The essential oil fraction was obtained from the underground parts o of Ligusticum chuanxiong (Umbelliferae) by steam distillation, and its main components, Z-ligustilide and butylidene phthalide, were isolated by column chromatography. Its essential oil fraction and the isolated main components were examined for effects on their anti-inflammatory properties in RAW 264.7 macrophage cells to develop a new natural anti-inflammatory drug. The results showed that the L. chuanxiong essential oil fraction and its main components, Z-ligustilide and butylidene phthalide, inhibited the production of nitric oxide significantly in lipopolysaccharide (LPS)-treated RAW 264.7 cells. LPS-induced interleukin-$1{\beta}$ (IL-$1{\beta}$), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-$\alpha$) production was also decreased in a dose-dependent manner. In addition, western blot analysis revealed that the L. chuanxiong essential oil fraction and also its main components, Z-ligustilide, and butylidene phthalide reduced the expression levels of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS).

The anti-melanogenic effects of the extract of Angelica tenuissima (AT) root and the extract of AT root fermented by Aspergillus oryzae (FAT) were investigated. These effects were determined by measuring the inhibitory activity of AT and FAT on melanin production in B16F10 melanocytes and with in vitro tyrosinase activity assays. The AT extract inhibited melanin production at concentrations above $250{\mu}g/ml$, and this inhibitory effect was significantly enhanced by the fermentation process with A. oryzae. HPLC analysis resulted in the isolation of two active compounds from both the AT and FAT extracts. Their chemical structures were identified as decursin and Z-ligustilide through comparison with previously reported NMR data. The decursin and Z-ligustilide contents were increased in the FAT extract and could be responsible for its enhanced inhibitory effects on melanin production and tyrosinase activity compared with that of the AT extract.

Angelicae tenuissimae Radix의 정유성분에 대한 구조규명과 채취장소에 따른 정유성분의 정량실험 결과 및 Ligustici rhizoma와의 정성 정량적 차이점에 관한 실험을 하여 다음과 같은 결론을 얻었다. Ligustici rhizoma와 Angelicae tenuissimae Radix 산지별 네가지 시료의 용출함량을 비교한 결과 경북 석포에서 채집한 시료가 11.32%로 가장 높은 값을 나타내었고, 중국산 Ligustici rhizoma가 3.49%로 가장 낮은 용출함량을 나타냈다. GC/MS로 구조를 분석한 결과 Angelicae tenuissimae Radix의 정유성 분은 ${\alpha}-pinene,\;{\alpha}-phellendrene,\;{\delta}-3-carene,\;{\gamma}-terpinene$, 4-vinylguaiacol, ${\alpha}-farnesene,\;(t)-{\beta}-farnessene,\;{\gamma}-elemene$, sesquiterpene alcohol, butylphthalide, senkyunolide, butylidenephthalide, z-butylidenedihydrophthalide (z-ligustilide) 등을 확인할 수 있었는데, Ligustici rhizoma 정유성분에서는 Angelicae tenuissimae Radix와 다르게 senkyunolide가 38.7%로 주성분이었으며, butylphthalide(17%), cnidilide(8.8%), z-ligustilide(8.8%) 등을 함유하였다. 따라서 Ligustici rhizoma와 Angelicae tenuissimae Radix의 주성분이 서로 상이하며, 그 조성비도 큰 차이가 있음을 확인할 수 있었다. 본 연구 결과로부터 고본의 주성분은 ligustilide (한국산 고본)과 senkyunolide (중국산)로서 앞으로 임상실험을 통하여 이들 성분의 정확한 약리효과를 규정함으로써 고본(藁本)을 규격화 하여야 할 것으로 생각된다.

The present study aimed to assess the antifungal properties of the essential oil fraction from Ligusticum chuanxiong (Umbelliferae) and its components against five clinically important Aspergillus species. The essential oil fraction was extracted from the underground parts of the plant by steam distillation, and its main components, namely, Z-ligustilide, butylidene phthalide, and p-cresol were isolated by column chromatography. The antifungal activities of the essential oils were evaluated by the broth dilution method. Both the total essential oil fraction of L. chuanxiong and its components showed significant anti-Aspergillus activity against all five tested strains with MICs between 62.5 and 250 ${\mu}g$/ml, respectively. In a checkerboard microtiter assay, the combination of antibiotics, itraconazole with the essential oil fraction of L. chuanxiong or its main components exhibited synergistic or additive, and in some cases indifferent, effects against the tested Aspergillus species, resulting in FICIs (fractional inhibiting concentration indices) ranging from 0.12 to 2, while the combination of antibiotics, amphothericin B with L. chuanxiong essential oils mostly showed antagonistic effects.

Major separation for the active ingredients and characterization of chemical properties in conjunction with screening test on animal were performed in order to analyze and standardize Ligustici Rhizoma or Angelicae Tenuissimae Radix as an important oriental herbal medicine for antiphlogistic or an important oriental herbal medicine for antiphlogistic or an anodyne. Furthermore the structure, composition and contents of ingredients for essential oil in Angelicae Tenuissimae Radix(Suckpo, Korea) were determined by means of Ge/MS followed by screening test on Z-ligustilide(82%) known as major ingredient as well as butylidenephthalide collected by HPLC with normal phase semiprep-column. The total active ingredient in Ligustici Rhizoma from China or Angelicae Tenuissimae harvested at Choonyang(Kyungnam, Korea), Jungsun(Kangwon, Korea), Suckpo(Kyungnam Korea), Youngchun(Kyungnam, Korea) have been determined showing higher abundant for three times on the product in Korea compared to that in China. In addition, the major component in Ahgelicae Tebyussunae Radux extract was found to be Z-ligustilide(70-80%) which is very different from that in Ligustici Rhizoma senkyunolide(39%) as major species. For screening test of Ligustici Rhizoma or Angelicae Tenuissimae Radix extracts toward the target animal, the efficiency has been shown the similarity on both extracts. Taking into account the level of ingredient, the total efficiency may be three times higher on Angelicae Tenuissimae Radix in Korea compared to Ligustici Rhizoma in China. As a result of present study, it is preferable to distinguish between Ligustici Rhizoma and Angelicae Tenuissimae Radix for better usage of oriental herbal medicine because of very different composition and abundant in spite of their similar screening effect.
