Bioactive protopanaxatriol type saponins isolated from the roots of Panax notoginseng (Burk.) F. H. Chen.
Seven new protopanaxatriol type saponins, 20S-sanchirhinosides A1 (1), A2 (2), A3 (3), A4 (4), A5 (5), and A6 (6), and sanchirhinoside B (7) were obtained as minor constituents from the root extract of Panax notoginseng (Burkill, F. H. Chen), which showed protection effects against antimycin A induced mitochondrial oxidative stress. Their structures were elucidated by chemical and spectroscopic...
متن کاملDammarane-type triterpene saponins from the flowers of Panax notoginseng.
Four new dammarane-type triterpene saponins named floranotoginsenosides A (1), B (2), C (3) and D (4), together with five known triterpene saponins, were isolated from the flowers of Panax notoginseng. Their structures were elucidated on the basis of spectral and chemical evidence.
متن کاملMinor dehydrogenated and cleavaged dammarane-type saponins from the steamed roots of Panax notoginseng.
Nine new minor dehydrogenated and cleavaged dammarane-type triterpenoid saponins, namely notoginsenosides ST6-ST14 (1-9) were isolated from the steamed roots of Panax notoginseng, together with 14 known ones. Among them, 5-7 and 21-22 were protopanaxadiol type and the left 18 compounds, including 1-4, 8-20, and 23 were protopanaxatriol type saponins. Their structures were identified by extensiv...
متن کاملDetermination of Panax notoginseng Saponins
The feasible, reliable and selective multi-template molecularly imprinted polymers (MT17 MIPs) based on SBA-15 (SBA-15@MT-MIPs) for the selective separation and determination of the 18 trace level of ginsenoside Rb1 (Rb1), ginsenoside Rg1 (Rg1) and notoginsenoside R1 (R1) (Panax 19 notoginseng saponins, PNS) from biological samples were developed. The polymers were 20 constructed by SBA-15 as s...
متن کامل5,6-Didehydroginsenosides from the roots of Panax notoginseng.
Two minor novel dammarane-type saponins - 5,6-didehydroginsenoside Rd (1) and 5,6-didehydroginsenoside Rb1 (2) - were isolated from the dried roots of Panax notoginseng along with sixteen known saponins. The structures of the new compounds were elucidated on the basis of spectroscopic and chemical methods.
