ISOLATION AND STRUCTURAL ELUCIDATION OF THE FIRST KNOWN C-HOMOPROTOBERBERINE
A novel C-homoprotoberberine alkaloid, Hediamine (2), has been isolated from the roots of Berberis actinucantha (Berberidaceae). Conclusive proof for the structure of hediamine was obtained by its comparison with the isomeric lactam (4), by chemical transformation, and by means of spectroscopic techniques (UV, IR, MS, NMR).
متن کاملPhytochemical Screening of Gum Extracted from Curcuma Amada
The aim of the present study is the phytochemical screening of gum of Curcuma amada (mango ginger). Natural gums are economic, easily available and found useful as tablet binder. The phytochemical properties of a gum obtained from the rhizomes of Curcuma amada were characterized by various test including test for Steroids, tannins, flavanoids, amino acids, carbohydrates and glycosides. All of t...
متن کاملIsolation and Structural Elucidation of Antiproliferative Compounds of Lipidic Fractions from White Shrimp Muscle (Litopenaeus vannamei)
Shrimp is one of the most popular seafood items worldwide, and has been reported as a source of chemopreventive compounds. In this study, shrimp lipids were separated by solvent partition and further fractionated by semi-preparative RP-HPLC and finally by open column chromatography in order to obtain isolated antiproliferative compounds. Antiproliferative activity was assessed by inhibition of ...
متن کاملIsolation of antimicrobial compounds from guava (Psidium guajava L.) and their structural elucidation.
Four antibacterial compounds were isolated from leaves of guava (Psidium guajava L.), and the structures of these compounds were established on the basis of chemical and spectroscopic evidence. Two new flavonoid glycosides, morin-3-O-alpha-L-lyxopyranoside and morin-3-O-alpha-L-arabopyranoside, and two known flavonoids, guaijavarin and quercetin, were identified. The minimum inhibition concentr...
