چکیده
Alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction of the seeds of Quamoclit pennata BOJER (Convolvulaceae) provided five new glycosidic acids, quamoclinic acids B, C, D, E, and F, along with six organic acids, isobutyric, 2S-methylbutyric, tiglic, 2R,3R-nilic, 7S-hydroxydecanoic, and 7S-hydroxydodecanoic acids. These new compounds were characterized on the basis of spectroscopic data as well as chemical evidence. Quamoclinic acids E and F are the first examples of heptaglycosides of glycosidic acid.

Two new glycosidic acids, quamoclinic acids G and H, of the resin glycosides (Convolvulin) from the seeds of Quamoclit pennata.
Two new glycosidic acids, quamoclinic acids G and H, were isolated from the glycosidic acid fraction afforded by alkaline hydrolysis of the ether-insoluble resin glycoside (convolvulin) fraction from the seeds of Quamoclit pennata BOJER. Both compounds are the first examples of bisdesmosides of glycosidic acid having the sugar linkages at C-3 of 3,11-dihydroxytetradecanoic acid (ipurolic acid) ...
متن کاملThree new resin glycosides and a new tetrahydropyran derivative from the seeds of Quamoclit pennata.
Three new resin glycosides, quamoclins V (1), VI (2), and VII (3) and a new tetrahydropyran derivative, quamopyran (4), were isolated from the seeds of Quamoclit pennata BOJER (Convolvulaceae). The chemical structures of these compounds were determined primarily on the basis of spectroscopic data. The carboxyl group of the aglycone, 11S-convolvulinolic acid, of 1 and 2 was linked intermolecular...

متن کاملPhytochemical study of Swertia longifolia (Boiss.)
Plants of the genus Swertia (Gentianaceae) have been used in traditional medicine for many years. These herbs taste extremely bitter and have been mainly used for the treatment of hepatic, choleric and inflammatory diseases such as hepatitis, cholecystitis, pneumonia, osteomyelitis, dysentery, scabies, spasm, pain and neurastenia. In this genus, many components such as iridoids, xanthones, flav...
متن کاملEther-soluble resin glycosides from the roots of Ipomoea batatas.
Two new resin glycosides, batataosides I (1) and II (2), and five known compounds, friedelin (3), scopoletin (4), octadecyl caffeate (5), beta-sistosterol (6) and daucosterol (7), were isolated from the roots of Ipomoea batatas. Their structures have been determined based on the chemical and spectral data. Batataosides I and II have novel structures because the core simonic acid B was esterised...
