Fingerprinting of Marsdenia tenacissima by capillary electrophoresis compared to HPLC.
Capillary electrophoresis (CE) is employed for the first time in a fingerprint analysis of Marsdenia tenacissima. Because the CE method is a new approach to fingerprinting, it is necessary to compare it to the conventional one: high-performance liquid chromatography (HPLC). In HPLC separation, 15 components are separated in 55 min, while in CE separation, 10 stable components are separated by 2...
متن کاملPregnane glycosides from the stems of Marsdenia tenacissima.
Four new pregnane glycosides, named marstenacissides A (1), B (2), C (3), and D (4), have been isolated from the stems of Marsdenia tenacissima. Their structures were established on the basis of chemical and spectral methods.
متن کاملMarstomentosides O-T polyoxypregnane glycosides from Marsdenia tomentosa.
Thirteen pregnane glycosides were isolated from fresh leaves of Marsdenia tomentosa collected in the Fukuyama district. Of these, six were glycosides previously obtained from the same plant collected in the Fukuoka district and one from another Asclepiadaceous plant. The structures of the six new glycosides were determined by spectrometric method.
متن کاملPolyoxypregnane Glycosides from the Roots of Marsdenia tenacissima and Their Anti-HIV Activities.
A continuous phytochemical study on the roots of Marsdenia tenacissima led to the isolation and identification of 13 new polyoxypregnane glycosides named marstenacissides B10-B17 (1, 2, 4, 7, 8, 11, 12, and 14) and marstenacissides A8-A12 (3, 9, 10, 13, and 15) in addition to two known polyoxypregnane glycosides marsdenosides M and L (5 and 6). Their structures were established by spectroscopic...
متن کاملStudies on the anti-angiogenic effect of Marsdenia tenacissima extract in vitro and in vivo
Marsdenia tenacissima, which is widely used as an anticancer herb in traditional Chinese medicine, has been shown to possess anticancer activities. However, the underlying molecular mechanism(s) involved in the anticancer effect of this herb are poorly understood. Angiogenesis is important in the development of cancer. The main features of angiogenesis are increased vasculature and overexpressi...
