  • This study was carried out to investigate inhibitory effect of extracts from the root of Paeonia lactiflora on postprandial hyperglycemia. Organic solvent (hexane, ethyl acetate, butanol, aqueous) extracts from the crude drug were fractionated by high performance liquid chromatography. These fractions were examined to evaluate ${\alpha}-glucosidase$ (EC 3. 2. 1. 20) inhibition by microplate colorimetric assay. Among the fractions examined, the ethyl acetate fraction from the roots of Paeonia lactiflora showed potent inhibitory effects on ${\alpha}-glucosidase$. Therefore, further fractionation of the fraction was carried out to isolate the active principles. Finally, we isolated and Purified 1,2,3,4,6-penta-O-galloyl-beta-D-glucose (PGG) as a active principle by activity-guided fractionation. These results suggest that the extract from the root of Paeonia lactiflora can be used as a new nutraceutial for inhibition on postprandial hyperglycemia and PGG might be a candidate for developing an ${\alpha}-glucosidase$ inhibitor.

  • We previously showed that the root extract of Paeonia lactiflora Red Charm might have anti-oxidant activities, however it was not clear which components might be involved in this activity. Our boinformatics analysis indicated the root extracts of Paeonia lactiflora Red Charm has a couple of potential anti-oxidant materials. One of them is paeoniflorin. We hypothesized that one of components present in Paeonia lactiflora Red Charm, paeoniflorin and its derivatives might be related to anti-oxidant activity. In this study, we compared paeoniflorin and its derivatives with the root extract of Paeonia lactiflora Red Charm using DPPH assays to measure its antioxidant activities. Paeoniflorin showed the highest radical scavenging activity(%) in $1000{\mu}g/m{\ell}$. its derivative showed the high levels radical scavenging activity(%) in $600{\mu}g/m{\ell}$, $800{\mu}g/m{\ell}$, $1000{\mu}g/m{\ell}$ similar to ascorbic acid. Taken together, these results suggest that Paeoniflorin and its derivatives may play a role in anti-oxidant acitivity in the root extracts of Paeonia lactiflora. Much of future studies may be needed to develop a potential new anti-oxidant candidates with anti-aging and anti-cancer effects.

  • Little attention has been paid to the functional aspect of the flower petal of Paeonia lactiflora, compared to that of its root. To determine the components of flower petal of Paeonia lactiflora, we conducted the Fourier transform ion cyclotron resonance (FT-ICR) MASS spectrophotometric analysis. We detected the 24 different types of ingredients from the 70% ethanol extracts of flower petal of peonia lactiflora cv. ‘Red Charm’. The main compounds were quercetin glucopyranosides, methyl gallate, paonioflolol and kaemperol glucopyranosides. We further tested its functional activity. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity of the extracts was 87.9-90.4% at 0.1mg/ml. This result showed that these flower extracts have approximately 5-fold stronger antioxidant potential than a previous report with root extracts (Bang et al. 1999). The result of tyrosinase inhibition assay of Paeonia lactflora extract was almost similar to that of arbutin except significantly higher effect in the coral sunset extract at 0.1% concentration. Hyaluronidase inhibition assay showed 76.5% inhibition at 5% concentration of this flower extract, indicating that Peaonia lactiflora flower extracts have the major anti-inflammatory, anti-oxidant and brightening effects. Taken together, these results suggest these three Paeonia lactiflora species extracts might provide the basis to develop a new natural brightening agent.

  • We previously showed that the root extract of Paeonia lactiflora might have anti-inflammatory effects. Paeoniflorin (PF) has been identified as one of the main bioactive components of Paeonia lactiflora, however its role has been well characterized. In this study, we tested whether PF and its derivatives, which is removed the hydroxy group from PF, might have anti-inflammatory effects. In the Nitric Oxide assay, PF and Paeoniflorin's derivative (PFD) showed 55% and 56% more anti-inflammatory effect, compared to LPS control, respectively at 250ug/ml. To further confirm, we examined the effect of PF on tyrosine phosphorylation of Erk MAP Kinase. It is well established that tyrosine phosphorylation of Erk MAP Kinase is related to NF-kB mediated inflammation pathway. We therefore examined whther PF and PFD might regulate Erk activity. PF and PFD showed 35% and 22% less tyrosine phosphorylation compared to Paeonia lactiflora Red Charm extract control, respectively at 500ug/ml. Taken together, these results suggest that PF and PFD may play a role in anti-inflammatory effects in the root extract of Paeonia lactiflora. This study will provide the basis to develop a platform for the inflammation-mediated diseases therapeutics in the near future.

  • The genus Paeonia belongs to the family Paeoniaceae having significant medicinal and ornamental importance. The present investigation was undertaken with an aim to understand phylogenetic relationships of three Paeonia species (P. lactiflora, P. obovata, and P. suffruticosa) that are widely distributed in China, Korea, and Japan, using nuclear ribosomal DNA (nrDNA) internal transcribed spacer (ITS) sequence and to compare the phylogeny results with investigations reported earlier using existed sequences of the same species. The size variation obtained among sequenced nrDNA ITS region was narrow and ranged from 722 to 726 bp. The highest interspecific genetic distance (GD) was found between P. lactiflora and P. suffruticosa or P. obovata. The phylogram obtained using our nrDNA ITS sequences showed non-congruence with previous hypothesis of the phylogeny between section Paeonia and section Moutan of genus Paeonia. This result was supported by the phylogenetic relations showed in the phylogram constructed with existed sequences in NCBI. The present study suggested that P. obovata belonging to section Paeonia was phylogenetically closer to P. suffruticosa representing section Moutan of genus Paeonia than P. lactiflora belonging to section Paeonia. The main reason of the paraphyly of section Paeonia is thought to be nucleotide additivity directly caused by origin hybridization. This study provides more sequence sources of genus Paeonia, and will help for further studies in intraspecies population, and their phylogentic analysis and molecular evolution.

  • The root of Paeonia lactiflora has been used in Chinese medicine. We conducted to check the comparative qualities of ethanol solvent extraction (PLE) and supercritical carbon dioxide extraction (PLS) of P. lactiflora root. PLE had higher antioxidant and polyphenol contents than PLS. But, PLS were significantly increased peroxisome proliferator-activated receptor (PPAR)-α. In addition, PLS inhibited the adipocyte differentiation of 3T3-L1 cells. When treated with the extract at a concentration of 100 ㎍/mL, the Wnt/β-catenin pathway reporter luciferase activity of HEK 293-TOP cells increased approximately by 3-folds compared to that of the untreated control group. These results indicate that P. lactiflora supercritical carbon dioxide extract may serve as a cosmeceutical for improving skin barrier function and the treatment of obesity.
