A high-performance liquid chromatography-electrospray ionization-tandem mass spectrometric method was developed to determine simultaneously eight marker constituents of Forsythiae fructus, and subsequently applied it to classify its two botanical origins. The marker compounds of Forsythia suspensa were phillyrin, pinoresinol, phillygenin, lariciresinol and forsythiaside; those of F.viridissima were arctiin, arctigenin and matairesinol. Separation of the eight analytes was achieved on a phenyl-hexyl column (150 ? 2.0 mm i.d., 3 mm) using gradient elution with the mobile phase: (A) 10% acetonitrile in 0.5% acetic acid, (B) 40% aqueous acetonitrile. A few fragment ions specific to the types of lignans, among the product ions generated by collisonally induced dissociation (CID) of molecular ion clusters, such as [M-H]- or [M+OAc]- were used not only for fingerprinting analysis but for the quantification of each epimer by using multiple-reaction monitoring mode. It was shown good linearity (r2 ? 0.9998) over the wide range of all analytes; intra- and inter-day precisions (RSD, %) were within 9.14% and the accuracy ranged from 84.3 to 115.1%. The analytical results of 40 drug samples, combined with multivariate statistical analyses - principal component analysis (PCA) and hierarchical cluster analysis (HCA) - clearly demonstrated the classification of the test samples according to their botanical origins. This method would provide a practical strategy for assessing the authenticity or quality of the herbal drug.
속단(Dipsaci Radix) 중 Asperosaponins 및 Iridoid glycosides의 LC-ESI-MS에 의한 동시분석

Dipsaci Radix (Dipsacaceae) has been used as a tonic, an analgesic, anti-inflammatory and anti-complement agents in traditional herbal medicine for the therapy of low back pain, knee pain, rheumatic arthritis, traumatic hematoma, and bone fractures. A high-performance liquid chromatography-electrospray ionization-mass spectrometric method (HPLC-ESI-MS) was developed for the simultaneous quantitation method of the five compounds from the herbal drug: asperosaponin VI and asperosaponin XII (terpene glycosides), sweroside, loganin and dipsacus A(iridoid glycosides). HPLC separation of the analytes was achieved on a C18 column (150 × 2.0 mm i.d., 5 µm) using the aqueous methanol containing 5 mM ammonium acetate with gradient flow of the mobile phase. Detection of the analytes was performed by positive ion electrospray ionization, and selected ion monitoring was used for data acquisition using m/z corresponding molecular adduct ion, [M+NH-4]^+and [M+H]^+. Calibration graphs showed good linearity (r^2= 0.9997) over the wide range of the analytes; intra- and inter-day precisions (RSD, %) were within 9.1% and the accuracy between 94.0 - 111.0%. Recoveries of the analytes through the assay procedure were in the range of 93.7 - 110.8%. Analytical results of the herbal drugs of Dipsaci Radix (17 samples) show wide distribution of the five marker compounds and clear difference of the species from Phlomidis Radix (4 samples). The developed method would provide a practical guide for the quality control of the herbal drug.
사상인(四象人) 침혈(針穴) 선택의 방법론에 대한 연구(십이정경(十二正經)을 중심으로)

1. Objectives Scarcely referred except for a few phrases of the acupuncture of Dongmugong. He stated every disease could be cured through acupunture. In addition, generally there are a certain point('hyul-穴') of the body that suits according to the constitutions, and just as there are a theory that 'ascend-descend-loosen-tighten(升降緩束)' so as therapy of the symptom has the same. However, he did not indicate the concrete method of the four constitutional acupuncture. He only asked his descendants to study about it. 2. Methods Therefore, author of the thesis tries to describe the theory approach to the seletive method of four constitutional acupunture point based on ${\ulcorner}$Dongyi Suse Bowon(東醫壽世保元)${\lrcorner}$ 3. Results and Conclusions The author of the thesis recommended the methods to apply twelve channels to sasangin's disease and symptoms according to the ascend(升)-descend(降)-loosen(緩)-tighten(束)
