RESUMEN
OBJECTIVE: To study the chemical constituents from the stems of Acorus tatarinowii Schott. METHODS: The chemical constituents were isolated from the 70% ethanol-soluble extract of the stems of Acorus tatarinowii Schott and purified by a series of column chromatography methods, including MCI, silica gel, Sephadex LH - 20, HPLC and so on, and their structures were identified by physical chemical constants and NMR techniques. RESULTS: A total of twelve compounds were isolated and identified as (7S, 8R) -4, 9'-dihydroxyl-3, 3'-dimethoxyl-7, 8-dihydrobenzofuran-1'-propylneolignan (1), (-) -lyoniresinol (2), dihydrocubebin (3), evofolin B(4), (+) -icariol A2 (5), β-sitosterol(6), (+) -13-hydroxyspathulenol(7), aromadendrane-4β, 10β-diol(8), anomallenodiol( 9), (9CI) -cis-4-(3, 4-dihydroxy-2, 6, 6-trimethyl-1-cyclohexen-1-yl) -2-butanone (10), (3E) -rel-4-[(3R, 4S) -3, 4-dihydroxy- 2, 6, 6 -trimethyl-1-cyclohexen-1-yl]-3-buten-2-one(11), and ixerol B(12), respectively.

RESUMEN
Objective: To analyze the effect of extrusion factors such as extrusion speed, screen hole diameter, and extrusion times on the texture properties of extrudate and the quality of pellets. Methods: In this study, microcrystalline cellulose (MCC) as pelletization aid, lactose, Methocel E5 HPMC, Methocel E15 HPMC, Methocel K100 HPMC, and eight kinds of herbal extracts (extracts of Areca catechu, Patrinia scabiosae folia, Acorus tatarinowii, Sargentodoxa cuneata, Psoralea corylifolia, Dachuanxiong Decoction, Ligusticum chuanxiong, and Gastrodia elata) were used as model drugs. Extrudates were prepared under different levels of process parameters, and one part was used to measure the texture parameters, the other part used for quality evaluation after spheronization. Results: With a large screen hole diameter, it showed that hardness of extrudate became lower and the adhesiveness as well as the springiness was significantly higher, leading to a large particle size and poor roundness of pellets. Repeated extrusion could increase hardness, cohesiveness, chewiness, and resilience of extrudate. Not any strong correlation was found between the extrusion speed and texture properties in the study. Conclusion: The extrusion process could be purposefully selected to prepare ideal pellets accroding to texture properties of extrudate.
RESUMEN
Objective To study antidepressant effect and mechanism of different polar fraction of Acorus tatarinowii Schott.on depression mouse model and explore the mechanism. Methods Different polar fractions were prepared by systematic solvent method. The adult dose recommended by Chinese Pharmacopeia ( 10 g?d-1 ) was converted to the dose of mouse. Intragastric administration was performed.A total of 80 male mice was randomly divided into normal control group,model control group and different polar fraction groups of Acorus tatarinowii Schott.. Depression mouse model was established by chronic unpredictable mild stimulation ( CUMS) with solitary feeding,and external performance of mice of different groups was observed. After 21-day feeding,blood was harvested from eyes of the mice.Concentrations of triiodothyronine (T3),tetraiodothyronine (T4), thyroid-stimulating hormone ( TSH) ,adrenocorticotrophic hormone ( ACTH) in mouse plasma and 5-hydroxy tryptamine ( 5-HT) , ACTH in brain were measured by ELISA method. Results Concentrations of T3 , T4 and ACTH in model control group [(1.203±0.042),(44.80±2.21),(11.27±0.50) ng?mL-1] were significantly increased as compared with the normal control group [(0.794±0.028),(24.87±1.25),(7.04±0.24) ng?mL-1] (P<0.05).Concentration of 5-HT in brain (146.87±10.96) was significantly decreased as compared with that of normal group ( 237. 11 ± 21. 87 ) ng?L-1 , and concentration of ACTH (58.94±4.46) ng?L-1 was significantly increased as compared with that of normal group [(38.89±2.26) ng?L-1,P<0.05)]. Concentrations of T3[(0.824±0.067),(0.812±0.051),(0.943±0.049) ng?mL-1],T4[(25.97±1.96),(27.53±1.88), (31.26±1.97) ng?mL-1] and ACTH [(7.21±0.40),(7.58±0.39),(8.69±0.42) ng?mL-1] in extraction group,cyclohexane group and chloroform group were significantly decreased as compared with model control group. At the recommendation dose of Chinese Pharmacopeia,concentrations of 5-HT in brain [(219.59±10.48),(202.19±11.95),(186.96±10.29) ng?L-1] were significantly increased,and concentrations of ACTH [(41.65±2.65),(44.87±2.95),(47.75±3.06) ng?L-1] were decreased ( P<0.05) . Conclusion Mouse model of CUMS shows typical depression symptom,and the symptom has relationship with the concentrations of endocrine hormones of T3 , T4 , ACTH, 5-HT, etc. Extraction and low polar fractions ( cyclohexane, and chloroform) of Acorus tatarinowii Schott. can partly correct incretion disorder of depression model, which may be parts of the reasons why Acorus tatarinowii Schott.exerts anti-depressant effect.
