A This study evaluated the antidepressant effects of the herbal mixture CPAE(Cynanchum wilfordii Hemsley, Phlomis umbrosa Turcz, and Angelica gigas Nakai) using several tests, including a test for serotonin 6($5-HT_6$) receptor activity, the forced swimming test(FST), and tests for corticosterone(CORT) and monoamine levels. CPAE showed antagonistic effects on the $5-HT_6$ receptor in a stable $5-HT_6$ receptor-expressing cell line. We subsequently confirmed the antidepressant effects of CPAE in chronic stress model in mice and explored the underlying mechanisms of its action. Specifically, we observed that CPAE treatment significantly reduced immobility time in the FST and effectively restored abnormal levels of CORT in plasma and of monoamines(serotonin, dopamine, and norepinephrine) in hippocampus and prefrontal cortex. These results suggest that CPAE has significant antidepressant effects.

Objectives: The purpose of this study was to investigate the effects of Angelica gigas Nakai extract(AGNE) and Bacillus polyfermenticus KJS-2 (BP2) on atopic dermatitis (AD) induced by 2, 4-dinitrochlorobenzene (DNCB) in mice. Methods: In the experiment, we divided mice into four groups: a control group, a DNCB group, an AGNE group, and an AGNE+BP2 group. Then we examined the changes in scratching frequency, clinical aspects on dorsum skin, immunoglobulin (IgE), cytokines ($TNF-{\alpha}$, IL-6) and expression of COX-2. Resutls: From the experiment, the scratching frequency was significantly dropped in AGNE group and AGNE+BP2 group. Clinical observations of dorsum skin, there were a severe keratotic lesion and drop of dead skin cell in DNCB group, but symptoms of AD were decreased 39.6% in AGNE group and 49.6% in AGNE+BP2 group during 3 weeks. IgE, $TNF-{\alpha}$ and IL-6 were decreased significantly in both AGNE and AGNE+BP2 group. Expression of COX-2 was also decreased significantly in both groups. Conclusions: In conclusion, these data suggest that AGNE can decrease symptoms of AD and BP2 makes AGNE more effective. So AGNE can be useful herbal therapy for AD.

The root of Angelica gigas Nakai (AGN) is used as a traditional herbal medicine in Korea for the treatment of many diseases. However, a major challenge associated with the usage of the active compounds from AGN is their poor water solubility. Therefore, this work aimed to enhance the solubility of active compounds by a chemical (viz. surfactant) and physical (hot melt extrusion) crosslinking method (CPC). Infrared Fourier transform spectroscopy (FT-IR) revealed multiple peaks in extrudate solids representing new functional groups including carboxylic acid, alkynes and benzene derivatives. Differential scanning calorimetry (DSC) analysis of the extrudate showed lower glass transition temperature (Tg) and lower enthalpy (${\Delta}H$) (Tg: $43^{\circ}C$; ${\Delta}H$: <6 (J/g)) compared to the non-extrudate (Tg $68.5^{\circ}C$; ${\Delta}H$: 123.2) formulations. X-ray powder diffraction (XRD) analysis revealed amorphization of crystal materials in extrudate solid. In addition, nanonization, enhanced solubility and higher extraction of phenolic compounds were achieved in the extrudate solid. Among the different extrudates, acetic acid- and Span 80-mediated formulations showed superior extractions. We conclude that the CPC method successfully enhanced the production of amorphous nano dispersions from extrudate solid formulations.

The anti-melanogenic substance was isolated from the root of Angelica gigas Nakai by silica gel column chromatography, preparative HPLC and TLC. As a result of the structure analysis by mass, $^1H$-NMR, and $^{13}C$-NMR spectrometry, the compound was identified as demethylsuberosin. Demethylsuberosin reduced melanin contents of B16F1 melanoma cells in a dose-dependent manner and decreased to about 74% at a concentration $5{\mu}g/ml$. Demethylsuberosin inhibited the expression in microphthalmia associated transcription factor (MITF), tyrosinase, tyrosinase related protein-1 (TRP-1), and tyrosinase related protein-2 (TRP-2) in melanocytes. These results suggest that the whitening activity of demethylsuberosin may be due to the inhibition of the melanin synthesis by down-regulation of MITF, tyrosinase, TRP-1 and TRP-2 expression. Thus, our results provide evidence that demethylsuberosin might be useful as a potential skin-whitening agent.

Objectives : Recently, research has been actively conducted on the efficacy of complexes based on oriental medicine prescriptions for improving immune activity and allergies. In this study, In this study, we aimed to examine the effect of Angelica gigas Nakai and Corni fructus extract (AC), medicinal herbs, among candidate drugs derived through preliminary experiments with various components of oriental medicine prescriptions for allergies, on allergies in RBL-2H3 cells. Methods : We evaluated the effect of the ethanol extract of Ulmus on the allergic inflammatory response in anti-DNP-IgE activated DNP-HSA in RBL-2H3 cells. Cell toxicity was determined by WST-1 assay and the markers of degranulation such as beta-hexosaminidase, histamine, TNF-α and IL-6 production of inflammatory mediators and FcεRI-mediated expression. Results : The results showed that treatment with AC extract (20, 40 and 80㎍/㎖) noncytotoxic levels and significantly inhibited the release of β-hexosaminidase, histamine and the production of TNF-α and IL-6 in RBL-2H3 by the antigen stimulation. Conclusions : These results indicate that AC extract exhibits anti-allergic activity through inhibition of degranulation and inhibition of inflammatory mediators and cytokine release. These findings suggest that AC extract may have potential as a prophylactic and therapeutic agent for the treatment of various allergic diseases.

Background: The Korean name for Angelica gigas Nakai (AGN) is Cham-dang-gui, which grows naturally or is cultivated, and its dried roots are used in traditional herbal medicines. The AGN root exert various pharmacological effects. Despite the various pharmacological effects of the AGN root, there are no reports on its anti-oral microbial effects. The purpose of this study was to reveal the anti-oral microbial effect and the microbial and biochemical changes in oral microorganisms according to the concentration of the ethanol extract of AGN (EAGN) root, and to confirm the possibility of using EAGN as a plant-derived functional substance for controlling oral infectious microorganisms. Methods: Disk diffusion test, growth measurement, biofilm formation assay, and measurements of acid production and buffering capacity were performed to confirm the antibacterial effect of EAGN. Results: EAGN showed anti-oral bacterial effects against Streptococcus mutans and Aggregatibacter actinomycetemcomitans at all concentrations, with S. mutans showing a more susceptible effect at concentrations above 5.0 mg/ml and A. actinomycetemcomitans at 3.75 mg/ml. EAGN treatment significantly reduced A. actinomycetemcomitans growth at all concentrations tested. Biofilm formation was significantly reduced at concentrations above 3.75 mg/ml for S. mutans and 2.5 mg/ml for A. actinomycetemcomitans. Acid production in S. mutans and A. actinomycetemcomitans was significantly increased by treatment with EAGN, and the buffering capacities of S. mutans and A. actinomycetemcomitans increased from an EAGN concentration of 3.75 mg/ml and above. Conclusion: EAGN showed anti-oral bacterial effects against both S. mutans and A. actinomycetemcomitans at concentrations above 3.75 mg/ml, which were thought to be related to the inhibition of their growth and biofilm formation. Therefore, EAGN can be used as a safe functional substance derived from medicinal plants owing to its antibacterial effects against S. mutans and A. actinomycetemcomitans.

고지방 식이 유도 비만 흰쥐에 Monascus purpureus균주로 발효시킨 참당귀 추출물을 식이에 첨가하였을 때 나타나는 체중 및 내장지방의 감소, 혈중 및 조직 내 중성지질 및 과산화지질 수준에 미치는 영향을 평가하였다. FAG섭취로 인해 체중증가 및 내장지방 축적 비율을 효과적으로 낮추었으며, 간 기능 지표로 활용되는 혈중 AST, ALT, LDH 및 ALP 활성 변화는 정상 수치와 비슷한 수준으로 감소되었다. FAG를 섭취함으로서 혈중 중성지질 농도가 정상 수준으로 감소하였으며, 혈중 leptin 호르몬 함량 또한 정상 수치와 비슷한 수준으로 증가하였다. 고지방 식이 섭취로 인한 각 조직 과 혈청 내 과산화지질(TBARS)을 측정한 결과 고지방 식이만 섭취한 C군에 비해 각 실험군에서 유의적으로 감소하였으며, 특히 FAG10군에서 가장 낮은 함량을 나타내었다. Hematoxylin과 eosin 염색 및 Oil red O 염색을 통해 FAG를 섭취함에 따라 간장 내 지질침착도의 감소를 확인였으며, 부고환 주변 지방 조직의 hematoxylin과 eosin 염색으로 지방세포의 크기가 감소되었음을 확인하였다.

당귀로부터 항암활성을 화합물을 silicagel column chromatography를 이용하여 분리 및 정제한 후, $^1H$와 $^{13}C-NMR$ MS, HMQC 및 COSY spectrum(500 MHz $CDCl_3$) 분석을 통하여 분자량 328의 decursin임을 구조 동정하였다. 정제된 decursin을 MCF-7에 24시간 처리한 결과 $20{\mu}g/mL$ 이상에서 농도 의존적으로 암세포주의 성장을 억제하였으며, SW480, HepG2, MCF-7및 293과 같은 인체 암세포주에 대한 decurcin의 $IC_{50}$값은 각각 31.04, 27.24, 20.45 및 $33.60{\mu}g/mL$로 나타나, decursin은 인체 정상세포주인 293세포를 포함한 다른 세포에 비하여 MCF-7에 대하여 가장 높은 성장억제 활성을 보여주었다. MCF-7세포에 decursin을 처리한 결과 대조군에서 균일한 핵의 형태가 관찰된 것에 반해 처리군의 경우는 핵의 응축과 apoptotic body를 보였고, DNA 절편이 관찰되었다. 이 결과는 당귀에서 분리한 decursin은 MCF-7세포에서 apoptosis를 통하여 세포의 성장을 억제하는 것을 암시한다.

이번 연구의 목표는 Bacillus polyfermenticus KJS-2 (B. polyfermenticus KJS-2) 및 Angelica gigas Nakai extracts(AGNE) 추출물의 고지혈증에 대한 효과를 확인 하기 위한 것이다. AGNE에 활성을 나타내는 성분인 decursin과 decursinol angelate (D/DA)의 순도를 확인하였을 때 약 78%로 나타났다. AGNE (0.1-20 mg/ml)를 이용한 HMG-CoA reductase 저해활성은 농도가 증가함에 따라 높은 활성을 나타내었다. Endospore를 형성한 B. polyfermenticus KJS-2 ($1{\times}10^9CFU/ml$)는 약 0.3 mm의 담즙산이 함유된 배지에서 내성이 관찰되었다. Normal control, positive control (atorvastatin), negative control (triton WR-1339) 및 AGNE, B. polyfermenticus KJS-2, AGNE + B. polyfermenticus KJS-2와 Atorvastatin + AGNE + B. polyfermenticus KJS-2투여군의 7개군으로 나누어 실시한 동물실험에서는 몸무게 및 간의 무게는 거의 차이가 없었으나, 신장의 무게는 triton WR-1339만 처리한 군에서 조금 높게 나타났다. B. polyfermenticus KJS-2 및 AGNE를 투여는 HDL-콜레스테롤은 증가시키고, 총콜레스테롤 및 중성지방 함량은 감소시켰다. 또한, 간조직 내에서의 지방 축적 정도를 확인한 결과 B. polyfermenticus KJS-2 및 AGNE투여군에서는 지방 염색의 감소가 나타나 지방의 축적이 감소하였음을 알 수 있다. 따라서, B. polyfermenticus KJS-2 및 AGNE는 고지혈증에 효과가 있음을 시사한다.
