In order to evaluate the crude and processed Paeoniae Radix-Atractylodis Macrocephalae Rhizoma herbal pairs, a simple, easy, and sensitive high-performance liquid chromatography coupled with diode array detectors was developed for simultaneous determination of nine bioactive components in the herbal pairs. The calibration curve exhibited good linearity（r2≥0.9992）. The LODs and LOQs were ≤7.30 and 11.53 μg/m L, respectively. The intra-, inter-day and repeatability RSD values of the nine compounds were less than 3.86%, 2.71%, and 4.29%, respectively. The RSD stability values were less than 3.64%. The recovery of the method was in the range of 96.70%–102.10%, with RSD values less than 3.52%. The developed method can be applied to the intrinsic quality control of crude and processed Paeoniae Radix-Atractylodis Macrocephalae Rhizoma herbal pairs.展开更多

The homogeneity of AMP-1 was determined by HPLC and capillary electrophoresis that gave a single peak. AMP-1 is composed of galactose and mannose in a molar ratio of 1.0∶1.9. Its molecular weight is 3.8×10 3. The structure of glycan was elucidated by IR, 1H NMR, 13C NMR and methylation analysis, and on the basis of the results was suggested that AMP-1 contain a backbone of β-(1→2)-D-galactose residues with branches of single β-D-mannose residue being substituted at the O-6. Bioactivity assay of AMP-1 showed that it could inhibit growth of Sarcoma 180 and Lewis pulmonary carcinoma implanted in mice.展开更多
