가든 세이지 추출물의 추출 최적 조건을 알아보고자 각각 추출 용매별, 농도별, 시간별로 비교하였다. 가든 세이지는 60% ethane에서 24시간 추출하는 것이 최적 추출조건으로 가장 효율적이라 판단되었다. 한편 생리활성 효과는 추출물의 phenol 농도를 $200\;{\mu}g/ml$로 조절하여 실험하였다. DPPH에 대한 전자 공여능은 60% ethanol 추출물에서 64.4%로 나타났으며, ABTS radical decolorlization은 60% ethanol 추출물에서 96.9%, antioxidant protection factor는 60% ethanol 추출물에서 2.30PF로 나타났으며, PF와 같이 지용성 물질의 항산화력을 나타내는 TBARS값은 centrol의 $0.62{\times}10^2\;{\mu}M$에 비해 60% ethanol 추출물에서 $0.28{\times}10^2\;{\mu}M$의 낮은 TBARS값을 나타내어 항산화 효과가 우수한 것으로 나타났다. Xanthine oxidase 활성억제 효과는 100의 저해율을 나타냈고, ACE활성억제 효과는 75.5%의 저해율을 나타내었으며, Helicobacter pylori균에 대한 활성도 $200\;{\mu}g/ml$ 농도의 액체배지에서 63.4의 저해율을 나타내어 생리활성효과도 우수한 것으로 나타났다.

This study was conducted to investigate the effect of simulated acid solution(SAS) on acid buffering capacity, chlorophyll content and butrient leacking in 4 herb species(Petunia hybrida Vilm, Gomphrena globosa L. Celosia cristat L. Salvia officinallis L) . The acid buffering capacity in the leves was increased in the treatment of pH 3.0 in Celosia L., whereas it was increased at pH 4.0 in Petunia Petunia hybrida Vilm. and Gomprean globosa L.. But, the acid buffering capacity of the leaves did not work at ph 2.0 treatment in 4 herb species. With decreasing pH level, the chlorophyll content of Petunia hybrida Vilm. and Gomphrena globosa L. Was markedly decreased than that of Gelosia cristata L. and Savia officinalis L. As the pH levels decreased from 5.6 to 2.0 the nutrient leaching from leaves was significantly increased in 4 herb species. In pH 4.0 and 5.6, the concentrations of nutrient leaching from leaves were higher in Perunia hybrida Vilm. and Gomphrean globosa L. than Gelosia cristata L. and Salvia officinalis L., Based on the results, there was a great differences in response to SAS among the 4 herb species. Im general, Gelosia cristata L. and Salvia officinalis L. represented a higher tolerance to SAS Petunia hybrida Vilm, and Gomphrena globosa L..

Primary pro-inflammatory cytokines are a trio: tumor necrosis- $\alpha$ (TNF-$\alpha$), interleukine-$\beta$ (IL-$\beta$), and interleukine-6 (IL-6). These cytokines initiate and regulate the acute-phase inflammatory response during infection, trauma, or stress and appear to play an important role in the immune process. Nitric oxide (NO) is a multi-functional mediator, which plays an important role in regulating various biological functions in vivo. NO production by inducible nitric oxide synthase (iNOS) in macrophages is essential for the defense mechanisms against microorganisms and tumor cells. However, over-expression of iNOS by various stimuli, resulting in over-production of NO, contributes to the pathogenesis of septic shock and some inflammatory and auto-immune disease. Solvent fractions of sage ( Salvia officinalis L.), which is cultivated in Jeju-Do, was assayed for their effects on TNF-$\alpha$ and IL-6 production in LPS-stimulated RAW 264.7 macrophages. Hexane and ethylacetate (EtOAc) fraction of sage inhibited the protein and mRNA expression of TNF-$\alpha$ and IL-6 in LPS stimulated RAW 264.7 cells at the concentration of 100 $\mu\textrm{g}$/$m\ell$. Also, incubation of RAW 264.7 cells with the fraction of hexane or EtOAc (50 $\mu\textrm{g}$/$m\ell$) inhibited the LPS induced nitrite accumulation and the LPS/IFN-${\gamma}$ induced iNOS protein. And this inhibition of iNOS protein is concordant with the inhibition of iNOS mRNA expression. Above results suggest that extract of sage may have anti-inflammatory activity through the inhibition of pro-inflammatory cytokines (TNF-$\alpha$, IL-1$\beta$, IL-6), iNOS and NO.

The antidepressant drug trazodone (TRZ) is commonly used for treating depression, anxiety, and insomnia, however, it causes cardiotoxicity, which is one of its limitations. The objective of this work was to investigate the impact of sage (Salvia officinalis) in rats against cardiotoxicity induced by TRZ and to investigate the mechanisms involved in its cardio-protective properties through autophagy and oxidative stress. Fifty male albino rats were split randomly into five experimental groups: control group, sage oil group (100 mg/kg), TRZ group (20 mg/kg), protective group, and curative group. Cardiac function biomarkers (aspartate aminotransferase [AST], creatine kinase-MB [CK-MB], and cardiac troponin T [cTnI]) were assessed in serum. Oxidative stress and inflammatory biomarkers in cardiac tissue (total antioxidant capacity, malondialdehyde, and tumor necrosis factor-α) were evaluated. Heart tissues were subjected to histological, immunohistochemical, and ultrastructural evaluations. DNA damage also evaluated. Significant rise in the levels of AST, CK-MB, and cTnI were observed with enhanced autophagy along with marked histopathological changes in the form of interrupted muscle fibers with wide interstitial spaces with areas of hemorrhage and extravasated blood and interstitial mononuclear cellular infiltration in TRZ group. DNA damage was also significantly increased in TRZ group. However, administration of sage in both protective and curative groups show marked improvement of the cardiac alterations. In conclusion, sage ameliorated the alterations in the heart induced by trazadone through modulation of autophagy and oxidative stress.

Objective: Diabetes mellitus (DM) is the most common metabolic disorder that defined by chronic hyperglycemia for the deficiency in insulin secretion or resistance. Hyperglycemia could induce non-enzymatic glycation of proteins. It has been suggested that some traditional plants can improve blood glucose and inhibit glycation process. This work evaluates and compares the anti-glycation activities of four Iranian plant extracts in vitro. Methods: The methanolic extract of "Fumaria officinalis, Stachys lavandulifolia, Salvia hydrangea and Rosa Damascene" was prepared in three different concentrations. Phenolic, flavonoids content and antioxidant activity were evaluated. The multistage glycation markers- fructosamines (early stage), protein carbonyls (intermediate stage) and ${\beta}$ aggregation of albumin were investigated in the bovine serum albumin (BSA)/ glucose systemt. Results: All plants showed the high potency of scavenging free radicals and glycation inhibition in the following order: Fumaria officinalis> Rosa Damascene> Stachys lavandulifolia > Salvia hydrangea. There was a significant correlation between antioxidant and anti-glycation activity. Also, the antioxidant and anti-glycation capacity of extracts correlated with total phenolic and flavonoids content. Conclusion: Our findings demonstrated that the studied plants are good sources of anti-glycation and antioxidant compounds and, these properties can primarily attributable to phenolics, particularly flavonoids.

The present work evaluated the effects of alcoholic extracts of salvia (Salvia officinalis), thyme (Thymus vulgaris), and 2 pure compounds (thymol and menthol) on the viability of Echinococcus granulosus protoscolices in vitro. Four different concentrations of each extract (2,500, 1,500, 1,000, and 500 ${\mu}g$/ml) and 3 different concentrations each of thymol and menthol (50, 10, and 1 ${\mu}g$/ml) were used. Concentration of 2500 ${\mu}g$/ml of both extracts showed a significant protoscolicidal activity on the 6th day. Complete loss of viability of protoscolices occurred with 500 ${\mu}g$/ml concentration of both extracts at day 6 and day 7 post-treatment (PT), respectively. Pure compounds, i.e., menthol and thymol, showed potent effects with 50 ${\mu}g$/ml concentration at day 2 and day 5 PT, respectively. These effects were compared with those of albendazole sulfoxide (800 ${\mu}g$/ml), a commonly used treatment drug for hydatidosis. Krebs-Ringer solution and the hydatid cystic fluid at a ratio of 4:1 was a good preservative solution which kept the protoscolices viable for 15 days.
