Anthraquinones from Vismia mexicana.
Vismia mexicana (Clusiaceae) is a small tropical tree found from Mexico to Honduras. The CH2Cl2/MeOH extract from the leaves has been reported to have inhibitory properties against reverse transcriptase of human immunodeficiency virus type 1 (HIV-1 RT). In order to characterize some of its chemical constituents, the EtOAc-soluble fraction of this extract was subjected to column chromatography. ...
متن کاملCapillary electrophoresis of anthraquinones from Cassia siamea.
The separation and determination of two anthraquinones, emodin and chrysophanol, and two bianthraquinones, cassiamin A and cassiamin B, were achieved by capillary electrophoresis (CE). The running electrolyte used in this method was 0.05 M hydroxypropyl-gamma-cyclodextrin in 0.1 M borate buffer (pH 9) containing 10% acetonitrile, with an applied voltage of 20 kV. Application of this technique i...
متن کاملStructure Antimutagenicity Relationship of Anthraquinones
Naturally occurring anti-mutagenic principles present in plants, human diet and other sources have protective effects against mutagens. Anthraquinones (AQs) considered one of the major plant phenolic pigments that contain many members, have evidenced the capability for inhibiting the mutagenicity toward Salmonella typhimurium of a number of mutagens. Not only genotoxicity/carcinogenesis is caus...
متن کاملHPLC Separation of Anthraquinones from Rhubarbs
Rheum species are medicinally important herbs, posses several type of biological activities due to the presence of anthraquinone derivatives. Several HPLC methods have been used for sepeatation of anthraquinone of Rheum Species. In most cases anthraquinones were separated using C18 column as a stationary phase, acetonitrile, water and methanol with or without acid as mobile phase at 1.0 ml/min ...
متن کاملAnthraquinones from the bark of Senna macranthera.
2-acetyl physcion (2-acetyl-1,8-dihydroxy-6-methoxy-3-methyl-9,10-anthraquinone, 2), a rare anthraquinone, was isolated from Senna macranthera var. nervosa (Vogel) H.S. Irwin & Barneby (Fabaceae). The chemical structure was elucidated and all (1)H and (13)C NMR chemical shifts were assigned by NMR one- ((1)HNMR, {(1)H}-(13)CNMR, and APT-(13)CNMR) and two (COSY, NOESY, HMQC and HMBC) dimensional...
