Objectives : To investigate the active compounds and therapeutic mechanisms of Atractylodes Lancea(Thunb.) D.C. and Magnolia Officinalis Rehder et Wilson in the treatment of dermatitis accompanied by pruritus, as well as their potential to complement or replace standard drugs. Methods : We conducted the network pharmacological analysis. We selected effective ingredients among the active compounds of research target herbs. Then we explore pathway/terms of the common target proteins among research target herbs, fexofenadine and disease. Results : We selected 9 active compounds are selected from Atractylodes lancea and identified 231 target proteins. Among them, 74 proteins are associated with inflammatory skin diseases that cause pruritus. These proteins are involved in various pathways including, 'Nitric-oxide synthase regulator activity', 'Hydroperoxy icosatetraenoate dehydratase activity, Aromatase activity', 'RNA-directed DNA polymerase activity', 'Arachidonic acid metabolism', 'Peptide hormone processing', 'Chemokine binding' and 'Sterol biosynthetic process'. Additionally, coregenes are involved in 'IL-17 signaling pathway'. Similarly, we selected 2 active compounds from Magnolia officinalis and identified 133 target proteins. Among them, 33 proteins are related to inflammatory skin diseases that cause pruritus. These proteins are primarily involved in 'Vascular associated smooth muscle cell proliferation' and 'Arachidonic acid metabolism'. There is no significant difference between the pathways in which coregenes are involved. Conclusions : It is expected that Atractylodes Lancea will be able to show direct or indirect anti-pruritus and anti-inflammatory effects on skin inflammation accompanied pruritus through suppressing inflammation and protecting skin barrier. Meanwhile, it is expected that Magnolia Officinalis will only be able to show indirect anti-inflammation effects. Therefore, Atractylodes Lancea and fexofenadine are believed to complement each other, whereas Magnolia Officialinalis is expected to provide supplementary support on skin disease.

It was revealed that magnolol and honokiol isolated from the stem bark of Magnolia obovata, had potent antibacterial activity against Bacillus anthracis. A quantitative analytical method of magnolol and honokiol by HPLC has been established, and the amounts of the two components in the dried stem bark of M. obovata were 1, 94% and 0.44%, respectively.

$\beta$-Eudesmol is one of various compounds derived from the bark of Magnolia obovata Thunberg, a medicinal plant. It has been shown that $\beta$-eudesmol also markedly alleviated muscle fasciculation, tremor and convulsion induced by diisopropylfluorophosphate and prolonged the time to death in mice (Chiou et al., 1995). Actually, the extract of magnolia bark has been shown to have depressant actions on the cental nervous system (Watanabe et al., 1973). (omitted)

본 연구는 투과증발법을 이용하여 수용액 중 미량의 목련 향 성분을 농축하는 방법으로, PVDF/PDMS 복합막을 제조하여 지지막의 구조와 활성층의 두께에 따른 분리능의 변화를 살펴보았다. PVDF 지지막은 제막조건인 응고액의 온도가 감소하고 고분자 농도가 증가함에 따라 지지층에서의 표면공극률과 기공의 직경이 감소함을 순수투과실험을 통해서 간접적으로 확인하였고, 복합막에 대한 지지막 구조의 영향을 투과 mechanism식에 적용하여 해석하였다. 또한 PDMS의 두께가 증가됨에 따라 선택도가 증가하는 결과를 통해서, 활성층에서의 물질전달을 Fick's law에 의하여 설명하는데 제한이 있음을 알 수 있었다.

목련 각 부위의 에탄올추출물과 분별물 및 잎 부위에서 단리한 리그난류의 항균활성 검정 결과, 포자발육저해의 성분은 각 부위에 걸쳐서 특히 석유에테르 가용부, 에테르 가용부에 집중되어 있었다. 여기서 효과를 갖는 리그난은 (-)syringaresinol(X III), medioresinol(VI), phillygenin(VIII), kobusinol A(X)이었는데, 이들은 모두 구조적으로는 guaiacyl 및 syringyl의 골격을 갖는 페놀성 수산기의 특징을 보여 주었다. 추출물 및 분별물의 항미생물 활성은 석유에테르 가용부에서 가장 강한 억제효과가 있었다. 공시균에 대한 리그난류의 성장저해 효과는 그다지 현저하지는 않았지만, 이들 리그난류를 함유하는 추출물 및 각 분별물은 리그난과의 상승효과를 보였다.

The bark of Magnolia officinalis has been used in traditional oriental medicine to treat a variety of mental disorders including anxiety and depression. The purpose of this study was to examine the effect of M. officinalis ethanol extract on stress-induced alterations in learning and cognitive function using a passive avoidance test (PAT) and also on anxiety-related behavior using the elevated plus-maze test (EPM) in female rats . The degree of Tyrosine hydroxylase (TH) in the region of the ventral tegmental area (VTA) and the locus coeruleus (LC) was measured using an immunohistochemical method. Corticosterone concentrations in serum were also measured. The ethanol extract from Magnolia officinalis was orally administered to female rats 30 minutes before evaluating their immobilization stress and anxiety-related behavior using an elevated plus-maze test and a passive avoidance test. Time spent in the open arms of the EPM increased in the M. officinalis-treated group compared with that of the saline-treated control group. In the passive avoidance test, the memory and cognitive function improved in the M. officinalis extract-treated group. M. officinalis extracts reduced elevated corticosterone concentrations in serum. Also, stress-induced TH increases were suppressed in the M. officinalis extract-treated group in the LC and the VTA region. These results suggest that M. officinalis might prove to be an effective anxiolytic anti-stress agent.

목련과 수종인 함박꽃나무의 현탁배양세포로부터 생리활성을 갖는 리그난화합물인 (+)-eudesmin을 효율적으로 생산하기 위한 연구로써 플라스크배양 단계에서의 다양한 배양조건들 즉, 배지, 초기 당농도, 교반속도, 초기 접종농도, 그리고 elicitation 효과를 확인하고자 하였다. MS배지를 포함한 4종의 배지에서는 물질의 생산성과 생중량 모두에서 MS배지가 적합한 것으로 나타났다. 130 rpm으로 교반되는 항온배양기에서 $3\%$ sucrose와 0.5 mg/L 2,4-D가 첨가된 MS배지에 0.5 mg (DCW)의 농도로 세포를 접종한 실험구에서 8주 후 플라스크 당 3.71 g (DCW)의 생중량을 얻었으며, 지표물질인 (+)-eudesmin의 함량은 $5\%$ sucrose와 200 mg/L chitosan 처리구에서 $3.2{\mu}g/g$ (DCW)으로 대조구에 비해 1.7배의 증가를 나타내었다. 이와 같은 연구결과는 생물반응기를 이용한 목련과 수종에서의 유용물질 생산 연구에 활용될 수 있을 것으로 사료된다.
