  • Cassia obtusifolia L. is commonly used as medicinal foods to treat gastrointestinal disease in many countries. This study evaluated the anti-constipation effects of ethanolic extract of Cassia obtusifolia L. in rats with loperamide-induced constipation. Diffferent concentrations of ethanolic extract of Cassia obtusifolia L. (0, 10, 250, and 500 mg/kg) was administered to rat orally once daily for 3 weeks following loperamide treatment. Six-week-old Sprague-Dawley rats (N=25) were randomly divided into five groups: normal control and experimental groups and injected loperamide intraperitoneally to induce constipation in the latter four experimental groups. Following the induction of loperamide-induced constipation, a marked decrease was observed in the fecal weight and water content discharged for over 1 week and intestinal transit time while an increase was observed in the number of fecal pellets remaining in the colonic lumen as compared with the normal control group. These conditions were significantly alleviated following the administration of the two doses (250 and 500 mg/kg) of ethanolic extract of Cassia obtusifolia L. when compared to the loperamide-treated (constipation control) group. More specifically, the number of fecal pellets in the colon was 3, 5, 4, 2.8, and 1.2 in the five groups, respectively and the corresponding GIT ratio was 70.77, 56.59, 58.67, 66.81, and 72.10%, respectively. The fecal water content, transit distance, and GIT ratio in the high-dose treatment group were significantly higher than that in the medium-dose treatment group, but a significant decrease in the number of fecal pellets in the colon. In conclusion, the Cassia obtusifolia L. extract is suggested to have beneficial effects as a therapeutic and preventive strategy to alleviate constipation and to relieve the symptoms of constipation such as pain, flatulence, distention, bloating, and unpleasant taste.

  • Fungicidal activities of Cassia obtusifolia extracts and their active principles were tested against Botrytis cinerea, Erysiphe graminis, Phytophthora infestans, Puccinia recondita, Pyricularia grisea, and Rhizoctonia solani, and compared with synthetic fungicides and two dihydroxyanthraquinones. At 1 g/l, the chloroform fraction of C. obtusifolia extracts showed fungicidal activity against B. cinerea, E. graminis, P. infestans, and Py. grisea, and the ethyl acetate fraction showed fungicidal activity against E. graminis and P. infestans. Danthrone was chromatographically isolated from the chloroform fraction and showed fungicidal activity against B. cinerea, E. graminis, P. infestans, and Py. grisea with 68, 100, 78, and $91\%$ control values at 0.5 g/l, respectively. Specifically, alizarin and quinizarin inhibited E. graminis, P. infestans, and Py. Grisea, but did not inhibit the growth of P. recondita and R. solani. These results indicate at least one of the fungicidal actions of danthrone.

  • Tacrine is an acetylcholinesterase inhibitor that is approved for the treatment of Alzheimer's disease. However, tacrine treatment for Alzheimer's disease results in reversible hepatotoxicity in 30-50% of patients, which seriously limits its clinical use. Accordingly, the identification of constituents in natural products that have protective effects on tacrine-induced hepatotoxicity would be valuable. In the present study, an immortalized human hepatoma cell line, HepG2 was employed to screen for agents that protect against tacrine-induced hepatotoxicity. The bioassay-guided fractionation of water extract of Cassiae Semen furnished two anthraquinones, aurantio-obtusin (1) and obtusifolin (2). Compounds 1 and 2 showed hepatoprotective effects with the protection ratio values of 55.3 +/- 0.5% and 41.2 +/- 0.8% at $160{\mu}M$, respectively.

  • This study was conducted to investigate how a labor saving for conventional hand sowing and respond to major agronomic traits under different planting density in 1993 and 1994. Each trial was a randomized block split plot with row spacing as the main plots and hill spacing as subplots. Sowing rate appeared lower in 20 or 25cm hill spacing using machine seeder than in hand sowing. Sowing time required reduced more 121 hours per hectare in 60cm row, 20cm hill spacings using machine seeder than in hand sowing. Increasing row and hill spacings reduced number of seedling stand per unit $area(m^2)$. Both number of pods per plant and grain weight per plant and showed highly increase in wide planting. Best yield obtained in 60cm row, 20cm hill spacing using machine seeder. Accumulative mean air temperature was positively correlated with stem height, number of pods per plant and yield, otherwise accumulative rainfall was negatively correlated with ones. A highly significant negative correlation was showed between number of seedling stand per unit $area(m^2)$ and number of branches, number of pods per plant, grain weight per plant and yield. Yield was positively correlated with number of branches, number of pods per plant and grain weight per plant.

  • The Aims of this study are to investigate ecological environments and indoor-rearing conditions of Eurema hecabe for artificial rearing. Two different nesting site, a open area nearby small river(A area; Daejin-ri, Gonyang-myeon, Sachun-si, Gyoungsangnam-do) and a foot of a hill area(B area; Noryang-ri, Seolcheon-myeon, Namhae-gun, Kyoungsangnam-do), selected for investigation of ecological habitat environment, and investigated two times per month, during six month, from June to November in 2010. In result, the number of butterflies, Eurema hecabe, at the hill area(B area) was 6 times more than the open area(A area). We observed the number of eggs, larvae and puapae in the B area more times compared to those in the A area. In the B area, Lespedeza cuneata was higher preference than the other host plant, Lespedeza pilosa and Albizia julibrissin. For development of indoor-rearing conditions, common grass yellow butterfly, Eurema hecabe, was reared in a room condition. As a result of oviposition preference experiment, 100-mated-female laid significantly higher number of eggs $104.9{\pm}19.6$ on Lespedeza cuneata plant, whereas the number of eggs was $12.7{\pm}4.5$ on Cassia obtusifolia plant. Moreover, the eggs hatched within $5.1{\pm}0.9$ days from the day of oviposition and procent of egg hatchability was 53.7% on host plant. The headwidth of each developmental larval stage were $0.36{\pm}0.02$(1st), $0.61{\pm}0.02$(2nd), $0.93{\pm}0.05$(3rd), $1.46{\pm}0.08$(4th), $2.25{\pm}0.11$(5th). The larval period was $12.1{\pm}0.9$ days under high temperature, long day condition($25^{\circ}C$, 16L : 8D), showing 81.0% pupal ratio. The pupal period was $6.9{\pm}0.7$ days, and the emergence rate was 79.6%. Based on above experiment, artificial rearing system of common grass yellow butterfly, Eurema hecabe was completed in indoor condition.
