  • Higenamine is a cardiotonic constituent of Aconite root, one of the most important oriental traditional medicine. Since Aconite root contains toxic aconitine alkaloids, variously processed roots have been often used. Much works have been done with the chemical significances concerning with the toxic aconitine alkaloids during the processing periods. However, effects of processing on higenamine have not yet been previously studied. In this paper, the extract pattern and the amounts of higenamine extracted with water from unprocessed and processed Aconite roots were compared. R-(+)-isomer was the only higenamine enantiomer detected although racemic higenamine was reported to be separated from Aconitum spp. Sonication for 1 hour resulted in higher higenamine extraction $(12.3\;{\mu}g/g)$ than boiling water extraction for 3 hours $(6.7\;{\mu}g/g)$ of unprocessed Aconite root. Extraction of not only higenamine but also most of the other components of unprocessed Aconite roots were reduced with boiling in water. Similarly, reduced extraction was observed with extracts of all three processed Aconite roots (Kyung-Po-Aconite root, Dang-Po-Aconite root and Huk-Peon-Aconite root) by either sonicated extraction or boiling water extraction.

  • We have conducted to characterize the physico-chemical change and pharmacological transformation of traditional herbal medicines by means of processing. Processed Gardeniae Fructus was prepared by heating of fruit of Gardenia jasminoides(GF) for $30{\sim}50\;minute$ in the roster designed for herb processing. The contents of drying loss, water extract, diluted ethanol extract, ether extract and geniposide in non-processed GF and processed GF were examined. The contents of drying loss, water extract and geniposide in processed GF showed a decrease as compared with those of non-processed GF, however the contents of dilute ethanol and ether extract showed a increase as compared with those of non-processed GF. The rate of decrease/increase of those index were in proportion to heating time. And, biological activities of methanol extract of non-processed GF and processed GF were investigated. DPPH scavenging effects and inhibitory effect of xanthine oxidate and hemolysis of processed GF exhibited more effective than those of non-processed GF in vitro. Accelerating effect of large intestinal transport and purgative action of non- processed GF were discriminated by processing of GF. Methanol extracts of non-pro- cessed GF and processed GF showed the protective effects against the hepatotoxicity induced by ${\alpha}-naphthylisothiocyanate$ in rats. These results suggested that the transformation of biological activities of GF by means of processing may be due to the physico-chemical change of the constituents in GF by heating.

  • Deep sea water is deeper than 200 m in depth and maintains cool temperatures. It is clean seawater not contaminated by E. coli and other general bacteria. Because deep sea water is a recyclable resource with high industrial value, activities for commercial use are vigorously developing. We investigated safety, quality characteristics, and mineral contents of prototype products using deep sea water as a substitute for a curing agent and compared it with existing commercially processed products. This study examined the potential of deep sea water as an alternative to curing agent solution. As a result, safety and quality characteristics of processed meat products with deep sea water were not different from commercially processed meat products, but mineral contents were higher in processed meat products with deep sea water. Deep sea water could be widely used as purity salt and purity minerals that can replace chemical substances such as chemical salts. A new, active food market using deep sea water will emerge in the near future.

  • Polymeric composites can be subjected to a wide variety of environmemtal conditions in practical use. One of most important conditions to be considered in the stuctural design using such materials is the miisture envirnment. Thus the moisture effect on interlaminar fracture toughness $G_IC$ and $G_IIC$ of CFRP(carbon fiber reinforced plastic) composed of carbon fibers and epoxy resin is studied in this paper. Specimens were first processed in 25, 50, $80^{\circ}C$ flesh water and $25^{\circ}C$ sea water for various periods of time. After that, the water absorption and fracture toughness tests were performed under laboratory atmosphere. As result, the specimen processed in $80^{\circ}C$ flesh water indicates the highest misture absorbing capability, the second in $50^{\circ}C$ flesh water, the third in $25^{\circ}C$ sea water, and the specimen in $25^{\circ}C$ flesh water does the lowest. The interlaminar fracture toughness $G_IC$ increases, approaches to the maximum, and decreases as the immersion time increases. In case of interlaminar $G_IIC$, the value of the specimen processed in $80^{\circ}C$ flesh water turns out to be higher than others. In addition, the scanning electron micrographs(SEM) of fracture surfaces were also examined in order to explain the mechanism of fracture.

  • 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.

  • We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

  • This study was performed to investigate the effect of dietary processed sulfur supplementation on water-holding capacity, color, and lipid profiles of pork according to the level of dietary processed sulfur (0%, CON; 0.3%, S). The pigs were slaughtered at an average final weight of 120 kg, and the longissimus dorsi muscles were collected from the carcasses. As results, pork processed with sulfur had significantly higher moisture and ash contents compared to those of CON but lower crude fat, pH, expressible drip, lower redness and yellowness, and greater lightness. Pork processed with sulfur showed significantly lower total lipid content, triglycerides, and atherosclerosis index but significantly higher high-density lipoprotein cholesterol. Feeding processed sulfur significantly lowered myristic acid, heptadecanoic acid, and stearic acid contents, whereas monounsaturated fatty acids and oleic acids were significantly higher compared to those in the CON. Higher amounts of polyunsaturated fatty acids and n-6 fatty acids were observed in the pork processed with sulfur than that of the CON. Therefore, supplementing pigs with dietary sulfur improved nutrient and meat quality.

  • As pyrite is commonly associated with arsenopyrite, the use of pyrite including arsenopyrite for medicine requires close attention on arsenic toxicity. The toxicity was reduced by traditional processing operations include heating and quenching in vinegar. To verify the scientific effects of this process, pyrite containing many crystals of arsenopyrite was processed at temperatures from 45$0^{\circ}C$ to 85$0^{\circ}C$ and through as many as 5 processing cycles. Arsenopyrite completely disappeared when processed only once at $650^{\circ}C$ while it remained even after 5 processing cycles at 45$0^{\circ}C$. Arsenic was most abundant in medicinal mineral samples processed at 45$0^{\circ}C$ and sharply decreased when processed at $650^{\circ}C$ or 85$0^{\circ}C$ And arsenic extraction test in water was carried out from the processed pyrite medicine on the assumption that pyrite medicines with the lowest As metal content would be most desirable. Arsenic were most abundant in water extracted from medicinal mineral samples processed at 45$0^{\circ}C$ and sharply decreased when processed at $650^{\circ}C$ or 85$0^{\circ}C$. But the extracted As concentrations in water exceeded drinking water standards even when processed at 85$0^{\circ}C$. Increasing temperature promoted elimination of arsenopyrite and reduction of As in medicinal minerals and the extraction solutions. But the effects of processing cycles at the same processing temperature were not clear. Heating temperature is more important than number of processing cycles for the removal of arsenic, and it is necessary to heat pyrite to over $650^{\circ}C$ to remove it.
