This study has been conducted to establish the optimal extraction process and HPLC analysis method for the determination of marker compounds as a part of the materials standardization for the development of health functional food materials from Astragali radix. Five extraction conditions including the shaking extraction at room temperature and the reflux extraction at $85^{\circ}C$ with 30%, 50% and 95% ethanol were evaluated. Reflux extraction with 50% ethanol showed the highest extraction yield as $27.27{\pm}2.27%$, while the extraction under reflux with 95% ethanol showed significantly the lowest yield of $10.55{\pm}0.24%$. The quantitative determination methods of calycosin-7-O-${\beta}$-D-glucoside and calycosin as marker compounds of Astragali radix extracts were optimized by HPLC analysis using a Thermo Hypersil column ($4.6{\times}250mm$, $5{\mu}m$) with the gradient elution of water and acetonitrile as the mobile phase at the flow rate of $0.8mLmin^{-1}$ and a detection wavelength of 230nm. The HPLC/UV method was applied successfully to the quantification of two marker compounds in Astragali radix extracts after validation of the method with the linearity, accuracy and precision. The contents of calycosin-7-O-${\beta}$-D-glucoside and calycosin in 50% ethanol extracts by reflux extraction were significantly higher as $1,700.3{\pm}30.4$ and $443.6{\pm}8.4{\mu}g-1$, respectively, comparing with those in other extracts. The results indicate that the reflux extraction with 50% ethanol at $85^{\circ}C$ is optimal for the extraction of Astragali radix, and the established HPLC method are very useful for the evaluation of marker compounds in Astragali radix extracts to develop the health functional material from Astragali radix.

Objectives : In present study, we investigated a therapeutic effect of Astragali Radix on hypothyroidism rat model induced by 6-Propyl-2-thiouracil (PTU). Methods : Six-week-old male Sprague-Dawley rats were divided into five groups : Group one included the normal mice. Group two was administrated PTU. Group three and four were administrated the aqueous extract of Astragali Radix 150 and 300 mg/kg before start of PTU treatment. Group five (Positive control) was administrated with levothyroxine 0.5 mg/kg. During this moment the body weight, liver $H_2O_2$ and catalase (CAT) amount, serum thyroid hormone, serum asparte aminotransferase (AST) and alanine aminotransferase (ALT), gland weights were measured with histopathological changes of thyroid glands. These results were compared with levothyroxine 0.5 mg/kg treated rats. Results : The PTU treatment lead to marked decreases of body weight, level of thyroid hormone in serum and liver CAT activation. Also, PTU treatment increased thyroid gland weight, thyroid gland hormone TSH, liver $H_2O_2$ amount and level of AST in serum. On the other hands, the administration of Astragali Radix extract increased body weight gains and ameliorated histopathological changes of thyroid such as hyperplasia of follicular cells with of follicular colloid contents and sizes. In addition, the administration of Astragali Radix extract increased level of $T_4$ in serum, CAT activation in liver. Moreover, the administration of Astragali Radix extract decreased levels of TSH and AST in serum and $H_2O_2$ amount in liver Conclusions : This study suggests that Astragali Radix extract has therapeutic effects on hypothyroidism via promoting thyroid hormone production.

The effects of herbal medicine on travecular bone area were studied using ovariectomized rat as an animal model of Type I osteoporosis and SAM P6 as that of Type II. We counted red blood cells(RBC), hemoglobin(Hb), and hematocrit(Hct) using Couter`sR method. Each traditional boiling water extract of Achyrathis Radix, Psoraleae Fructus, Rehmanniae Radix Preparat, and Cornii Fructus and a systemic water extract of Astragali Ractiex was given 5g/kg/day, p.o., for 30 days in a group of 4-5 ovariectormized rats. One ml of blood was taken by tail vein at day 0, 7, 14, 21, and 30 days after administration of the extract. The traditional hot water extract of Cervi parvumn Corni (Cervi) was given the same dose as described above for 14 days in a group of 10 SAM P6 mice and systemic water extract of Astragali Radix was administered as the same dose as above for 30 days in 10 SAM P6 mice. Travecular bone area was measured 5 mcm decalcified and stained thin bone slice by image analysis using a digitalizer. In Type I, ovariectomized rats, administration of Astragali Radix, Rhemanniae Radix Preparat, and Corni Fructus decreased in RBC, Hb and Hct. In Type II, administration of Cervi increased in RBC and Hct and that of Astragali Radix was also elevated RBC. In Type I, any administration of herbal medicine used in this study did not elevate travecular bone area significantly except Corni Fructus showed a trend of increase in travecular bone area. However, Type II, Cervi and Astragali Radix increased in both mean and total travecular bone area. Thus, there are significant difference in response of herbal medicine in different types of osteoporosis.

This study aimed to evaluate the effects of Astragali radix on brain edema of intracerebral hemorrhage(ICH)-induced rats. Brain edema following ICH was induced via the stereotaxic intrastriatal injection of bacterial collagenase type VII in Sprague-Dawley rats. Ethanol extract of Astragli radix was treated once a day for 3 days. Then brain hematoma volume and edema were examined. Immunohistochemistry was processed for iNOS, c-Fos, Bax, and HSP72 expressions in the brain sections and each immuno-labeling were calculated with image analysis. Ethanol extract of Astragli radix reduced hematoma volume(not significantly) and brain edema(significantly) ICH induced rats. Ethanol extract of Astragli radix reduced iNOS expressions, c-Fos, Bax and HSP72 positive cells significantly and reduced apoptotic bodies and swollen neurons in ICH induced rat brain. These results suggest that Astragli radix plays an inhibitory role in the hemorrhagic, inflammatory and apoptotic events induced by ICH. And it is supposed that neuroprotective effect of Astragli radix reveals by anti-apoptosis mechanism.

Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.
