  • Background: Leonurine is a the aerial part of Leonurus japonicus Houttuyn, which has been used as a traditional medicines and is registered in the Korean Pharmacopoeia. Methods and Results: In the present study we performed a heavy metals and thin layer chromatography and measured loss on drying, as well as the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine, using 15 domestically collected L. japonicus samples. The methods were performed according to the 'crude drugs test of the general test, processes and apparatus', published by MFDS, Korea (2014). The purity test (heavy metals) indicated that levels of Pb and Hg were 0.35 - 3.64, and 0.001 ppm, respectively, whereas the levels of As and Cd were undetectable, and stachydrine was identified by thin layer chromatography ($R_f$ : 0.15). We found that 5.93 - 10.62% (average: $8.58{\pm}1.8%$) of the sample mass was lost during drying, and the contents of total ash, acid-insoluble ash, ethanol soluble compounds, and leonurine were 7.87 - 10.84% (average: $9.62{\pm}0.82%$), 0.99 - 1.76% (average: $1.38{\pm}0.24%$), 16.70 - 23.11% (average: $19.49{\pm}2.14%$) and 0.04 - 0.17% (average: $0.11{\pm}0.04%$) respectively. In addition, HPLC profiling detected leonurine (5.94 min), rutin (16.43 min) and myricetin (26.78 min). Conclusions: We hope that this the rusult of the present study will contribute to the standardization and quality control of Korean herbal medicines.

  • The objective of this study was to estimate the food quality of commercial boiled-dried Pacific herring Clupea pallasi as a substitute for boiled-dried anchovy. Standards for controlling quality of boiled-dried Pacific herring were suggested based on international (US FDA and CODEX) and domestic (Korean FDA, Standards on Quality of Seafood and Seafood Products, KS) standards for boiled-dried anchovy. The standards included requirements for moisture [less than 30% (less than 35 in very tiny sizes)], water activity (less than 0.85), salinity (less than 10%), water-phase salt (less than 20%), acid-insoluble ash (less than 1.5%), yeast and mold (fewer than 1.0×103 CFU/g), and different size and breakage (less than 5%). Based on the standards suggested, commercial boiled-dried Pacific herring passed nine levels (all levels) in water activity, acid-insoluble ash, mold and yeast concentrations; seven levels (L-1, 2, 3, 4, M-1, 2, S) in water-phase salt, and three levels (L-1, 3, 4) in the ratio of different size and breakage categories. These results suggest that the quality of commercial boiled-dried Pacific herring is similar to that of commercial boiled-dried anchovy.

  • Berberis chitria (family Berberidaceae) has a close affinity with B. aristata, used in traditional systems of medicine as a drug 'Daruharidra' for skin disease, jaundice, affection of eyes, and rheumatism. Keeping this in view, in the present study attempts have been made to identify marker characters of B. chitria in order to differentiate the two species. Some of the diagnostic features of the root are patches of pericyclic fibre, pitted sclerieds and berberine containing cells and heterocyclic medullary rays. Besides, the physicochemical characters such as total ash; acid insoluble ash; alcohol and water soluble extractive; tannins; sugar and starch percentages has shown variations. The percentage of berberine as berberine hydrochloride was also calculated through HPTLC densitometric method and it was found little higher than B. aristata and B. asiatica i.e. 3.16%. Thus, this species can be utilized as a possible substitute to Daruharidra.

  • Objective: A study was conducted to determine the chemical composition of banana meal and rice bran from Australia or South-East Asia and test the hypothesis that there are no differences in rice bran produced in different countries, but there are differences between full-fat and defatted rice bran. Methods: Two sources of banana meal and 22 sources of rice bran (full-fat or defatted) from Australia or South-East Asia were used. All samples were analyzed for dry matter, gross energy, nitrogen, amino acids (AA), acid hydrolyzed ether extract (AEE), ash, minerals, total starch, insoluble dietary fiber, and soluble dietary fiber. Banana meal was also analyzed for sugars including glucose, fructose, maltose, sucrose, stachyose, and raffinose. Results: Chemical analysis demonstrated that banana meal from the Philippines is primarily composed of starch. Full-fat rice bran from Australia had greater (p<0.05) concentrations of AEE, lysine, and glycine than samples from the Philippines and Vietnam. Full-fat rice bran from Australia and Thailand had greater (p<0.05) concentrations of gross energy and most AA than rice bran from Vietnam. Full-fat rice bran from Australia had greater (p<0.05) concentrations of tryptophan and manganese than all other sources, but full-fat rice bran from the Philippines contained less (p<0.05) zinc than all other sources of rice bran. Gross energy, AEE, and copper were greater (p<0.05) in full-fat rice bran compared with defatted rice bran, but defatted rice bran contained more (p<0.05) crude protein, ash, insoluble dietary fiber, total dietary fiber, AA, and some minerals than full-fat rice bran. Conclusion: Banana meal is a high-energy source that can be used as an alternative ingredient in livestock diets. Full-fat rice bran from Australia and Thailand contained more concentrations of AEE and AA than samples from the Philippines or Vietnam. Full-fat rice bran had more gross energy and AEE than defatted rice bran, whereas defatted rice bran contained more crude protein, ash, and total dietary fiber.

  • Studies were carried out to investigate physicochemical properties of taro during the pretreatment process of making Toranbyung. Seventeen kinds of amino acids were found in taro. Aspartic acid and glutamic acid were most plentiful among those amino acids. Essential amino acids were about 42.7% of the total amino acids. Sulfur containing amino acids, mehtionine and cystine were about 2.7% The amylograph indicated that the initial temperature triggering gelatinization of both rice flour mixed with taro and glutinous rice flour mixed with taro increased as the amount of taro increased. But the maximum viscosity of rice flour mixed with taro did not increase as the amount of taroincreased while the maximum viscosity of glutinous rice flour mixed with taro increased as the amount of taro increased. And the peak temperature of both rice flour mixed with taro and glutinous rice flour miced with taro increased as the amount of taro increased. The alkali degree of insoluble ash was higher than that of soluble ash. Glutinous rice dough had more total sugar than rice dough. Yellowness of rice dough was higher than that of glutinous rice dough.

  • Physicochemical properties, intestinal microbial growth, and inhibitory effects of alcohol-insoluble polysaccharide (AIP) extracted from cucumber peel were investigated. AIP was composed of 14.54% crude protein, 1.04% crude lipid, 13.74 % crude ash, 9.1% soluble dietary fiber, and 41.2% insoluble dietary fiber. AIP showed low bulk density (0.18 g/mL) and water-holding capacity (6.39 g/g), and high oil-holding capacity (3.96 g/g). Pectic substance fractions [water-soluble pectic substance (WSP), ethylenediaminetetraacetic acid-soluble pectic substance (ESP), and alkali-soluble pectic substances (ASP)] and hemicellulose fractions [1 M KOH-soluble hemicellulose (KHP1) and 4 M KOH-soluble hemicellulose (KHP4)] were obtained from sequential chemical fractionation of AIP. WSP showed higher total sugar contents than total uronic acid contents, whereas opposite results were observed in ESP and ASP. Molecular weight distributions of three pectic substance fractions were in order of ASP>ESP>WSP. Ion exchange chromatogram pattern of WSP was different from those of ESP and ASP. Major component of WSP was fraction eluted by 0.05 M ammonium acetate buffer, whereas that of ESP and ASP was fraction eluted by 0.2 M NaOH. WSP and ASP showed growth-promoting activities against Lactobacillus brevis, Bifidobacterium bifidum, and B. longum, whereas B. bifidum and B. longum for ESP. KHP1 and KHP4 fractions had significant growth-promoting activities against B. bifidum.

  • This study was conducted to increase the quality of Astrragali radix and to decide the application amounts of N, P and K fertilizer for Astragalus membranaceus Bunge. The ferlilizers effect on the ash contents and extracts from the root and the dried root yield was studied. With increasing the application amount of nitrogen more than 5kg/10a, the acid insoluble ash content of root increased, but the ethyl alcohol and diethyl ether extracts decreased. No effect of phosphorus amount on the ash and extracts contents in root was observed. With increasing amount more than 7kg/10a, only the acid insoluble ash contents increased. The dried root yield increased with the application level until 5kg/10a of nitrogen, but the effects ot phosphorus and potassium application were not observed. Positive correlation was obtained significantly between the ash ($r=0.746^*$) and acid insoluble ash ($r=0.858^{**}$) contents and the potassium application amount, and the negative correlation was also obtained significantly between the extract contents and the nitrogen ($r=-0.778^*$ ; $C_2H_5OH$, $r=-0.848^{**}$ ; $(C_2H_5O)_2O$) and potassium ($r=-0.772^*$ ; $(C_2H_5O)_2O)$ application amounts. As the results in the first year from the seeding, it is recommended for quality of Astragali radix to apply 5, 7-14, 7kg/10a of N, $P_2O_5$ and $K_2O$, respectively.
