Background: Constipation is one of the most common functional gastrointestinal disorder. The present study examined the ability of water extract of fermented (FRC) and non-fermented (NFRC) roasted Cassia tora to improve intestinal function and reduce constipation in a rat constipation model. Methods and Results: Different concentration of FRC and NFRC were orally administered loperamide (5 mg/kg; LOP) reduced the number, weight, and water content of feces, as well as intestinal transit motility. However, 24 h-(24 hour fermented roasted-Cassia tora) 300 mg/kg FRC administration increased the number, weight, and water concent of feces, compared to that seen in the LOP group, and also improve intestinal transit mitility and, the thickness of distal colon and mucous fluid. Conclusions: The results of the present study indicated that LOP-induced constipation was improved by treatment with FRC. Therefore FRC could be used to develop functional foods or natural medicine for constipation. However, further study is needed to clarify how fermentation improves the medicinal properties of roasted C. tora.

The effects of roasting temperature and time on the antioxidant activities of Cassia tora L. were investigated. In comparison with raw seeds (7.15 mg TAE/g), roasted seeds contained a significantly higher total polyphenol content (p<0.05). However, seeds roasted at a higher temperature ($250^{\circ}C$) for 10 min showed a significantly lower total polyphenol content (2.30 mg TAE/g; p<0.05). The electron donating abilities of Cassia tora L. seeds increased with an increase in roasting time; further, seeds roasted for 5 min at lower temperatures showed higher electron donating abilities (80.61% at $175^{\circ}C$; 80.75% at $200^{\circ}C$) than did seeds roasted for 5 min at higher temperatures (76.26% at $225^{\circ}C$; 77.35% at $250^{\circ}C$). Seeds roasted at lower temperatures showed adequate L values, regardless of roasting time; by contrast, seeds roasted for 10 min at higher temperatures, showed markedly lower L values. Our results indicate that roasting temperature and time must be controlled to produce high-quality Cassia tora L. products.

Background: Cassia tora L., an annual or perennial plant of the Fabaceae family, is traditional medicine with various biological activities, including anti-constipation and, anti-inflammation. Chemical compounds such as anthraquinone glycoside and naphthalene derivatives have been isolated from this plant. Cassia tora L. is a common contaminant of agricultural commodities, but is toxic to cattle and poultry. Methods and Results: To investigate the potential toxicity, Cassia tora L. aqueous extract (CO) was administered orally to rats for 26 weeks at 0 (control), 300, 1,500 and 3,000 mg/kg/day (n = 10 for male rats for each dose). The positive control comprised animals orally administered anthraquinone 100 mg/kg/day. There was no treatment-related mortality. An increase in the kidney weight was observed at 3,000 mg/kg/day of CO and anthraquinone 100 mg/kg/day. Macrophage infiltration in the colon was observed at CO 1,500 and 3,000 mg/kg/day and anthraquinone 100 mg/kg/day, but there were no significant toxicological changes in the incidence and severity of the finding. Conclusions: The oral no-observed-adverse-effect level (NOAEL) of CO was 3,000 mg/kg/day in male rats and no target organs were identified. In addition, 300 mg/kg was found to be the no-observed-effect level (NOEL) for systemic toxicity under the conditions of the study.

The present study was undertaken to evaluate the anti-hyperlipidemic activity of Albizzia julibrissin and Cassia tora L. extract mixtures in high fat diet-induced hyperlipidemic rats. In high-fat diet fed hyperlipidemic rats, oral treatment with Albizzia julibrissin and Cassia tora L. extracts resulted in decreased levels of total serum cholesterol and triglycerides, epididymal fat pad (EFP) weights, and activities of hepatic glucose-6-phosphate dehydrogenase (G6PDH) and malic enzyme, while the levels of feces production and high-density lipoprotein (HDL)-cholesterol were increased, compared with untreated control. Therefore, these results suggest that Albizzia julibrissin and Cassia tora L. extract mixtures can ameliorate hyperlipidemia.

The purpose of this study is to investigate the effect of raw Cassia tora L. powder added-diets on reducing cadmium accumulation in rats. The experimental animals were Sprague-Dawley family(♂, 4 weeks) which was classified into normal group CN, compared group CS, Cd-added group Cl and groups C2, C3, C4 in which 0.5, 1.0 and 1.5% of the Cassia tora L. powder are added, respectively. The growth rate and food efficiency ratio, and the amounts of accumulated cadmium in rats for S weeks were measured and analyzed. The results are as follows; 1. The rates of weight gain decreased in the order of C3>C2>C4>Cn>Cs>Cl groups, and Cl group to which only cadmium water had been fed was the lowest among them. The correlation between groups Cl and C3 was significantly different at the 1% level. 2. Food efficiency ratio(FER) decreased in the order of C3>C2>Cs>Cn>C4>Cl, and the FERs of C3, C2, CS, CN and C4 are greater than that of Cl by 22.87, 19.59, 18.54, 14.20 and 13.17%, respectively. 3. As for the Cassia tora L. powder-added groups, the amounts of cadmium accumulated in organs and tissues, that is, the brain, heart, spleen, liver, lungs, testicles. kidney, femoral muscle and leg bones were 0.45 $\pm$ 0.04 to 0.83$\pm$0.04, 1.68$\pm$0.02 to 2.16$\pm$0.02, 3.26$\pm$0.05 to 4.62$\pm$0.27, 37.52$\pm$0.09 to 47.71$\pm$0.73, 1.07$\pm$0.10 to 1.66$\pm$0.04, 1.04$\pm$0.06 to 1.24$\pm$0.08, 36.79$\pm$0.20 to 39.61 $\pm$0.53, 0.87$\pm$0.02 to 1.00$\pm$0.02 and 0.65$\pm$0.17 to 1.27 $\pm$ 0.06 $\mu\textrm{g}$/g, respectively. 4. The accumulated Cd content for C4 was the lowest among Cassia tora L. powder-added groups. When the results for C4 are compared with those for Cl, it is observed that each cadmium content accumulated in the brain, heart spleen, liver, lungs, testicles, kidney. femoral muscle and leg bones is dropped by 49.03, 22.56, 36.02, 35.75, 41.75, 36.20, 37.00, 22.77 and 56.67 %, respectively.

In order to determine the optimum sowing date of Cassia tora L., ecological characters, components and yield were investigated under vinyl-mulching and non-mulching condition. Emergence date and maturation date of vinyl-mulching condition were earlier than those of non-mulching condition. especially with maturation date being about 30 days earlier, Under vinyl-mulching condition, length of stem and pod were longer, number of branches, pods and seeds per plant were increased, stem diameter was thicker, and weight of 1000 grains was heavier. Seed yield per 10a under vinyl-mulching was twice as high as that of non-nulching condition. As sowing date was delayed, the maturation date was progressively delayed. At sowing date of April 10, plants showed the longest in length of stem and pod, the largest in number of pods per plant and number of grains per pod, and the highest in weight of 1000 grains and seed yield. Judging from the results, optimum sowing of Cassia tora L. appeared to be April 10.

The growth of weeds and some other plants has been considered to be inhibited by sicklepod(Cassia tora L.) sharing the habitat. The study was conducted, for the first time, to propose that this phenomenon is not only due to competition for physical and nutritional conditions but also due to allelopathy. In addition, autotoxicity of sicklepod was examined. The results are summarized as follows. 1. Rice sheath length reduced progressively from 18 % to 36 % with increasing the concentration of treating aqueous extracts of sickle pod seeds, but rice germination was not affected. In contrast, radish hypocotyl length was not reduced by the aqueous extract treatment but radish germination was significantly reduced by 66 % at 1 : 10 and 1 : 5 treatment. 2. Total chlorophyll contents in rice seedling decreased from 50 % to 65 % by treatment of seed aqueous extracts diluted from 1 : 50 to 1 : 5 ratio. 3. Aqueous extracts of sicklepod leaves significantly reduced hypocotyl length and fresh weight in radish and germination in rice, but mung bean was slightly affected by aqueous extracts only in fresh weight. 4. Volatiles from fresh, immature seeds with husk reduced the radish germination and seedling growth and radish root growth appeared to be more sensitive to the exposure to volatiles from fresh immature seeds than both germination and hypocotyl growth. 5. Volatiles from sickepod leaves inhibited germination and growth of radish, rice and mung bean, and seedling growth was more sensitive to volatiles from leaves than germination. 6. Volatiles from sicklepod leaves reduced germination and radicle length of sicklepod itself. 7. Collectively, it is concluded that there are water-soluble and volatile substances responsible for allelopathy in sicklepod.
