This study investigated the acaricidal and repellent activities of various plant extracts and Cnidium officinale-derived materials against Haemaphysalis longicornis. Among the 24 methanolic plant extracts, C. officinale showed the highest acaricidal activity (93.3%) against H. longicornis. Platycodon grandiflorus, Phytolacca americana, Magnolia denudata, Houttuynia cordata, C. officinale, and Pueraria montana showed significant differences in their repellent activity. Consequently, the activity of solvent-fractionated materials and the derived material of the C. officinale, was investigated and a 90% acaricidal effect was observed three days after hexane fraction treatment, indicating that the repellent response was statistically significant. Butylidenephthalide, which is a C. officinale-derived compound, showed 90% acaricidal activity seven days after treatment. Additionally, all H. longicornis moved to the untreated area in the t-tube olfactometer experiment, confirming the repellent activity of butylidenephthalide. Therefore, the results of this study suggest the use of C. officinale crude extract and butylidenephthalide as potent acaricidals and repellents against H. longicornis, respectively.

Four hundred varieties of plant extracts were screened for inhibitory activity against the NFAT transcription factor which plays an important role in inducing immune response. Among them, the MeOH extract of Cnidium officinale showed potent activity, and the activity-guided separation yielded butylidenephthalide, senkyunolide A and falcarindiol as the active constituents. The $IC_{50}$ value of butylidenephthalide was $1.3{\times}10^{-4}\;M$ and was similar to that of senkyunolide A $(2.1{\times}10^{-4}\;M)$. Interestingly, falcarindiol showed higher activity $(IC_{50},\;2.6{\times}10^{-5}\;M)$ than the two phthalides.

In continuation of our studies on essential oils of Angelica genus(Umbelliferae), We report on the components of essential oils obtained from the root of Angelica tenuissima Nakai(藁子). Oils were obtained from the dried roots by steam distillation and fractionated by column chromatography. Each isolate or fraction was identified by GC, GC-MS and spectral analysis. Essential oils of the root of A. tenuissima(Gaoben) were found to contain $\alpha-pinene,\;camphene,\;\beta-pinene,\;myrcene,\;\alpha-phellandrene,\;\Delta-3-carene,\;p-cymene,\;limonene,\;\gamma-terpinene,\;terpinolene,\;4-vinylguauacol,\;\gamma-elemene$, one aromatic compound, three unidentified sesquiterpene alcohols, butylidenephthalide, senkyunolide and Z-ligustilide which was the most abundant compound comprising 75% of the whole oil. Also butylphthalide and hydroxybutylidenephalide were tentatively identified.

This study was performed to identify the flavor compnenets of Korean Cnidium officinale M.. The extraction of the flavor compounds of Cnidium officinale M. was accomplished by a simultaneous distillation and extraction method using a Likens and Nickerson's extraction apparatus. The concentrated extract was analyzed and identified by gas chromatography and GC-mass spectrometry. The change of the 림팩 contents in each samples was determined in terms of two different storage conditions. The flavor contents of sample at low temperature storage were higher than those at room temperature storage, and increased until storage period of 70 days. The major components of Cnidium officinale M. were terpene compounds including α-pinene, β -selinene, γ-selinene, and phthalides including butylidenephthalide, cnidilide, neocnidilide, senkyunolide A, ligustilide, which are believed to contribute to the characteristic flavor of the Cnidium officinale M.. Especially, great amount of cnidilide and ligustilide was shown in sample of low temperature storage.

Ligusticum Chuanxiong and its components were reviewed in terms of pharmacodynamic mechanisms. Three components of about 40 chemical components in Chuanxiong tetramethylpyrazine, ferulinolol and Butylidenephthalide have mainly been studied for its pharmacodynamic mechanisms which are focused on the increase in blood flow and anti-oxidative stress. The mechanisms for the effects of Chuanxiong on the increase in blood flow can be summarized as four ways, 1) anti-coagulation 2) blocker of ${\beta}1$ adrenergic receptor 3) cellular control of Ca++ level 4) collagen synthesis. Chuanxiong also showed the effectiveness on free radical-induced injury. It seems that its effectiveness is also related to the mechanisms for the increase in blood flow.

Backgrounds: Danggui, one of the major herbs in Korean traditional medicine consists of three species: Angelica gigas of Korea, Angelica sinensis of China, and Angelica acutiloba of Japan. Despite its importance in Korean traditional medicine, recognition of the clinical differences between its three species is insufficient. Objectives: The purpose of the present review is to suggest evidence in using Angelica gigas, Angelica sinensis, and Angelica acutiloba distinctively in clinic, by comparing their pharmacological effects and bioactive compounds. Methods: We searched articles published from 2000 to 2009 in Pubmed, EMbase, and RISS. The search keywords were "Angelica gigas", "Angelica sinensis", "Angelica acutiloba", "dongquei", "toki", "Angelicae Radix", "Archangelica officinalis Hoffm.", "Garden Angelica", "Chinese angelica root", "tangkuei", and "danggui". 861 articles were searched. Among them, we selected 143 articles which met our inclusion criteria. Results: This review summarizes active constituents, experimental studies, clinical studies, pharmacokinetics, side effects and toxicity, drug interaction, and industrial use of Angelica gigas, Angelica sinensis, and Angelica acutiloba. Conclusions: While Angelica sinensis and Angelica acutiloba are relatively similar, Angelica gigas is quite different from the others in main active constituents and genetic form. The main experimental studies of Danggui are cardiovascular studies, central nervous system studies and anti-cancer activity. Even though there were cases in which the three species show similar pharmacological effects, the mechanism was not always shared. Therefore, distinguished use of Angelica gigas, Angelica sinensis and Angelica acutiloba is needed.

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.
