  • The present study was designed to evaluate the inhibitory effects of fermented Liriope platyphylla extract on the production of inflammation-related mediators (NO, ROS, NF-${\kappa}B$, iNOS and COX-2) and pro-inflammatory cytokines (TNF-${\alpha}$, IL-$1{\beta}$, IL-6) in lipopolysaccharide-stimulated RAW 264.7 macrophages. Freeze-dried Liriope platyphylla was fermented by Saccharomyces cerevisiae and extracted with 70% ethanol. In lipopolysaccharide-stimulated macrophage cells, the treatment with fermented Liriope platyphylla extract decreased the generation of intracellular reactive oxygen species dose-dependently and increased antioxidant enzyme activities, including superoxide dismutase, catalase and glutathione peroxidase. Fermented Liriope platyphylla extract also inhibited NO production in lipopolysaccharide-stimulated RAW 264.7 cell. The expressions of NF-${\kappa}B$, iNOS, COX-2 and pro-inflammatory cytokines were inhibited by the treatment with fermented Liriope platyphylla extract. Thus, this study shows the fermented Liriope platyphylla extract could be effective at inhibiting the inflammation process.

  • The antioxidative activities of beverages with water or ethanol extracts from Maegmundong (Liriope platyphylla) were investigated with free amino acid and mineral analysis, as well as saponin, total phenolics and flavonoid determination. Antioxidative activity was evaluated by electron donating ability and ABTS radical scavenging activity. There was only a small difference between water extract beverages and ethanol-extract beverages with respect to their electron donating ability and ABTS radical scavenging activity, although the total saponin, total phenolics and flavonoid were found to be greater in the ethanol extract beverages than in the water extract beverages. Three major free amino acids of the Magemundong beverages with water- or ethanol extract were asparagine (58.30, 60.68 mg%), methionine (15.10, 13.95 mg%, respectively) and proline (12.31, 14.00 mg%, respectively). The most abundant mineral in the Maegmundong beverage with water and ethanol extract was potassium (238.68, 244.32 mg%, respectively).

  • The ethanol extraction yield of Liriope platyphylla(Lp) was about 30.7% by extract apparatus. This study was done to investigate the carbohydrate metabolism related enzyme activities effects of Lp in streptozotocin (STZ)-induced diabetic rats. The contents of serum glucose, triglyceride (TG) were significantly decreaed in Lp treated group compared to the those of STZ-control group, also content of Total cholesterol was decreased. High density lipoprotein (HDL)-cholesterol was increased in Lp treated group. The activity of glucose-6-pase(G-6-Pase) was significantly decreased in Lp treated group. Also the activity of glucokinase(Gk) was increaed in Lp treated group. The content of hepatic glycogen was significantly increaed in Lp treated group. These results indicated that ethanol extract of Lp would have antidiabetic effect in STZ-induced diabetic rats.

  • Purpose : This study aimed to analyze the antibacterial activity of Liriope platyphylla ethanol extract (LPEE) against Streptococcus mutans and Porphyromonas gingivalis and to validate its potential for the prevention and treatment of dental caries, gingivitis, and periodontal disease. Methods : To verify the antibacterial effect of L. pulsatilla ethanolic extract (LPEE) against S. mutans and P. gingivalis, the disk diffusion method was used to determine the inhibition zones at concentrations of 50, 100, 200, and 300 mg/㎖. To determine the minimum inhibition concentration (MIC), the final dose of LPEE was .2, .4, .8, 1.6, 2.5, and 5.0 mg/㎖, and the minimum bactericidal concentration (MBC) was determined based on the MIC results. To confirm the growth inhibitory effect of LPEE on both pathogens, the absorbance was measured at 600 nm after each incubation for 0, 3, 6, 12, and 24 hr at concentrations of .8, 1.6, 2.5, and 5.0 mg/㎖. Results : The cytotoxicity of LPEE was evaluated and the cell viability was more than 70 % at 400 mg/㎖. Therefore, concentrations of 50, 100, 200, and 300 mg/㎖ were used in this study. The antimicrobial effect against S. mutans was seen at 100 mg/㎖ and grew in a concentration-dependent manner, while P. gingivalis was effective at 50 mg/㎖ with the dose dependency. The MIC was .8 mg/㎖ for both strains, and the MBC was 1.6 mg/㎖ with the same results. The growth inhibitory effect of LPEE on S. mutans and P. gingivalis was observed, even at low concentrations. Conclusion : The antibacterial effect of LPEE was evaluated through the analysis of MIC, MBC, and growth inhibition effect on S. mutans and P. gingivalis, which suggests LPEE might have the possibility of utilization as a preventive and therapeutic composition for oral diseases.

  • The roots of Liriope platyphylla (Liliaceae) are widely used in traditional Chinese medicine. In the present study, we investigated the effects of ethanol (70%) extract of the roots of Liriope platyphylla (ELP70) on learning and memory using behavioral and immunohistochemical methods in mice. Control animals were treated with vehicle (10% Tween 80). With sub-chronic treatments of ELP70 (p.o.) for 14 days, the latency time was significantly increased compared with that of the vehicle-treated control group (50, 100 and 200 mg/kg; P<0.05). Moreover, immunopositive cells for brain derived neurotrophic factor (BDNF) were significantly increased in the hippocapmpal dentate gyrus and CA1 regions after ELP70 treatments for 14 days (50, 100 and 200 mg/kg; P < 0.05). In addition, those cells for nerve growth factor (NGF) were also increased in the hippocapmpal dentate gyrus region (50, 100 and 200 mg/kg; P<0.05). These results suggest that the sub-chronic administration of ELP70 improves learning and memory, and that their beneficial effects are mediated, in part, by the enhancement of BDNF or NGF expression.

  • This study investegated the effect of Liriope platyphylla (LP) on allergic reactions and its mechanism of action. We investigated the effect of LP on Evans Blue (EB) extravasation induced by anti-dinitrophenyl (DNP)-IgE in rats. We tested whether the ethanol extract of LP reduced ear skin thickness and historical changes induced by topical application of 2,4-dinitrofluorobenzene (DNFB) to ears of mice. We evaluated compound 48/80-induced release of histamine in rats peritoneal mast cell (RPMCs). We also investigated the regulatory effect of LP on the level of inflammatory mediators in PMACI-induced human mast cell (HMC-1); cytokine IL-6, IL-8, TNF-${\alpha}$ in HMC-1, MAPKs (ERK, JNK and p38) in HMC-1. The ethanol extract of LP (81.3 mg/100 g body weight) significantly inhibited the PCA reaction compared with the control (P < 0.05). However, LP did not prevent topical applications of DNFB-induced ear skin thickening and histological changes. In RPMCs, histamine release induced by compound 48/80 was significantly attenuated by LP at $100{\mu}g/ml$ (P < 0.05). LP extract ($100{\mu}g/ml$) significantly reduced the PMACI-induced IL-6, IL-8, and TNF-${\alpha}$ secretion via inhibition of ERK phosphorylation in HMC-1. In conclusion, the ethanol extract of LP inhibited mast cell-derived, immediate-type allergic reactions, and the result suggest the potential of LP for preventing allergic inflammatory disorders.

  • Background: Saengmaeksan (SMS) is a traditional Korean medicine composed of three herbs, Panax ginseng, Schisandra chinensis, and Liriope platyphylla. SMS is used to treat respiratory and cardiovascular disorders. However, whether SMS exerts antihyperuricemic effects is unknown. Methods: Effects of the SMS extract in water (SMS-W) and 30% ethanol (SMS-E) were studied in a rat model of potassium oxonate-induced hyperuricemia. Uric acid concentrations and xanthine oxidase (XO) activities were evaluated in the serum, urine, and hepatic tissue. Using renal histopathology to assess kidney function and uric acid excretion, we investigated serum creatinine and blood urea nitrogen concentrations, as well as protein levels of renal urate transporter 1 (URAT1), glucose transporter 9 (GLUT9), and organic anion transporter 1 (OAT1). The effects of SMS on in vitro XO activity and uric acid uptake were also evaluated. The components of SMS were identified using Ultra Performance Liquid Chromatography (UPLC). Results: SMS-E reduced serum uric acid and creatinine concentrations, and elevated urine uric acid excretion. SMS-E lowered XO activities in both the serum and liver, and downregulated the expression of renal URAT1 and GLUT9 proteins. SMS-E reduced renal inflammation and IL-1b levels in both the serum and kidneys. SMS-E inhibited both in vitro XO activity and urate uptake in URAT1-expressing oocytes. Using UPLC, 25 ginsenosides were identified, all of which were present in higher levels in SMS-E than in SMS-W. Conclusion: SMS-E exhibited antihyperuricemic effects by regulating XO activity and renal urate transporters, providing the first evidence of its applicability in the treatment of hyperuricemia and gout.

  • To develop an effective anti-hangover product, hot-water extracts of 25 medicinal herbs were screened for inhibition or activation of alcohol dehydrogenase(ADH) and acetaldehyde dehydrogenase(ALDH), and 12 herbs were selected for further study. Chosen medicinal herb extracts(CMHEs) were fermented by Lactobacillus delbruechii subspecies lactis for 10 days at $35^{\circ}C$ after saccharification with nuruk(malt inoculated by 5 types of microbs) for 72 hours at $35^{\circ}C$ and both CMHEs and fermented CMHEs(FCMHEs) were explored for anti-hangover effects in vitro. We found significant ADH inhibition by hot-water extracts of Pueraria thunbergiana, Hovenia dulcis Thunb, Lycium chinense, Glycyrrhiza uralensis, Acanthopanax sessiliflorus, Liriope platyphylla, and Ixeris dentata, and significant ALDH activation by extracts of Acanthopanax sessiliflorus, Lycium chinense, Ixeris dentata, and Polypori umbellati of the Polyporaceae. The ADH effects on CMHE and FCMHE were -20.22% and -62.63% of control values, and the ALDH effects 173.20% and 280.17%, respectively. In rats given 20%(v/v) alcohol(15 mL/kg), FCMHEs significantly decreased blood acetaldehyde concentrations on 3 hours after ethanol administration, in a dose-dependent manner(p<0.05). Notably, blood acetaldehyde concentrations were markedly reduced in animals given FCMHEs(400 mg/kg) compared to levels seen in rats receiving CADB(commercial alcohol detoxification beverage). Thus, anti-hangover effects were promoted by fermentation of certain medicinal herb extracts.
