The resin glycosides from the sweet potato (Ipomoea batatas L. LAM.).
Four new and two known ether-soluble resin glycosides were isolated from popular sweet potato (the roots of Ipomoea batatas L. LAM., Kokei 14 go, Convolvulaceae) in Japan. Unlike ester-type dimers, batatins I and II, obtained from other sweet potato (Ipomoea batabas var. batatas), the glycosides were tetra or pentasaccharide monomers in which the sugar moieties are partially acylated by organic...
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...
متن کاملIsolation and Abiotic Stress Resistance Analyses of a Catalase Gene from Ipomoea batatas (L.) Lam
As an indicator of the antioxidant capability of plants, catalase can detoxify reactive oxygen species (ROS) generated by environmental stresses. Sweet potato is one of the top six most important crops in the world. However, its catalases remain largely unknown. In this study, a catalase encoding gene, IbCAT2 (accession number: KY615708), was identified and cloned from sweet potato cv. Xushu 18...
متن کامل[Screening of the anti-tumor active fraction from Ipomoea batatas Lam. (cv.simon) leaves].
OBJECTIVE Three fractions (SM, SM-A, SM-B) were prepared from different polarity parts of Ipomoea batatas Lam. (cv.simon) leaves and the anti-tumor potency as well as the dose-response relations were evaluated. METHODS The anti-tumor activities of fraction SM, SM-A or SM-B were screened by MTS in human hepatic cancer Hep3B cells, lung cancer A549 cells or gastric carcinoma MGC803 cells, respe...
متن کاملThree new pentasaccharide resin glycosides from the roots of sweet potato (Ipomoea batatas).
Three new pentasaccharide resin glycosides, batatosides III-V (1-3), were isolated from the roots of Sweet potato (Ipomoea batatas). Saponification of the crude resin glycoside mixture yielded substituents and simonic acid B. The structures of the isolated compounds (1-3) were established through spectroscopic analyses, including high field NMR spectroscopy and HR-ESI-MS, and chemical correlati...
