  • The in vitro anticoagulant and fibrinolytic activities of crude extract from insects which have been used as traditional medicines. The extracts of Formica, Huechys and Eupolyph-aga/Steleophaga prolonged activated partial thromboplastin time and thrombin time compared to the value of the control. The fibrinolytic activity of insect extracts was also tested by fibrin plate method. We found that the extracts of Cicadae Periostracum, Eupolyphaga/Steleophdga, Mantidis $O{\ddot{o}}otheca$ and Huechys directly could hydrolyze the fibrin clot without the activation of plasminogen by plasminogen activators.

  • To investigate the effect of ginseng extracts on the changes of flllidity and lysis of liposome reverse phase evaporation vesicle (REV) was employed as model membrane and methylene blue was used as photosensitizer. Fluoresence polarization (P vaule) that represented fluidity of liposome was increased by photooxidation. All of the ginseng saponin inhibited the increasing rate of P value; the order of effect was ginseng water extract>biol saponin>triol saponin>crude saponin. In trapped G-6-P% measurement for lysis of liposome, ginseng water extract and crude saponin promoted the lysis of liposome. Therefore, we thought that ginseng extracts acted as both antioxidant and detergent.

  • This study was attempted to screen the cytotoxic activity of petroleum ether ex- tract from panax ginseng root against human colon cancer cells. Two extracts of panax ginseng root, crude and partially purified, were used for this experiment. The crude extract was prepared by extraction with petroleum ether using Soxhlet aparatus for 12 to 15 hours from panax ginseng and the extract was partially purified by silicic acid column with mixture of petroleum ether: ethyl ether (70 : 30, v/v). Three species of human colon cancer cells, HRT-18, HCT-48 and HT-29, were maintained in DMEM (Dulbecco's modified Eagle medium), and the cells were cultured in DMEM containing serial concentration of the crude or partially purified fraction to observe the cytotoxic activity of the both extracts. The effects of incubation time and concentration of the both extracts in culture medium against the growth of the each cancer cell were determined. The results obtained are summarized as follows: 1. The doubling times of the HRT-18, HCT-48 and HT-29 cells were about 20, 24 and 22 hours, respectively. 2, The inhibitory effects of the crude extract on the growth of cancer cells were increased according to the rise of concentration of the extract and incubation time. 3. The inhibitory effect of partially purified fraction on the growth of HRT-18 cell was about 4 times stronger than that of the crude extract under same experimental condition. 4 The inhibitory effects of the crude and purified fraction on the growth of each cancer cell were shown difference by the kind of the cancer cell. In view of the above results, it could be said that the petroleum ether extract of panax ginseng root inhibited the division of the human colon cancer cell, in vitro.

  • Ginseng saponins have been known as main active principles and are quantified as the index components of ginseng and its products for quality control. However ginseng saponins are easily hydrolyzed in acidic solutions of crude drug preparations. Due to the hydrolysis of saponins in acidic condition, it is generally difficult to determine ginseng saponins In crude drug preparations. Ginseng saponins, prosapogenins and sapogenins of crude drug extracts were quantified by HPLC. Ginseng saponins were quantified by HPLC on $Lichrosorb-NH_2$ column with acetonitrile/water/1-butanol(80:20:10, v/v). Ginseng $prosapogenin-Rg_2$ and $-Rg_2$ were extracted with ethyl acetate from $50\%$ acetic acid hydrolyzates of saponin fractions and quantified by HPLC on $Lichrosorb-NH_2$ column with acetonitrile/water(90:10, v/v). Ginseng sapogenins, panafadiol and panaxatriol, were extracted with diethyl ether from $7\%-sulfuric$ acid hydrolyzates of saponin fractions and quantified by HPLC on ${\mu}-Bondapak\;C_{18}$ column with acetonitrile/methano1/chloroform(83:10:7, v/v). These methods of analyses of sapogenins and prosapogenins were more useful for quality control than those of ginseng saponins in some of crude drug preparations.

  • Some crude drugs in ancient literatures have been used as traditional therapeutic agent of leucorrhea mainly caused by Trichomonas vaginalis and Candida albicans. Sixty six kinds of crude drugs in ancient literatures and ten constituents were selected as sample drugs. Trichomycin standard was tested to compare with the above drugs. To determine the anti-fungal effect of these drugs on Candida albicans Yu 1200, a test organism, screening test was conducted. Antifungal activities of crude drug water extracts were observed by means of two test methods : firstly through the agar slant method and secondly the counting chamber method which was used for acknowledged drug agents upon the result of the agar slant method. And in order to improve the fungicidal effect, the organisms were stained with 0.02% methylene blue solution. The results of the above test indicated that Fritillariae Rhizoma has antifungal action in the concentration of 310mcg/ml, Coptidis Rhizoma in 620mcg/ml, Meliae Cortex, Scutellariae Radix both in 5,000mcg/ml. Baicalin, catechol among the pure isolated constituents inhibited in the range of 50mcg/ml. This score was based on 50% inhibition in comparison with amounts of control organisms. Rhei Rhizoma, Mori Radicis Cortex, Linderae Radix, and Amomi globosi Fructus showed the antifungal effect moderately in 5,000mcg/ml, and baicalein and pectolinarin in 50mcg/ml in the limit of between 35% and 50% antifungal activity. Staining with 0.02% methylene blue showed that any of the crude drug extracts was unable to stain the cells, but trichomycin in 0.86unit/ml able to stain 12% of the cells. This result means that crude drugs probably do not have fungicidal but fungistatic action.

  • To develope Hanbang beef jerky as health food, six kinds of beef jerky were prepared by adding sugar (A), licorice (B) and three kinds of spice extracts (clove: C, fennel fruit: D and Chungyang green pepper extract: E) and mixture of all extracts (F). The effects of the drying method and added spice extracts on the quality characteristics of the beef jerky were evaluated. In general, the air-blast dried beef jerky contained $31{\sim}33%$ moisture, $50.0{\sim}51.2%$ crude protein, $7.2{\sim}7.8%$ crude lipid and $3.0{\sim}3.3%$ crude ash. For the mineral content of the air-blast dried jerky, the most prevalent mineral was Na $(1540.08{\sim}1838.17$ mg%), followed by K, P, Mg, and Ca. The Ca content of the beef jerky was highest in the mixed extract group (88.53 mg%), and the lowest content was in sugar-added group (53.12 mg%). For the color properties, the L-value (lightness), a-value (redness) and b-value (yellowness) were higher in the air-blast dried beef jerky than in the hot air dried samples. The drying methods showed their greatest affect on the redness (a) for all six jerkies (p<0.001). For the preference by sensory evaluation, the beef jerky samples with added sugar (A) and licorice extract (B) had significantly higher scores than the beef jerky samples with the added spice extracts, for both of air-blast drying and hot air drying (p<0.05). Preference for the air-blast dried beef jerkies with added clove (C) and fennel fruits (D) were significantly higher, in terms of taste, color, softness and aftertaste as compared to the respective hot air dried jerkies (p<0.01). Considering all the obtained results, we concluded that licorice and spice extracts can be used as natural preservatives in the development of health foods and the air-blast drying method is recommended to improve the quality characteristics of beef jerky.

  • This study was conducted to increase crude protein and reducing sugar contents in pollen extracts by proteases. Four commercial neutral proteases (Alcalase 2.4L, Protamex, Flavozyme and Protease A) and two alkaline proteases (Protease S and Protease P) were used to prepare acorn and Darae pollen extracts. Contents of moisture, ash, crude protein and crude fat of acorn pollen were 5.2%, 2.7%, 6.2% and 22.3%, respectively, while those of Darae pollen were 5.4%, 2.8%, 1.8% and 27.8%, respectively. Contents of crude protein and reducing sugar in pollen extracts were increased by proteases. Alcalase 2.4L was the most effective in increasing protein contents while Protease A in increasing reducing sugar contents. It is suggested the use of proteases is one of the potential methods for increasing the contents of crude protein and reducing sugar in preparation of pollen extracts.

  • The composition of two Bokbunja (Rubus coreanus Miquel) wines (one without mushroom extracts (wine A) and the other is with the extracts (wine B)) has been investigated to improve the quality of Bokbunja wine. The content of solid particle, acidity, crude ash, crude protein of the wine A were 10.5%, 1.36%, 0.45% and 0.05% and those of wine B were 7.4%, 0.54%, 0.31%, and 0.22%, respectively. Crude fat and crude fiber were not detected in both samples. To verify the flavor quality of Bokbunja wine, the volatile components from ethylether extracts of two wines were analyzed using GC/FID and GC/MS. A total number of 12 volatile flavor compounds (6 alcohols, 3 ketones, 1 acid, 1 ester and 1 anhydride) were identified in the two Rubus wines. The major volatile compounds of the wines were 2,3-butanediol, 2,5-furanedione, phenylethyl alcohol, and butanedioic acid and they might affect the major role in the unique flavor of Bokbunja wines.
