Aconiti Tuber is the root of Aconitum sp (Ranunclaceae) which has been considered as one of the most important medicinal plant having cordiotonic, diuretic and analgesic effect. On the other hand, it has been known that Aconiti Tuber contained toxic agent, aconitine alkaloids so that only processed Aconiti Tubers have been used as herbal drug traditionally. For the safety evaluation of processed Aconiti Tuber, quantitative determination of aconitine and acute, subacute toxicity test were performed on 5 commercial processed Aconiti Tubers. Arapid and precise method using HPLC has been developed for the separation and determination of aconitine. Samples were extracted with hydrochloric acid (pH3) and hot water decoction. In case of d-HCL extracts, the contents of aconitine were from 0.08 mg/g to trace. But in case of hot water decoction extracts, the contents of aconitine were not detected. For the investigation of Aconiti Tuber toxicity in rats, hot water decoction samples and methanol extracts were tested. 1) Acute toxicity test Hot water decoction sample and methanol extracts from Aconiti Tuber did not show any toxic effects in rats by an oral administration. $LD_50values of 2 extracts were above 10.0 g/kg. 2) Subacute toxicity study In the repeated administration study, hot water decoction samples were given orally to Sprague-Dawlay rats for 2 week at daily doses of 5.0 g/kg. The results are as follows; No toxic manifestation, body weight changes and lethality were observed during wxperimental period. There were no significant changes in serum enzyme activities such as GOT, GPT, LDH, ALP between treated and control groups. However CPK values were decreased in the Subuja-treated group. (P<0.01). In addition, no gross and microscopic changes were noted in Aconiti Tuber-treated groups.

This study was designed to investigate the stability for chemical contents and biological activities of Mahwang-tang (MT) depending on the preservation temperature and periods. MT decoction pouches were preserved for 3 months at room temperature (RT, $23{\pm}1^{\circ}C$) and refrigeration ($4^{\circ}C$). To evaluate the stability of MT decoction, pH and sugar content were estimated. High-performance liquid chromatography analysis were performed to quantify the contents of marker compounds in MT. Anti-inflammatory effects of MT were evaluated to suppress the generation of nitric oxide, prostaglandin $E_2$ and cytokines (tumor necrosis $factor-{\alpha}$ and interleukin-6) in the RAW 264.7 cells stimulated with lipopolysaccharide. Total antioxidant capacity of MT was determined by ABTS radical scavenging activity. The pH of storage method and period showed a tendency to decrease gradually with time. There were no changes in sugar content depending on the preservation temperature and periods of MT decoction. Among the major components of MT, cinnamaldehyde was reduced time-dependently for 3 months of storage at RT. The inflammatory effect and antioxidant capacity of MT were reduced time-dependently at both RT and $4^{\circ}C$. Our results suggest that the preservation period of MT decoction is recommended in refrigeration within 3 months or less rather than at RT.

Objectives: This study was performed to compare the differences between decoctions extracted by different extraction method and extraction time. Methods: Decoctions were prepared with pressurized or non-pressurized extraction for 60, 120 and 180min. The yield of extract, total soluble solid content, hydrogen ion concentration(pH) and the content of reference compound in Sipjeondaebo-tang (Siquandabu-tang) were investigated. Results: While yields and the total soluble solid of decoction were higher in pressurized method proportional to extraction time, pH values were lower in pressurized method and showed decreasing values with increasing extraction time. Albilflorin, ferulic acid, nodakenin, coumarin, cinnamaldehyde and glycyrrhizin were contained in decoctions by pressurized extraction method more than non-pressurized method whereas the content of coumarin was higher in decoctions by non-pressurized extraction method. In addition, coumarin was extracted increasingly with extraction time in decoctions by pressurized method, however, nine compounds except cinnamaldehyde showed the tendency of increasing proportional to extraction time. Conclusions: The results show that extraction methods including pressurized or non-pressurized extraction, and extraction time could affect the physicochemical characteristic or composition of Sipjeondaebo-tang(Siquandabu-tang) decoction.

The decocting method of herbal medicines is various with a prescription or herbal medicine's characteristics. But it has common principles by which effective elements can be easily extracted with synergistic actions of herbs and which the therapeutic effect of a medicine is amplified. When decocting a herbal medicine, the volume of water is an important factor. Fire for decocting drugs and decocting time are also important factors. The excessive water and unproper decocting time and temperature can reduce the effect of the decoction. Besides a better decoction can be obtained by squeeze. According to herbal medicine's characteristics and prescription, there are herbs that should be treated after a specific method. For example, decoct first and decoct later. It also affects the therapeutic if a right taking method is not carried out. Methods of taking drugs include both the time and the method. We can confirm these decocting and taking methods in the ancient medical literatures of herbal medicine. This article deals with these things in detail.

Socheongryong-tang (SCRT) was one of the major traditional herbal medicines wildly used in the treatment of respiratory disease. SCRT is being commercially produced in the form of mix extracts powder and soft dry extract by different extract methods in the Korean Herbal Pharmacopeia (KHP). In this study, the contents of marker components and biological activities of the SCRT mix extract powder were compared with those of the SCRT decoction. To analyze the marker components of SCRT, nine marker from eight herbal preparations were chosen. And the method using high performance liquid chromatography (HPLC) with diode-array detector method was established for the simultaneous analysis. Method validation was accomplished by linearity, precision test, and recovery test. The contents of nine marker components in this extract was ascertained by ratio. The biological activities were examined the effect of SCRT on anti-oxidation and pro-inflammation mediated by LPS-stimulation. We confirmed that both of SCRT mix extrct powder and decoction have the similar contents on total polyphenol and flavonoid and inhibited the secretion of nitric oxide (NO), $IL-1{\beta}$, IL-6, tumor necrosis factor $(TNF)-{\alpha}$ and the expression of iNOS, COX-2, $IL-1{\beta}$, IL-6, $TNF-{\alpha}$. These results suggest that SCRT mix extract powder and decoction have a significant correlation.

Purpose: In this study, we investigated anti-thrombotic effects of Gamihyunbooleekyungtang currently used clinical treatment of dysmenorrhea and compared effects by decoction methods. Methods: Gamihyunbooleekyungtang was extracted by pressure extractor (GHYT) and nonpressure extractor(GHYT-1). Inhibitory effect of platelet cohesion, suppression effect of GPIIb/IIIa activity, inhibitory effect of $TXB_2$ and $PEG_2$ biosynthesis, and oxidative damage suppression effect were tested in vitro. Also suppression of pulmonary embolism was studied in vivo. Results: In this study, both GHYT and GHYT-1 extract showed a safety in cytotoxicity of hFCs. Both showed dose-dependent inhibitory effect on platelet coagulation. GHYT-1 extract is usually higher than GHYT, especially for $E_{max}$. GHYT and GHYT-1 extract showed dose-dependent inhibitory effect on GPIIb/IIIa activities. GHYT extract suppressed significantly $TXB_2$ biosynthesis at 1000, $500{\mu}g/m{\ell}$ and also suppressed significantly $PEG_2$ biosynthesis at $1000{\mu}g/m{\ell}$ as compared with the control group. GHYT-1 suppressed significantly $TXB_2$ biosynthesis at $1000{\mu}g/m{\ell}$ as compared with the control group. Also it suppressed pulmonary embolism triggered by collagen and epinephrine by respectively 50%, 75% as compared with the control group. Both GHYT and GHYT-1 extract showed dose-dependent decrease of oxidative damages caused by DPPH, whereas dose-dependent increase of superoxide dismutase like activity was observed. Conclusion: These results suggest that Gamihyunbooleekyungtang can be used for treating dysmenorrhea caused by thrombosis. Nonpressure decoction method is a little more effective, but more detailed studies would be needed.
