(no cell survived) A double dilution of the fraction(10ug/ml) still showed strong activity.(0.2 cells survived) The ether fraction contained strong activity. Of the fraction which have veen obtained by a prcparative silicagel TLC I, II, III & IV were cytotoxic, but V and VI were inactive Howevcr, it is worthwhile to note that no one of these has no strong Cytotoxicity as the pertoleum ether fraction itself. This observation says that the active fractions could be additive or synergic to each other. The most active fraction, IV, was scrached out from the TLC and its UV-spectrum taken. The absorption maxima were 207 and 272 nm, indicating the presence of a flavanone strucuture.

  • Rosmarinic acid (1) and methyl rosmarinic acid (2), isolated from the ethyl acetate soluble fraction of the methanolic extract of Salvia miltiorrhiza Bunge (Lamiaceae) were found to be the tyrosinase inhibitors and scavengers of 1, 1-diphenyl-2-picrylhydrzyl (DPPH) radical. Compounds 1 and 2 inhibited the oxidation of L-tyrosine catalyzed by mushroom tyrosinase with $IC_{50}$/ of 16.8 $\mu\textrm{M}$ and 21.5 $\mu\textrm{M}$. respectively. It compared well with kojic acid. a well-known tyrosinase inhibitor. with an $IC_{50}$ of 22.4 $\mu\textrm{M}$. The inhibitory kinetics, analyzed by a Lineweaver-Burk plot, found rosmarinic acid and its methyl ester to be competitive inhibitors with $K_{i}$ of $2.35{\times}10^{-5}M$ and $1.52{\times}10^{-5}M$ respectively. In addition, compounds 1 and 2 showed the scavenging activities on DPPH radical, with $IC_{50}$ of 4.27 $\mu\textrm{M}$ and 3.05 $\mu\textrm{M}$. respectively. These scavenging effects were more potent than that of L-ascorbic acid ($IC_{50}$ = 11.75$\mu\textrm{M}$).

  • Objects : The purpose of this study was to observe the effect of Salviae Miltriorrhiza Radix(SMR) water-extract on intracerebral hemorrhage(ICH) and neuronal apoptosis in the injured areas. Method : ICH was induced by the stereotaxic intrastriatal injection of bacterial collagenase type IV in Sprague-Dawley rats. The rats were givened oral SMR treatment once a day for three days after the ICH treatment. TUNEL positive cells in the affected regions were performed by TUNEL assay, Bax and Bcl-2 positive cells by immunohistochemistry and the Bax expression by western blotting method. Results : The results are as follow; 1. SMR significantly reduced the number of TUNEL positive cells in the peri-hematoma reigions of ICH-induced rats. 2. SMR significantly reduced the number of Bax positive cells in the peri-hematoma regions of ICH-induced rats. 3. SMR did not affect the number of Bcl-2 positive cells in the peri-hematoma regions of ICH-induced rats. 4. SMR significantly reduced the Bax expressions compared with ICH group in hemorrhagic hemisphere of ICH-induced rats. Conclusion : These results suggest that SMR is effective in reducing neuronal apoptosis.

  • The purpose of this study was to pelletize to calendula and salvia seeds with peat moss as basic material for the efficient greening and vegetating of slopes and damaged areas. Also the pelletizing was compressed by spherical types that mixed basic fertilizer of N.;300 mg/l, P.;200 mg/l, K.;400 mg/g and plant growth regulator of A and NAA each 300PPM. Soil and soil surface seeding methods were researched to find the growing state of germination percent, germination date, germination force, length of leaf, number of leaf, width of leaf, length of plant, and etc. Comparing with controlled pelletizing, peat moss and +GA pelletizing treatments resulted in higher from two to three times as following growing states : length of leaves, number of leaves, width of leaves, length of plants, length of roots, fresh weights, and ratio of germination. Especially the two treatments above showed four more times effects than the +NNA treatment. Also their germinating date germinating force were earlier and stronger. The surface seeding method was superior to soil seeding.

  • Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that regulates various cellular processes such as cell survival, angiogenesis and proliferation. In the present study, we examined that Cryptotanshione(CT), a tanshinone from oriental traditional medicinal herb Danshen (Salvia miltiorrhiza Bunge), had the inhibitory effects on hypoxia-mediated activation of STAT3 in androgen independent human prostate cancer PC-3 cells. CT inhibited the protein expression of hypoxia-inducible factor-1alpha (HIF-$1{\alpha}$) under hypoxic condition. Consistently, CT blocked hypoxia-induced phosphorylation and nuclear accumulation of STAT3. In addition, CT reduced cellular of vascular endothelial growth factor (VEGF), a critical angiogenic factor and a target gene of STAT3 induced under hypoxia. Of note, chromatin immunoprecipitation (ChiP) assay revealed that CT inhibited binding of STAT3 to VEGF promoter. Taken together, our results suggest that CT has anti-angiogenic activity by disturbing the binding STAT3 to the VEGF promoter in PC-3 cells.

  • Dansam, the root of Salvia miltiorrhiza Bge, (Labiatae), has a bitter taste and a slightly 'cold' property, and is nontoxic. In the present study, effect of Dansam on nitric oxide (NO) generation from peritoneal macrophags was examined. Dansam had no effect on NO generation by itself, whereas recombinant interferon-${\gamma}\;(rIFN-{\gamma})$ alone had modest activity. When Dansam was used in combination with $rIFN-{\gamma}$, there was a marked cooperative induction of NO generation in a dose-dependent manner, The optimal effect of Dansam on NO generation was shown at 6 hr after treatment with $rIFN-{\gamma}$. Furthermore, the effect of Dansam was mainly dependent on Dansam-induced tumor necrosis $factor-{\alpha}\;(TNF-{\alpha})$ secretion. These results suggest that Dansam induces NO generation from macrophages by the result of Dansam-induced $TNF-{\alpha}$ secretion.

  • In this study, the marker compound contents of both the taproot and lateral root of Danshen (Salvia miltiorrhiza Radix), which is cultivated in Korea, were investigated. The salvianolic acid B content was the highest in the taproot (5.17-6.75%) and lateral root (3.99-5.69%). The cryptotanshinone, tanshinone I, and tanshinone IIA contents were higher in the lateral root than in the taproot of Danshen (p <0.05). Principal component analysis results revealed that the taproot was correlated to the salvianic acid A, rosmarinic acid, salvianolic acid B, and salvianolic acid A contents, whereas the lateral root was correlated to the cryptotanshinone, tanshinone I, and tanshinone IIA contents. The total phenolic content and total flavonoid content of the taproot were higher than those of the lateral root (p <0.05); however, the antioxidant activities of the taproot and lateral root of Danshen were similar. The salvianolic acid B content was correlated to the TPC of the taproot (r=0.748) and the 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging activity of the lateral root (r=0.847). This study could provide useful information for the classification of Danshen as a herbal medicinal product.

  • 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.

  • Farmesy-Protein Transferase의 저해제는 Ras단백질의 발암활성을 차잔하는 항암제의 후보로서 알려져있다. 우리는 최근에 topoisomerase I에 대하여 저해활성을 갖는 dihydrotanshinone I을 약용식물인 Salvia miltorhiza Bunge(Danshen)으로부터 분리하였다. Dihydrotanshinone Iml 작용기작의 해석을 위한 시도에서 farmesy-Protein Transferase에 대한 저해능($IC_{50}$치= 15ug/ml)을 관찰하였으며, 이것은 유용한 항암제로서의 가능성을 제시한 결과로 본다.
