ObjectiveTo analyze and determine the differential components of freeze-dried and sun-dried Panacis Quinquefolii Radix（PQR）， and to compare the differences in their pro-angiogenic activities. MethodFingerprints of freeze-dried and sun-dried PQR were established based on ultra performance liquid chromatography（UPLC）， and chemometrics methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were combined to determine the differential saponin composition of the two decoction pieces， and six representative saponins were selected and their contents in freeze-dried and sun-dried PQR were determined by UPLC. Transgenic zebrafish line Tg（fli1a∶EGFP） embryos fertilized for 24 h were selected， and different doses of 70% methanol extracts of freeze-dried and sun-dried PQR（10， 30 mg·L^-1） were used to intervene in normal zebrafish and in a zebrafish model of intersegmental vascular（ISV） injury induced by vascular endothelial growth factor（VEGF） receptor tyrosine kinase inhibitor Ⅱ（PTK787）， then the development of subintestinal vein（SIV） and ISV of zebrafish was observed， SIV diameter， mean number of crossings and mean number of germinations were determined， and the ISV vascular index was calculated， in order to compare the pro-angiogenic activities of the two decoction pieces. ResultThe similarity of the fingerprints of freeze-dried and sun-dried PQR decoction pieces was>0.950， and 17 common peaks were identified， of which 6 common peaks were designated as peak 6（ginsenoside Rg₁）， peak 7（ginsenoside Re）， peak 8（ginsenoside Rb₁）， peak 11（ginsenoside Rc）， peak 13（ginsenoside Rb₂）， and peak 16（ginsenoside Rd）， respectively. A total of 11 differential saponin components were screened by PCA and OPLS-DA， indicating that there were some differences in the contents of the components in the two decoction pieces. The results of determination showed that the contents of ginsenosides Rg₁， Re， Rb₁ and Rb₂ in freeze-dried PQR were higher than those in sun-dried PQR， while the contents of ginsenosides Rc and Rd were lower than those in sun-dried PQR（P<0.05， P<0.01）. In the study of the pro-angiogenic effect on normal zebrafish embryos， compared with the blank group， and the SIV vessel diameter， mean germination rate and mean crossover rate were significantly higher in the high-dose groups of freeze-dried and sun-dried PQR（P<0.01）， and the vessel diameter， mean numbers of crossings and germinations in the freeze-dried PQR group were higher than those of the sun-dried PQR group（P<0.05）. In the study of the pro-angiogenic effect on zebrafish embryos with ISV injury， the development of ISV in the model group was significantly inhibited when compared with the blank group， compared with the model group， different dose groups of freeze-dried and sun-dried PQR could promote the growth and sprouting of ISV， and the number of normal blood vessels in the freeze-dried PQR group was significantly higher than that in the sun-dried PQR group at the same dosage（P<0.05）. ConclusionFreeze-drying can effectively avoid the loss and secondary transformation of ginsenosides in PQR， and its angiogenic activity is better than that of sun-dried PQR， which can provide a reference for the production and development of high-quality PQR decoction pieces.

ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.
