  • In India, Gymnema sylvestre due to the unique property of the plant to antagonize the sweet taste is known as 'Gur-mar'. It has several ethnomedicinal values as various tribals/traditional communities and rural peoples of India find diverse medicinal uses viz. antidiabetic, stomachic, diuretic, and is useful in cough and throat troubles. Besides, it has strong effect on reducing blood sugar. The present communication deals with the detailed pharmacognostical evaluation of the aerial parts of G. sylvestre collected from three places of the country-Varanasi (U.P), Panchmarhi (M.P), Salem (Tami Nadu) and commercial sample procured from local market. The botanical and physico-chemical parameters of all the samples were quite similar though little variations were observed in foaming index, alcohol and water soluble extractives of local sample. The microscopic characteristics of the drug are horse shoe shaped petiole with 3 amphicribal vascular bundles, sieve tubes well developed; anomocytic stomata only on the abaxial surface of the leaf, the fan shaped amphicribal vascular bundle, presence of intraxylary phloem. The TLC fingerprint profile of all the samples was more or less similar only the quantity of some of the compounds varied.

  • This study investigated the quality characteristics and antioxidant activities of Makgeolli (a traditional Korean rice wine) made with Etteum bell flower root (0.5, 1, 1.5, and 2% with steamed rice) during fermentation. The pH values of Makgeolli with Etteum bell flower root powder decreased after 3 days of fermentation and then increased after 5 days of fermentation. Sugar content decreased after 3 days of fermentation. Color evaluation showed the L values of these drinks decreased during fermentation, whereas a and b values both increased. The alcohol content of Makgeolli increased after fermentation, reaching a maximum concentration of 7.90-8.07% by the end of fermentation. Total phenolic compound contents and DPPH radical scavenging activities increased as the ratio of Etteum bell flower root increased. Sensory scores of Makgeolli fermented with 1.5% Etteum bell flower root ware greater than those of Makgeolli prepared by other treatments. Therefore, Makgeolli added with 1.5% Etteum bell flower root added considered to be the most suitable for manufacturing.

  • To evaluate the characteristics of modified nuruk made by inoculation and cultivation of Rhizopus jap-onicus T2, Aspergillus oryzae L2 and hansenula sp. BC26 three different Takju mashes were made with modified Nuruk commercial Nuruk and rice koji and the changes in microorganisms and major compon-ents of mashes were investigated uring brewing. The numbers of yeast kept higher in the mash of mod-ified Nuruk or rice koji. The numbers of lactic acid bacteria were high in mash of commercial Nuruk but those were not in mash of modified Nuruk or rice koji. all mashes showed stable pH in a day and the pH kept higher in mash of modified Nuruk than in that of commer-cial Nuruk or rice koji. Increase in the content of total acid was moderate in mash of modified Nuruk or rice koji but it was too much in that of commercial Nuruk. increase in the content of amino acid was much highr in mash of modified Nuruk or commercial Nuruk than in that of rice koji. Increase in the content of alcohol was more rapid in mash of modified nuruk or rice koji than in that of commercial Nur-uk. The content of reducing sugar kept highter in mash of commercial Nuruk or modified Nuruk than in that of rice koji. A small amount of modified Nuruk accomplished favorable fermentation showing nor-mal patterns in microbiological and physicochemical changes during brewing.

  • Onion vinegar, which has an undesirable flavor and taste formed through alcohol and acetic acid fermentation, possesses additives that can improve sensory quality. Thus, the objective of this study was to present an optimized blending ratio using response surface methods for an onion vinegar beverage by adding Omija extracts. This study was performed to formulate an Omija-onion vinegar beverage (OOVB) and investigate its antioxidant properties and antimicrobiological effects. The experimental design was conducted using an optimal mixture model of response surface methodology which generated eighteen experimental trials with overall acceptance as the responses. According to the statistical analyses, OOVB demonstrated a ratio containing onion vinegar, water, brown sugar, apple extracts and Omija extracts of 10, 72.3, 4.4, 12.2 and 1.1 (weight ratio), respectively. The OOVB revealed desirable nutrition values (phenolics compounds 19.3 mg/100 g, total flavonoids 3.1 mg/100 g, quercetin 1.9 mg/100). The OOVB displayed antibacterial effects in Gram negative Enterobacter aerogenes, Escherichia coli, Salmonella typhimurium and Gram positive Staphylococcus aureus. The findings revealed that OOVB was 18% in DPPH radical inhibitionand 11% in superoxide dismutase-like activity thus, OOVB has nutritional value and good quality as well as potential biological activities for functional beverages.

  • This study examined the chemical composition of A. blasiliensis and the chemical structural properties of an immuno-stimulating polysaccharide. The amino acids, free sugars, and organic acids by HPLC and fatty acids by GC were analyzed. The immuno-stimulating substance from A. blasiliensis was extracted with hot water and purified by ethanol precipitation. It underwent ion exchange chromatography on DEAE-cellulose and gel filtration on Toyopearl HW 65F. Through GP-HPLC, the substance was found to be homogeneous. Its chemical structure was determined by $^{13}C-NMR$. Fatty acids, organic acids, and sugar alcohol composition consisted exclusively of linoleic acid, fumaric acid and mannitol, respectively. The amino acids were mainly glutamic acid, glycine, and arginine. By $^{13}C-NMR$ analysis, the immuno-stimulating substance was identified as ${\beta}-(1{\rightarrow}3)\;(1{\rightarrow}6)$-glucan, composed of a backbone with $(1{\rightarrow}3)$-linked D-glucopyranosyl residues branching a $(1{\rightarrow}6)$-linked D-glucopyranosyl residue. The ${\beta}$-glucan from A. blasiliensis showed pronounced immuno-stimulating activity on the antibody-production ability of B-lymphocytes by the hemolytic suspension assay. In these results, A. blasiliensis was estimated to have potent pharmacological properties and potential nutritional values.

  • 녹말로부터 에탄올을 직접 생산하는 균주를 개발하고자 amylase 활성이 높은 Aspergillus oryzae와 알콜발효능이 있는 Saccharomyces cerevisiae의 원형질체를 융합하였다. 이들의 융합을 유도하기 위해서 fusogen으로 35% PEG 4000을 사용하였으며, 융합체의 선별을 위한 유전적 지표로는 아미노산 요구성을 사용하였다. 융합률은 $4.6\times 10^{-6}$이었다. 선별된 융합체들은 효모의 형태였으며 amylaseghkf성을 나타내었고, 에탄올을 생사하였다. 그리고 이들 성질 중에서 형태는 후세대에도 안정하게 유지되었으나 녹말로부터의 알콜 생성능은 현저히 감소하였다. 비록 포도당 배지에서의 융합체들의 알콜 생산은 S. cerevisiae의 0.5배에 지나지 않았으나, Prototroph인 S. cerevisiae와는 달리 이들은 녹말로부터 직접 에탄올을 생산할 수 있었다.
