Alismatis Rhizoma has been used as diuretics and antiphlogistics in the Chinese oriental medicine. A trypsin inhibitor was isolated from Alismatis Rhizoma using DEAE ion exchange column, trypsin affinity column, and FPLC chromatography, and its activity and characteristics were studied. The purifed Alismatis Rhizoma trypsin inhibitor (ARTI) was estimated to be about 22 kDa. The sequence determination on N-terminal amino acid residues and 84 amino acid residues has been completed, yet no homology has been found with trypsin inhibitors reported at NCBI. ARTI did not show inhibitory activities on chymotrypsin and elastase, however it exhibited a significant inhibitory activity on bovine trypsin, and formed a complex with rat liver 10-formyltetrahydrofolate dehydrogenase.

The purpose of this research is to study of inhibitory activity of protostane type triterpens against farnesyl-protein transferase (FPTase). The ingredients of Alismatis Rhizoma, alisol B 23-acetate, C 23-acetate, alisols B and A 24-acetate, and thirteen synthetic analogues from alisol B 23-acetate exhibited inhibition activity against FPTase by scintillation proximity assay method. As a result, alisol C 23-acetate, one of the constituents of Alismatis Rhizoma, the synthetic analogues carboxylated and hydroxylated on branch chain of protostane exhibited a significant inhibitory activity. However, the compounds significantly lowered the inhibitory activity, when there is no 3 position keto on protostane skeletone.

Objectives : Effects of Rhizoma Alismatis extract on lipid composition and TBARS (thiobarbituric acid reactive substances) formation were investigated in rat fed high fat diet. Methods : Seventy male Sprague-Dawley rats were used in these experiments and housed with food and water ad libitum and Twenty rats were selected healthy over 400g body weight and fed high fat diet for 8 weeks. Rhizoma Alismatis extract was administerd at dose 100mg/kg/day, 200mg/kg/day and 300mg/kg/day p.o. for 4 weeks. Then Triglyceride, Total cholesterol, HDL-cholesterol, LDL-cholesterol, TBARS concentration and ALT(Alanine Aminotransferase), AST(aspatate transaminase) activities were determined. Results : Plasma total LDL-cholesterol showed a tendancy to decrease in all treated group(P<0.05), however plasma HDL-cholesterol, total cholesterol, triglyceride showed no significantly different. Rhizoma Alismatis extract feedings resulted in a decrease in plasma TBARS(p<0.05) concentration and AST, ALT activites but contents of TBARS in liver showed no significantly different among all the treatments. Conclusions : Reviewing these experimental results, it appears that Rhizoma Alismatis extract was effective for inhibiting lipid peroxidation and decreasing LDL-cholesterol concentration.

These studies were conducted to investigate the effects of the extracts from Hoelen alba, Alismatis Rhizoma and Atractylodes Rhizoma on the proliferation and differentiation of 3T3-L1 cells. The results were summerized as follows: Hoelen alba and Alismatis Rhizoma extracts inhibited the proliferation of preadipose 3T3-L1 cells. In inductive differentiation, all three extracts inhibited the adipose conversion in 2 days of initial-culture, Atractylodes Rhizoma extract inhibited the adipose conversion in 5 days of final-culture and Hoelen alba and Alismatis Rhizoma inhibited adipose conversion in treatment of whole term of culture. In spontaneous differentiation, Atractylodes Rhizoma extract increased the adipose conversion in 2 days of initial-culture, Hoelen alba and Alismatis Rhizoma increased the adipose conversion in 5 days of final-culture, all three extracts increased adipose conversion in treatment of whole term of culture. The 10% serum of mice treated with each sample did not affect, but the 5% serum of them inhibited the proliferation of 3T3-L1 cells. In inductive differentiation, the 10% serum of them inhibited the adipose conversion in treatment of whole term of culture.

Objectives : This study was carried out to evaluate the repeated dose oral toxicity of Alismatis Rhizoma in Sprague-Dawley(SD) rats. Methods : Male and female rats were administered orally with Alismatis Rhizoma water extract of 500 mg/kg(low dosage group), 1,000 mg/kg(middle dosage group) and 2,000 mg/kg(high dosage group). We daily observed number of deaths, clinical signs and gross findings for 14 days(twice a day). After 14 days, we measured body and organs weight. Also we analyzed hematological changes. Results : No dead SD rats and no clinical signs were found during the experiment period. Also other specific changes were not found between control and treated groups in hematology and serum biochemistry. In addition no significant changes of gross body and individual organs weight. Conclusions : These results suggest that water soluble extract of Alismatis Rhizoma has not repeated dose oral toxicity and oral LD50 value was over 2,000 mg/kg in SD rats. As a result, we can determine Alismatis Rhizoma is a relatively safe substance.

택사(Alismatis Rhizoma)는 중국에서 많이 생산되고, 우리나라에서도 그 생산량의 50%이상이 전남 순천지방에서 생산되고 있는데, 옛부터 생약으로 많이 사용되어 왔으며, 최근 택사분말은 무좀에 도포약으로 쓰이고 있어 택사에는 다양한 생리활성이 있는 것으로 생각된다. 따라서 본 연구에서는 추출용매에 따른 택사 추출물에 대한 항균 및 항산화성에 대하여 조사하였다. Paper disc법에 의한 택사 추출물의 항균 test결과 물추출물에서는 거의 모든 시험균주에서 항균활성이 나타났으나, 메탄올 및 에탄올 추출에서는 그 활성이 작게 나타났으며, 시험균주중 Vibrio parahaemolyticus균에 가장 강한 항균활성을 나타내었다. Linoleic acid에 대한 항산화력의 조사에서 택사 물추출물 100$\mu{l}$첨가시 메탄올 및 에탄올 추출물은 항균효과 나타나지 않았고, 물추출물은 효과가 나타났으나 0.1% BHT첨가시 보다는 그 효과가 적었다.

An HPLC-ESI-MS method has been developed to identify and quantify two main tetracyclic triterpenes, alisol B 23-acetate and alisol C 23-acetate in the Alismatis Rhizoma (Taeg-Sa). The relative distribution of the two triterpenes in the methanolic extract of commercially available Alismatis Rhizoma was established by selective ion monitoring (SIM) mode via electrospray ionization (ESI) source. Regression equations revealed good linear relationship, and the correlation coefficients were 0.999 and 0.998 for alisol B 23-acetate and alisol C 23-acetate, respectively, between the peak areas of the components and their concentration in a range of $0.06-2.0{\mu}g/mL$. It was found that there were significant differences in the amount of alisol B 23-acetate and alisol C 23-acetate between Korean and Chinese origins. The results showed that this method could be used to identify the two components in Alismatis Rhizoma with high sensitivity and selectivity.

The quality of Alismatis Rhizoma was evaluated by reversed-phase high performance liquid chromatographic method. Alisol B 23-acetate was used as a standard marker for evaluation. This component was fully separated from the other components in the plant extracts on a ODS column. Identifcation of alisol B 23-acetate was carried out by comparing the LC/MS spectrum of separated peak from the extract with that of standard. Alisol B 23-acetate contents in Alismatis Rhizoma obtained from several herbal markets were varied from $0. 15\%$ to $0.56\%$.

The protective and therapeutic effects of Alismatis Rhizoma extracts on rat liver injury induced by carcinogenic polycyclic hydrocarbon, benzo(a)pyrene were investigated in rats. Serum and liver triglyceride, total-cholesterol level and serum HDL-cholesterol content were measured. Alismatis Rhizoma extracts inhibited the enhanced production of lipid in chemically induced liver injury. Among 4 fractions, CHCh fraction revealed the most powerful liver-protective effect. Our results strongly suggest that Alismatis Rhizoma be a promising liver-protective agent.
