Soybean sprouts are the third-most consumed vegetable in Korea. Several studies on cultivation techniques, including use of medicinal plants extracts, have been performed to enhance the quality and yield of soybean sprouts. The objective of the present study was to investigate the effect of lacquer, a medicinal plant extract, on the yield and nutritional value of soybean sprouts. Linolenic acid content was significantly (p<0.05) increased in the sprouts produced by soaking seeds in lacquer extract diluted with equal volume of water. Lacquer extract significantly increased the flavonoid and phenolic contents (p<0.05). The content of total free amino acids, including ${\gamma}$-aminobutyric acid, was higher in lacquer extract-treated sprouts than in the untreated control. Results of this study suggest that lacquer extract could be used for enhancing the yield and nutritional values of soybean sprouts.

Sphaeranthus africanus is commonly used as a traditional remedy for sore throats and pain treatment in Vietnam. The aerial parts have been studied for its anti-inflammatory and anti-proliferative properties. However, the antioxidant and antidiabetic potential of the plant has not been explored. In this work, hydrophilic extracts of the plant's aerial parts were prepared in order to investigate its antioxidant and anti-diabetic properties. Also, the cytotoxicity of the root was evaluated and compared to that of the aerial parts. All of the extracts inhibited lipid peroxidation with IC₅₀ values ranging from 2.05 to 3.56 ㎍/mL, indicating substantial antioxidant activity. At an IC₅₀ value of 4.80 ㎍/mL, the 50% ethanol extract exhibited the most potent inhibition of α-glucosidase. The cytotoxic activity of root extracts is 2 to 5-fold less than that of the aerial parts. Nevertheless, dichloromethane and ethyl acetate extracts of the root demonstrated a selective effect on leukemia cells, with no harm towards the normal HEK-293 cell line. This work provides a scientific support for the antioxidant and antidiabetic activity of the plant. Hence, it may find a promising material for the development of novel antioxidant and antidiabetic agents. More research can be conducted on the phytochemistry and anticancer activities of the plant's root.

The anticancer effect of medicinal plants against two oral carcinoma cells, A253 and SCC-25 were investigated in this study. Methanol extracts from 63 medicinal plants, which have anticancer activities against other cancers such as stomach, hepatocellular or colon carcinomas, were prepared and screened for their anti- oral cancer activity by using MTT assay. Thirty one samples showed anti-oral cancer activity against either cell line used, however, other 32 samples had no anti-oral cancer activity. Among these samples methanol extract of Caesalpinia sappan revealed the strongest anti-oral cancer activity. The $IC_{50}$/ values of this extract against A253 and SCC-25 cells were 16 and 25 $\mu$g/m1, respectively. Fractions of n-hexane, dichloromethane, ethylacetate, n-buthanol and water were prepared from methanol extracts of Caesalpinia sappan, Anthriscus sylvestris, Rhus japonica, Curcuma arowatica, Inula helenium, Sinoarnudinaria reticulata, and Polygonum cuspidatum, respectively. Among these 35 fractions the n-hexane fraction of Inula helenium showed the strongest anti-oral cancer activity, the $IC_{50}$/ value was 1.6$\pm$0.3 $\mu\textrm{g}$/ml. Ten other fractions showed $IC_{50}$/ values lower than 10 $\mu\textrm{g}$/ml.

Purpose::This study aims to analyze the management performance and production efficiency of medicinal crop farmers. Methods: We conducted an empirical survey of medicinal crop farmers and analyzed production efficiency using DEA method. Results: First, The crops that increased the number of farms during 2010 and 2018 were Angelica tenuissima and Salvia miltiorrhiza, which was attributed to higher income per hour than other crops. Second, As for the efficiency of Liriope platyphylla, the average was 0.376, and the coefficient of variation was the lowest, 0.566. Third, Salvia miltiorrhiza and Atractylodes japonica had the highest technical efficiency after Liriope platyphylla, but the variation coefficient was high and the efficiency was relatively high. Fourth, As a result of performing variance analysis to find out the difference of each crops on the value of medicinal crop efficiency, the technical efficiency, pure technical efficiency, and scale efficiency were all statistically significant. Conclusion: Based on the results above, following policy suggestions are offered. First, It is necessary to provide information on crops with high income compared to the input of labor, and to develop labor-saving cultivation technologies for each crop. Second, A stable labor supply system will be needed in rural areas. Third, Efforts should be made to close the technological gap between farmers through a lot of education and consulting for farmers who grow medicinal crops.
