Psoralen is used in the treatment of vitiligo and angelicin(isopsoralen) is a photosensitizing agent. A reversed-phase high performance chromatographic method was developed to determine the contents of psoralen and angelicin from Psoraleae Semen and processed Psoraleae Semen. The contents of psoralen and angelicin from Psoraleae Semen showed 0.39% and 0.34% respectively. Processing Psoraleae Semen showed that increased the contents of psoralen (0.52%) and angelicin (0.50%).

A reversed phase HPLC method was developed to determine the major components of Psoralea corylifolia, psoralen, isopsoralen, bakuchiol, and corylin. Quantitative analysis of the above compounds was performed by C-18 column using a gradient solvent system of acetonitrile and water with UV detection at 310 nm. The comparison of contents of psoralen, isopsoralen, bakuchiol, and corylin in psoraleae semen and the processed psoraleae semen was also investigated. In result, processed psoraleae semen showed more amounts of psoralen, isopsoralen, and corylin with 1.6, 4.3, and 1.3 mg/g, respectively, except bakuchiol (66.98 mg/g) while psoraleae semen showed 0.53, 1.56, 1.0, and 76.3 mg/g of psoralen, isopsoralen, corylin, and bakuchiol, respectively.

Ubiquitin-proteasome proteolytic system plays an important role in selective protein degradation and regulates cellular events including apoptosis. Cancer cells have been shown to be more sensitive to the proapoptotic effects of proteasome inhibition than normal cells. Thus, proteasome inhibitor can be potential anticancer agent. Since the MeOH extracts of psoraleae semen and processed psoraleae semen showed potent proteasome inhibition activity, the fractions of the extracts were evaluated on the activity to screen the proteasome inhibitors. The $CHCl_3$ fr. of the processed psoraleae semen showed the most potent activity, of which chemical investigation led to two coumarins, psoralen and isopsoralen. Their structures were determined by spectroscopic methods such as $^1H-NMR$ and EIMS spectra.

This study investigated bacterial growth-inhibitory effect of 69 therapeutic herbal plants extracts on 9 bacterial strains using a disc diffusion assay. Especially, the antimicrobial activity of Psoraleae semen, which showed different activity on pathogenic Gram-positive and Gram-negative bacteria, was evaluated by MIC (minimal inhibition concentration) and biofilm formation assay. The effect of Psoraleae semen extract on bacterial cell membranes was examined by measurement of protein leakage (optical density at 280 nm) and scanning electron microscope (SEM). No clear zone was formed on discs containing Gram-negative bacteria, but Gram-positive bacteria exhibited clear zones. The MICs of Psoraleae semen extract were $8{\mu}g/mL$ for Streptococcus mutans, and $16{\mu}g/mL$ for Enterococci and Staphylococcus aureus. In addition, biofilm formation was inhibited at concentration $8-16{\mu}g/mL$. Protein leakage values and SEM images revealed that cell membranes of Gram-positive bacteria were impaired following exposure to the extract. Further, the extract inhibited the growth of Listeria monocytogenes in sausages. These results indicate that Psoraleae semen extract could be utilized as a natural antimicrobial agent against Gram-positive bacteria.

본 연구에서는 신생혈관형성 제어에 바탕을 둔 비만세포제어 정도를 확인하기 위하여 4가지 지역 천연산물인 전호(Anthrisci radix), 파고지 (Psoraleae semen), 희첨 (Siegesbeckiae herba) 및 산수유 (Corni fructus)를 이용한 지방 축적물 변화 및 기전을 확인하기 위해 3T3-L1 adipocyte를 이용한 Oil Red O 염색 및 western blot을 실시하였다. 그 결과 전호, 파고지, 희첨, 산수유의 세포 독성 이내의 농도 증가에 따라 지방 축적물이 감소됨을 보였다. 또한 western blot을 위해 lipogenesis와 관련된 SREBP-1 및 adipogenesis와 관련된 $PPAR\gamma$와 C/$EBP\alpha$의 신호전달 정도를 확인한 결과 4가지 지역 천연산물의 농도 증가에 따라 단백질의 발현양이 감소됨을 확인하였다. 이는 4가지 지역 천연산물 추출물이 지방분화와 관련된 신호분자를 차단함으로써 지방형성이 억제되었음을 보였다. 따라서 4가지 지역 천연산물인 전호, 파고지, 희첨 및 산수유는 신생혈관형성 억제에 따른 항비만제제로서의 이용 가능함을 시사하였다.

The extract was studied using diphenyl-picryl-hydrazyl (DPPH) for DPPH method. DPPH radical scavenging activity was measured after. .10, 20 and 30 minutes. The extract was tested by 1, 5, 10, 50, 100, 500 and $1000{\mu}g/ml$ concentrations. The results showed that the extract scavenged DPPH radical with time-dependent manner. Also, the extract showed dose-dependent DPPH radical scavenging activity. The extract of Cuscutae Semen, Psoraleae Fructus, Cnidii Fructus and Epimedii Herba scavenged DPPH radical with the IC50 being 2.7, 3.2, 2.9 and 1.1 mg/ml, respectively. In conclusion, the extract of Epimedii Herba, Cuscutae Semen, Cnidii Fructus and Psoraleae Fructus have antioxidant activity for the treatment of male sterility.

It was claimed that the herbal medicine with the function of strengthening the body resistance exerts to enhance the immunity. And the medicine with the effect of eliminating the pathogenic factor is stated to inhibit the immune response. To evaluate the the effects of the herbal medicine on the immune response, the mice were administrated with the herbal medicine for 2 weeks. And the responses were analyzed. As the result, water extract of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Semen Coicis, Herba Ecliptae, Spica Prunellae, and Radix Sophorae increased the ROI production, while Radix Tripterygia inhibited it. Phagocytic activity was increased after administration of Radix Astragal, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Radix Sophorae. NK cell activity was also significantly inhibited by Radix Tripterygia. Administration of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Semen Coicis enhanced the antibodies(hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen, while Radix Sophorae and Radix Tripterygia decreased it. Radix Sophorae and Radix Tripterygia also decreased the allogenic immune response and mixed-lymphocyte reaction. And all the experimental herbs decreased contact hypersensitivity against dinitroflurobenzene. These results show Radix Astragali, Fructus Psoraleae, Spica Prunellae, Cortex Acanthopanacis, Semen Coicis and Herba Ecliptae enhanced innate immunity, humoral and cellular immune responses. However Radix Sophorae and Radix Tripterygia exert imunosuppressive action. Also these results indicate that the medicine with the action of the strengthening the body resistance enhances the immunity. And the the some of drugs belonging to the eliminating the pathogenic factor also increase the immune responses.

Objectives : The increase of osteoclasts could cause osteoporosis and bone-related diseases. Also, the inhibition of osteoclast differentiation is important in treating bone-related diseases. Traditionally, Psoraleae Semen has been used for geriatric diseases, aging and musculoskeletal diseases. The purpose of this study is to investigate the effect of Psoraleae Semen ethanol extract (PS) on osteoclast differentiation and its function. Methods : To confirm the effect of PS on osteoclastogenesis and bone resorption activity, various levels of concentrations of PS (5, 10, 20 and 40 ㎍/ml) were tested on RAW 264.7 cells cultured with RANKL. We measured tartarate-resistant acid phosphatase (TRAP)-positive cells, TRAP activity, pit formation and F-actin ring formation. The expressions of nuclear factor of activated T-cells (NFATc1) and c-Fos were confirmed through western blot and reverse transcription- polymerase chain reaction (RT-PCR). Also, the expression of bone resorption and fusion-related genes in osteoclast was confirmed by RT-PCR. Results : PS decreased the number of TRAP-positive cells and the TRAP activity. In addition, PS significantly inhibited the formation of pit and F-actin ring. Furthermore, PS decreased the expression of osteoclast related genes. Conclusions : PS inhibits osteoclast differentiation and bone resorption ability through inhibition of the expression of osteoclast-related genes. This indicates that PS may be a potential therapeutic agent to osteoporosis by suppressing osteoclastogenesis.
