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 roasting condition and organoleptic characteristics in Cassia tora tea were investigated. Intact Cassia tora seeds were composed of water 11.6%, crude protein 13.1%, crude fat 4.4%, crude fiber 13.8%, N-free extract 47.2% and ash 4.9%. Organoleptic qualities in Cassia tora tea were sweetness, astringency, tartness, bitterness, roasted coffee like, roasted barley like and burnt smell. Organoleptic qualities were investigated by descriptive analysis method, too. Overall acceptability was increased by roasting but it was low because of formation of bitterness and burnt smell at excessive roasting conditions. Sweetness was the most important factor in organoleptic quality of Cassia tora seeds and the optimum condition for the best quality was $210^{\circ}C$, 20 minutes.

Cassia tora L. seeds have previously been reported to reduce blood glucose level in human and animals with diabetes. In the present study, the effects of Cassia tora L. seed butanol fraction (CATO) were studied on postprandial glucose control and insulin secretion from the pancreas of the normal and diabetic rats. Diabetes was induced by an i.p. injection of Streptozotocin (55 mg/kg BW) into the male Sprague-Dawley rats. The postprandial glucose control was monitored during a 240 min-period using a maltose loading test. In normal rats, rats fed CATO (20 mg/l00 g BW/d) showed lower postprandial glucose levels in all the levels from 30 min up to 180 min than those in the control rats without CATO (p<0.05). In diabetic rats, those levels in the CATO group seemed to be lower during the $30{\sim}180$ min, but only glucose level at 30 min showed significant difference compared to that in the control group. Moreover, CATO delayed the peak time of the glucose rise in both normal and diabetic rats in the glucose curves. On the other hand, when CATO was administered orally to the diabetic rats for 5 days, 12 hr fasting serum glucose level was decreased in the diabetic rats (p<0.05). Degree of a decrease in 12 hr fasting serum insulin levels was significantly less in the diabetic CATO rats as compared to diabetic control rats. On the last day of feeding, P cells of the pancreas were stimulated by 200 mg/dL glucose through a 40 min-pancreas perfusion. Amounts of the insulin secreted from the pancreas during the first phase ($11{\sim}20$ min) and the second phase ($21{\sim}40$ min) in the CATO fed diabetic rats were significantly greater than those in the diabetic control group (p<0.05). These findings indicated that constituents of Cassia tora L. seeds have beneficial effect on postprandial blood glucose control which may be partially mediated by stimulated insulin secretion from the pancreas of the diabetic rats.

A methanol extract of Cassia tora seeds was successively partitioned with diethyl ether, chloroform, ethyl acetate, and water, and the antitumor-promoting activity of the solvent fractions was determined by inhibition of Epstein-Barr virus early antigen (EBV-EA) activation induced by teleocidin B-4 in Raji cells. The diethyl ether (68.7%) and chloroform (91.2%) fractions and the hydrolysate (94.3%) of the ethyl acetate fraction had strong inhibitory activities. The chloroform and ethyl acetate fractions were chromatographed on silica gel and further purified by HPLC. Three active compounds, obtusifolin-2-glucoside (75.0%), chryso-obtusin-6-glucoside (56.8%), and norrubrofusarin-6-glucoside (39.4%), were obtained from the ethyl acetate fraction, and two active compounds, questin (97.9%) and chryso-obtusin (53.8%), were isolated from the chloroform fraction.

In this paper we consider the TORA system and use backstepping to design active controllers for tracking; this problem is much more challenging than stabilization. We show that the control effort of the closed-loop system can be significantly improved by exploiting the backstepping design.

Radical scavenging principles on 1, 1-diphenyl-2-picylhydrazyl(DPPH) radical were isolated from the seeds of Cassis tora L. Assignments of the^1H-{\;}and{\;}^{13}C-NMR$ data showed the active components to be an anthraquinone, alatemin nad two naphthopyrone glycosides, nor-rubro-fusarin-6-.betha.-D-glucoside(cassiaside) and rubrofusarin-6- -D-gentiobioside. Altemin showed more potent radical sacvenging effect than the others.

Three naphthopyrone glucosides, cassiaside (1), $rubrofusarin-6-O-{\beta}-D-gentiobioside$ (2), and $toralactone-9-O-{\beta}-D-gentiobioside$ (3), were isolated from the BuOH-soluble extract of the seeds of Cassia tora as active constituents, using an in vitro bioassay based on the inhibition of advanced glycation end products (AGEs) to monitor chromatographic fractionation. The structures of 1-3 were determined by spectroscopic data interpretation, particularly by extensive 1D and 2D NMR studies. All the isolates (1-3) were evaluated for the inhibitory activity on AGEs formation in vitro.

The purpose of this study was to investigate effects of chestnut inner skin tea, brown rice-green tea and Cassia lora tea on the activation of physiological functions (regional cerebral blood flow, mean arterial blood pressure, proliferation of immunocytes in vitro and in vitro, suppression of cancer cell proliferation) in mouse and rat. We used 8 weeks-old balb/c male mice, 300g ICR rats and L1210 cell lines. Regional cerebral blood flow(rCBF) and mean arterial blood pressure(BP) were measured using Leser-Doppler Flowmetry(LDF) and the proliferation of cells was measured using a colorimetric tetrazolium assay(MTT assay). The experimental results are as follows : 1. rCBF was increased by Cassia tora tea, but decreased by chestnut inner skin tea in rats. 2. BP was increased by brown rice-green tea in rats. 3. Proliferation of mouse thymocytes and splenocytes were significantly increased by chestnut inner skin tea in vitro. 4. Proliferation of mouse thymocytes was decreased by Cassia tora tea and brown rice-green tea in vitro. 5. Proliferation of mouse thymocytes was decreased by Cassia tora tea and brown rice-green tea in L1210 transplanted mice. 6. Proliferation of splenocytes was accelerated by chestnut inner skin tea in L1210 transplanted mice. 7. Proliferation of L1210 cells was inhibited by chestnut inner skin tea and Cassia tora tea in L1210 transplanted mice.

The effects of roasting Cassia tora L. were investigated for proximate composition, color, volatile flavor profile, microbial growth and alcohol fermentation. While moisture, protein and fat contents decreased with increasing roasting temperature, fiber and ash contents increased. The L, a and b values of Cassia tora L. extracts decreased with increasing temperature, and only a small difference in total color difference$({\Delta}E)$ was observed. A little difference in major flavor components between raw and roasted treatment was found during roasting. Furfuryl alcohol, a major component of coffee flavor, was separated from Cassia tora L. extracts extracted with ethyl ether. The yeast growth was the highest on the water-extract of Cassia tora L. roasted at $160^{\circ}C$. With increased levels of water-extract at $160^{\circ}C$, S. cerevisiae grew rapidly for 24 hr incubation and the growth rate was higher than the unroasted control group. The growth rate of Bacillus subtilis was the highest in a treatment of 0.5% concentration. Little differences in ${\alpha}-amylase$ produced from Bacillus subtilis were observed among the treatment groups. The total alcohol content increased with increasing roasting temperature during alcohol fermentation.
