1.Panajaponin, a new glycosphingolipid from Panax japonicus.
Guo Z;Zou K;Dan F;Wang J;Zhu S;Komatsu K Nat Prod Res. 2010;24(1):86-91. doi: 10.1080/14786410902999616.
Panajaponin, a new glycosphingolipid compound (1), together with eight known compounds, 28-glu-oleanolic acid ester (2), chikusetsusaponin IVa (3), chikusetsusaponin IV (4), ginsenoside Ro (5), ginsenoside Re (6), notoginsenoside R2 (7), ginsenoside Rg2 (8) and adenosine (9), was isolated from Panax japonicus, and the structures of all of the compounds were established on the basis of NMR and MS spectra.
2.Simultaneous determination of nucleobases, nucleosides and saponins in Panax notoginseng using multiple columns high performance liquid chromatography.
Qian ZM;Wan JB;Zhang QW;Li SP J Pharm Biomed Anal. 2008 Dec 15;48(5):1361-7. doi: 10.1016/j.jpba.2008.09.038. Epub 2008 Oct 1.
A new multiple columns HPLC method for simultaneous determination of 16 characteristic components, 5 nucleobases and nucleosides (uracil, cytidine, uridine, guanosine and adenosine), and 11 saponins (notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, notoginsenoside R4, notoginsenoside Fa, ginsenoside Rb1, notoginsenoside R2, ginsenoside Rg2, ginsenoside Rh1, ginsenoside Rd and notoginsenoside K), in the root of Panax notoginseng, a valued traditional Chinese medicinal herb, were developed. Notoginsenoside R4, Fa and K were first quantitatively determined in P. notoginseng. The 5 nucleobases and nucleosides compounds were separated on a Zorbax SB-Aq column (150 x 4.6 mm, 5.0 microm) and 11 saponins were analyzed using a Zorbax Bonus-RP column (150 x 4.6 mm, 5.0 microm) with column switching. The column temperature was set at 30 degrees C. Mobile phase was composed of 5mM ammonium acetate aqueous (A), water (B) and acetonitrile (C) using a gradient elution. The flow rate was 1.5 mL/min and detection wavelengths were set at 260 nm for nucleobases and nucleosides, and 203 nm for saponins. The developed method had good repeatability and sensitivity for quantification of 16 analytes with overall precision (including intra- and inter-day) less than 3% (RSD), and LOD and LOQ were less than 1.
3.Simultaneous determination of triterpene saponins in ginseng drugs by high-performance liquid chromatography.
Zhu S;Zou K;Cai S;Meselhy MR;Komatsu K Chem Pharm Bull (Tokyo). 2004 Aug;52(8):995-8.
A HPLC method for the simultaneous determination of 11 triterpene saponins with four-type aglycones (protopanaxadiol, protopanaxatriol, ocotillol and oleanolic acid types) in Ginseng drugs was developed and validated. Using a gradient of acetonitrile and 10 mM K-phosphate buffer (pH 5.80) as the mobile phase and UV detection at 196 nm, more than 18 ginsenosides with different aglycones were separated satisfactorily within 60 min. The detection limits (signal/noise> or =3) were 0.1 microg for ginsenosides Rb1, Rc, Rd, Re and Rg1, chikusetsusaponin III, and notoginsenoside R2, 0.2 microg for gisenoside Ro and chikusetsusaponin IVa, 0.3 microg for chikusetsusaponin IV, and 3 microg for majonoside R2. The calibration curve of each saponin had a correlation coefficient close to 1. Intra- and interday precisions were less than 2.1% (n=5) and 3.3% (n=15), respectively. The recovery rates of extraction were in the range of 96.4-102.7% for all ginsenosides. By adopting this method, the determinations of 11 ginsenosides in three Ginseng drugs derived from Panax ginseng, Panax vietnamensis var. fuscidiscus and Panax japonicus (Japan) were achieved.
