. In addition to treatment of some skin diseases. In the present work, the detailed macro- and micromorphological characters of the leaf stem and inflorescence of Eranthemum nervosum T. Anders family Acanthaceae, were studied with the aim to find out the diagnostic elements of these organs, which facilitate their identification in both entire and powdered forms
