For the quality control of Cassiae Semen, anthraquinone compound, aurantio-obtusin, was isolated from the MeOH extract of Cassiae Semen (Leguminosae) and identified by the spectroscopic analysis. A quantitative analysis of aurantio-obtusin using HPLC method showed that the average contents of aurantio-obtusin were $0.03{\pm}0.01%$ in 50 samples collected throughout the various regions of Korea.

We examined the effects of biological activity Phellinus linteus mycelium culture with cassiae semen extract. Firstly, the optimal temperature, initial pH and culture period for mycelial growth in a liquid culture of P. linteus were determined, and they were $30^{\circ}C$, pH 5.0 and 8 days respectively. The five herbal materials were examined against several health functional efficacies, and, as a result, Cassiae semen was chosen, with its superior inhibitory effects in ${\beta}$-glucuronidase inhibitory activity, electron donating activity, ACE inhibitory, and ${\alpha}$-glucosidase inhibitory activities(95.3%, 80.9%, 96.1 and 24.2%, respectively). P. linteus fruit body was investigated on ${\beta}$-glucuronidase inhibitory activity, electron donating activity, ACE inhibitory, and ${\alpha}$-glucosidase inhibitory activities, and they were 54.7%, 81.9%, 30.0% and 20.1%, respectively. Accordingly, C. semen was used in the following experiment, to give an additive functional effect on the P. linteus. As the amount of C. semen in the cultural media increased, mycelial weight and ${\beta}$-glucan contents also increased, but final pH was not influenced. In addition, the ${\beta}$-glucuronidase inhibitory activity, electron donating activity, and ${\alpha}$-glucosidase inhibitory activity increased. P. linteus mycelium culture showed higher activities in the other three tests above, except for electron donating activity, when C. semen was added to the medium before cultivation.

Objectives : In this study, we investigated the effect of Cassia obtusifolia Linne (Cassiae Semen; CS) extract on ovalbumin (OVA)-induced allergic asthma in mice. Methods : CR was extracted with 70% ethanol. For in vitro study, HMC-1, human mast cells were treated with CS extract at 0.2 and $0.5mg/m{\ell}$ for 1 h, and then stimulated with compound (C) 48/80 for 30 min. Primary spleenocytes were isolated from the spleen of mice, treated with CS extract for 1 h, and then stimulated with ConA for 24 h. For in vivo study, mice were sensitized at day 0, 7 and 14 with 0.2% OVA and then airway challenged using neublizer at day 21, 23, 25, and 27 to induced allergic asthma. CS extract at doses of 100 and 300 mg/kg body weight was orally administered during OVA challenge once per a day. The levels of allergic mediators such as histamine, OVA-specific IgE, IL-4, and $IFN-{\gamma}$ were measured in the sera of mice or culture supernatants by EIA and ELISA, respectively. The expression of IL-4 and $IFN-{\gamma}$ gene was determined by RT-PCR. The histopathological change of lung tissues was observed with hematoxylin and eosin (H&E) and Periodic acid Schiff (PAS) staining. Results : The treatment of CS extract in HMC-1 cells significantly inhibited C48/80-induced degranulation, and histamine release. The treatment of CS extract in spleenocytes suppressed the expression of IL-4 and $IFN-{\gamma}$ mRNA. The administration of CS extract in OVA-induced asthmatic mice significantly decreased the levels of OVA-specific IgE, and IL-4 in a dose-dependent manner with OVA-control group. In addition, CS extract inhibited the infiltration of inflammatory cells and bronchiolar damage with epithelial thickening in lung tissues of OVA-induced asthma mice, and also mucin accumulation. Conclusions : These results indicate that CS extract prevents asthmatic damage through regulating the allergic immune response.

Cassiae Semen (seeds of Cassia tora) showed a remarkably different HPLC chromatogram after being treated with a crude enzyme extract from Aspergillus usamii. Increased and decreased compounds were identified as aurantio-obtusin and glucoaurantio-obtusin, respectively. The aurantio-obtusin content reached its maximum level ($133.58{\pm}0.39\;{\mu}g/mg$ extract) after being incubated for 50 min at $37^{\circ}C$, whereas the inactivated crude enzyme-treated control remained unchanged ($54.13{\pm}1.33\;{\mu}g/mg$). On the other hand, the glucoaurantio-obtusin content decreased by less than one-third ($51.09{\pm}1.63\;{\mu}g/mg$) ofthe untreated control ($143.19{\pm}2.12\;{\mu}g/mg$), suggesting that an increase in aurantio-obtusin content originated from the enzymatic cleavage of its glucoside glucoaurantio-obtusin.

In terms of regulatory toxicology, especially for the traditional Chinese medicines, problems can be arise from a fact that there is no distinctive barrier between herbal drugs and food/beverage. An example is that many kinds of Chinese herbal materials have been also used as tea materials in Korea, China, Japan and Vietnam. Sixteen tea materials (also used as herbal materials) were extracted with 70% ethanol and the extract further partitioned with chloroform and water. Those ethanol extract and fractions were subjected to the SOS-Chromotest to examine potential mutagenicity. It was found that ethanol extract of Chaenomelis Fructus (Chaenomeles japonica Lindley, 木瓜, Rosaceae) and both ethanol extract and water fraction of Cassiae Semen (Cassia tora Linne, 決明子, Leguminosae) showed relatively high mutagenic activities in SOS-Chromotest.

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.

식중독 원인균에 대해 결명자(Cassiae semen), 가시오가피(Acanthopanacis cortex), 당귀(Angelica gigas)는 $7{\sim}10mm$의 항균력을 나타내었으며, 야콘 추출물은 10mm의 항균력을 나타내었다. 특히 Staphylococcus aureus KCTC 1927에 대해서는 사용한 약재 성분들이 전반적으로 높은 항균활성을 나타내었다. 또한 야콘 잼을 제조한 결과, 연초록색의 상품가치가 높은 맛있는 잼을 얻을 수 있었다. 관능평가에 있어서 야콘잼은 조직감이 우수하여 딸기잼 보다 높게 평가되었으며 또한 색도 우수한 것으로 평가되었다. 잼의 견고성과 젤 강도는 딸기, 딸기+알로에 베라, 야콘+알로에 베라, 야콘 잼의 순서로 나타났고, 이는 oligosaccharide 첨가의 영향이라 볼 수 있다. 야콘 잼의 기능성과 효능을 감안해 볼 때 앞으로 일반화되면 소비자의 선호도가 높을 것으로 추측되며, 비만과 당뇨병 환자도 안심하고 섭취할 수 있는 기능성 식품이라고 생각된다.
