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.

고령화 사회에서 비만을 예방하는 것에 대한 관심이 높아지는 추세에 따라, 남성과 여성 모두 비만 관리에 상당한 비용과 노력을 지불하고 있는 실정이다. 본 연구에서는 항비만 효과를 증명하기 위해서는 3T3-L1 지방전구세포를 이용한 연구가 필수적으로 수행되기 때문에, 3T3-L1 지방전구세포에서 항비만 효과를 지닌 천연물에 조사하였다. 70% 에탄올을 이용한 사상자(Torilis Japonica Decandolle) 추출물이 3T3-L1 지방전구세포에서 성숙한 지방세포로의 분화에 미치는 효과를 Oil red O assay, western blot을 통해 확인하였다. 대조군에 비해 사상자 추출물의 $100{\mu}g/ml$ 농도에서 지방세포 분화와 세포 내 triglyceride (TG) 수준을 효과적으로 억제하였다. TG 함량 감소 메커니즘을 규명하기 위해, peroxisome-proliferatorsactivated-receptor-${\gamma}$ ($PPAR{\gamma}$) 및 CCAAT enhancer-binding-proteins-${\alpha}$ ($C/EBP{\alpha}$), acetyl-CoA carboxylase (ACC)의 인산화 등 항비만 관련 단백질의 표현 수준을 확인하였다. 그 결과, 사상자 추출물은 $PPAR{\gamma}$, $C/EBP{\alpha}$, ACC 인산화 단백질의 발현 정도를 현저하게 감소시켰다. 종합하자면, 사상자 추출물이 비만 예방에 가장 효과적인 후보임을 명백하게 보여준다. 더 나아가서, 천연물인 사상자의 항비만 효과에 핵심적인 역할을 수행하는 활성 화합물을 탐색 및 분리하기 위한 추가 연구가 필요하다고 사료된다.

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.

Objectives: This study was conducted to confirm the anticancer effect of Torilis Japonica (TJ) on cervical cancer and to determine whether the effect was apoptosis. Methods: In this study, the effect of TJ extract on toxicity, mitochondrial morphology, nuclear morphological changes, Extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) pathway were investigated in HeLa cell, human cervical cancer cell. Results: The cytotoxicity, ratio of cells with nuclear changes to the total number of cells, and P38 phosphorylation increased in a concentration-dependent manner after administration of TJ extract. The length of mitochondria and ERK phosphorylation in HeLa cells decreased in a concentration-dependent manner after administration of TJ extract. Conclusions: TJ extract has an anticancer effect on cervical cancer cells, which is presumed to be due to apoptosis, and showed potential as a future cervical cancer treatment.

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.

To confirm the antimicobial mechanism of Torilis japonica, antimicrobial profile was observed on various spore conditions by combining 0.1% (3 mM) torilin with antimicrobial activity and 0.27% water fraction with germinants. A 75% ethanol extract of T. japonica fruit reduced Bacillus subtilis ATCC 6633 spore counts by 3 log cycles and reduced the vegetative cells to undetectable level (by about 6 log cycles) (both in terms of CFU/mL). Further fractionating the ethanol extract into n-hexane and water fractions revealed that the former reduced the spore count by 1 log cycle whereas the latter had no effect. The antimicrobial active compound was isolated and purified from the hexane layer, and identified as torilin ($C_{22}H_{32}O_5$). The water fraction of the ethanol layer did not show antimicrobial activity, whereas the antimicrobial effect of 0.1% (3 mM) torilin was significantly enhanced in the presence of the water fraction (0.27%). This result can be explained by synergistic effects of the water fraction containing considerable amounts of germinants such as L-alanine and K+ ions that triggered germination.

Torilin was isolated from haxane fraction of Torilis Fructus extract. Torilin produced inhibition of the acetic acid-induced and phenylquinone-induced writhing syndrome at the oral doses of 30 and 90 mg/kg in mice. It also increased the pain threshold at the oral doses of 30, 90 and 270 mg/kg in the tail pressure method and the Randall-Selitto method. However, it did not show a hypothermic action at the oral doses of 30 and 90 mg/kg in mice. The compound exhibited strong anticarrageenan activity at the oral doses of 90 and 270 mg/kg in rats, and had inhibitory effect on the vascular permeability at the oral doses of 30 and 90 mg/kg in mice. It also showed potent inhibition of leucocyte emigration in CMC-pouch at the doses of 3 and 9 mg/rat, sc. The acute toxicity of torilin was very weak: the $LD_{50}$ values were more than 5000 mg/kg, po and 2000 mg/kg, ip in mice. From the above mentioned results, it was suggested that torilin had potent analgesic and anti-inflammatory activities.

Bacterial endospores, especially those of Bacillus and Clostridium genera, are the target of sterilization in various foods. We used Bacillus subtilis ATCC 6633 spores to screen novel antimicrobial substances against spores from medicinal plants. We collected 79 types of plant samples, comprising 42 types of herbs and spices and 37 types of medicinal plants used in traditional medicine in Korea and China. At a concentration of 1%(w/v), only 14 of the ethanol extracts exhibited antimicrobial activity against B. subtilis spores of at least 90%. Crude extracts of Torilis japonica, Gardenia jasminoides, Plantago asiatica, Fritllaria, and Arctium lappa showed particularly high sporicidal activities, reducing the spore count by about 99%. Consideration of several factors, including antimicrobial activity, extraction yields, and costs of raw materials, resulted in the selection of T. japonica, G. jasminoides, A. lappa, and Coriandrum sativum for the final screening of novel antimicrobial substances. Verification tests repeated 10 times over a 4-month period showed that the ethanol extract of T. japonica fruit reduced aerobic plate counts of B. subtilis spores the most, from $10^7$ to $10^4\;CFU/mL$ (99.9%) and with a standard deviation of 0.21%, indicating that this fruit is the most suitable for developing a novel antimicrobial substance for inactivating B. subtilis spores.
