Osteoporosis is a disease that causes the weakening of bone by increasing porosity, which often results in fractures. Osteoporosis treatment measures include the use of Bisphosphonates and estrogen. However, these treatments cannot be used in the long term as these treatments have adverse side effects. Therefore, there is a need to identify better and safer treatment options. For this, 63 plant extracts were screened and among them, six extracts showed high anti-osteoclastic activity with low cytotoxicity. Of these six extracts, three extracts, Cudrania tricuspidata (P371), Ulmus davidiana var. japonica (P401), and Torilis japonica (P411), showed more than 50 percent osteoclast inhibition. While the remaining, Stewartia pseudocamellia extracts I and II (P370, P397) and Cuscuta chinensis (P418), showed moderate or between 40-50 percent osteoclast inhibition. Among all the extracts, Torilis japonica (P411) showed the highest inhibitory action against osteoclast development. Torilis japonica (P411) primary components include Kaempferol, Quercetin, and Luteolin, all proven to inhibit osteoclastogenesis. Stewartia pseudocamellia extracts I and II (P370 and P397) showed moderate or 44% osteoclast inhibition. Stewartia pseudocamellia extract II (P397) enhanced the growth of RAW 264.7 cells by 19%. Torilis japonica (P411) and Stewartia pseudocamellia extract II (P397) suppressed the expression of osteoclast-specific genes in RANKL-induced osteoclastogenesis in RAW 246.7 cells. Torilis japonica (P411) extracts even increased osteoblast-specific RUNX2 gene expression. This results provide that six extracts could be used as a potential treatment option for osteoporosis disease with the extracts of Torilis japonica (P411) and Stewartia pseudocamellia (P397) as an ideal candidates. However, the combination of the extract with higher osteoclastic inhibition and less toxic effects with further analysis should be recommended.

Owing to increased interest in preventing obesity in an aging society, both men and women spend considerable amount of cost on obesity managements. In this study, we investigated the natural substances on anti-obesity activities in 3T3-L1 pre-adipocytes. Also, to improve anti-obesityeffects, research using 3T3-L1 pre-adipocytes cells is crucial. The anti-obesity effect of 70% ethanol extract from Torilis Japonica Decandolle on the differentiation of 3T3-L1 pre-adipocytes to adipocytes was investigated by suppressing adipocyte differentiation and lipid accumulation with Oil Red O assay, and western blot analysis. Compared to the control, 70% ethanol extract of Torilis Japonica Decandolle was significantly inhibited adipocyte differentiation and intracellular triglyceride (TG) level at a concentration of $100{\mu}g/ml$. To determine the mechanism of reduction in TG content, we determined the level of protein expression of obesity-related proteins, such as peroxisome-proliferatorsactivated-receptor-${\gamma}$ ($PPAR{\gamma}$) and CCAAT enhancer-binding-proteins-${\alpha}$ ($C/EBP{\alpha}$), and Acetyl-CoA carboxylase (ACC) phosphorylation. As a results, 70% ethanol extract of Torilis Japonica Decandolle significantly decreased protein expression of $PPAR{\gamma}$, $C/EBP{\alpha}$ and ACC phosphorylation. These results indicate that 70% ethanol extract of Torilis Japonica Decandolle is the most effective candidate for preventing obesity. However further studies will be needed to identify the active compounds that confer the anti-obesity activity of Torilis Japonica Decandolle.

The methanol extract of Torilis Fructus showed potent anti-edematous effect in carrageenan-induced paw edema in rats. Systematic fractionation of the extract with hexane, chloroform, ethyl acetate and butanol resulted in potent anti-edematous action only in hexane fraction at an oral dose of 237 mg/kg which is corresponding to 4.8 g of raw Fructus. This hexane fraction showed inhibitory effects at 77 mg/kg p.o on vascular permeability in mice, at 8mg/pouch on leucocyte emigration in rats, and at 120 mg/kg p.o. on adjuvant arthritis model in rats. These results demonstrate that hexane fraction of the extract possesses potent anti-inflammatory effect which may support its traditional uses.

Torilin is a major sesquiterpene of Torilis japonica (Umbelliferae) fruits and known to be a melanogenesis inhibitor. Extraction conditions are important factor for the efficient preparation to save cost and time in economic aspects. For this reason, this study was conducted to optimize the extraction condition for maximal yield of torilin. For optimization, extraction factors such as extraction solvent, extraction temperature and sample/solvent ratio were tested and optimized for maximum yield of torilin using response surface methodology with Box-Behnken design (BBD). The optimal condition was obtained as a EtOAc concentration in MeOH of 31.8%, an extraction temperature at $30.3^{\circ}C$ and a sample/solvent ratio, 1000 mg/2 ml. The torilin yield under optimal conditions was found to be 9.9 mg/g dried samples, which were well-matched with the predicted value of 10.4 mg/g dried samples. These results will provide useful information about optimized extraction conditions for the development of torilin as cosmetic therapeutics to reduce skin hyperpigmentation.

Objectives : Cnidii Fructus is prescribed as the fruit of Cnidium monnieri (L.) Cusson or Torilis japonica (Houtt.) DC. in Korea pharmacopoeia. Although there are differences in the composition of useful components, two species have been used without distinction. In order to discriminate them, DNA sequencing and taste pattern analysis were used in this study. Methods : Primers ITS 1 and ITS 4 were used to amplify the intergenic transcribed spacer(ITS) region of nuclear ribosomal DNA from seven T. japonica and six C. monnieri samples. Taste pattern of samples were measured by using taste-sensing system SA402B equipped with five foodstuff sensors(CT0, C00, AAE, CA0, and AE1). The five initial taste(sourness, bitterness, astringency, umami, and saltiness) and three aftertaste(aftertaste of bitterness, astringency, and umami) of two species were compared. Results : According to the results of ITS region sequence analysis, two species showed 94 base pairs differences. The similarity of two sequences was 85%. From the taste pattern analysis, sourness, bitterness, aftertaste of bitterness(aftertaste-B), and umami showed a different pattern. Especially, bitterness and aftertaste-B of C. monnieri were significantly higher than T. japonica. In addition, two species were shown to have two markedly different clustering by these two flavors. Conclusion : T. japonica and C. monnieri were effectively discriminated using DNA sequencing and taste pattern analysis. These methods can be used to identify the origin of traditional medicine in order to maintain therapeutic efficacy.

The spread of antibiotic-resistant strains of Staphylococcus aureus, a gram-positive opportunistic pathogen, has increased due to the frequent use of antibiotics. Inhibition of the quorum-sensing systems of biofilm-producing strains using plant extracts represents an efficient approach for controlling infections. Torilis japonica is a medicinal herb showing various bioactivities; however, no studies have reported the anti-biofilm effects of T. japonica extracts against drug-resistant S. aureus. In this study, we evaluated the inhibitory effects of T. japonica ethanol extract (TJE) on biofilm production in methicillin-sensitive S. aureus (MSSA) KCTC 1927, methicillin-resistant S. aureus (MRSA) KCCM 40510, and MRSA KCCM 40511. Biofilm assays showed that TJE could inhibit biofilm formation in all strains. Furthermore, the hemolysis of sheep blood was found to be reduced when the strains were treated with TJE. The mRNA expression of agrA, sarA, icaA, hla, and RNAIII was evaluated using reverse transcription-polymerase chain reaction to determine the effect of TJE on the regulation of genes encoding quorum sensing-related virulence factors in MSSA and MRSA. The expression of hla reduced in a concentration-dependent manner upon treatment with TJE. Moreover, the expression levels of other genes were significantly reduced compared to those in the control group. In conclusion, TJE can suppress biofilm formation and virulence factor-related gene expression in MSSA and MRSA strains. The extract may therefore be used to develop treatments for infections caused by antibiotic-resistant S. aureus.
