Objective: To investigate the possibility of hepatotoxicity by supplemental foods or folk herbs such as Salvia Plebeia R. Br. Methods: A hospitalized male patient with alcoholic liver disease and electrolyte imbalance had recovered, and then followed by rapid hepatic serum enzymes after taking S. Plebeia. This study monitored the clinical outcome and biochemical parameters. Result: A 58-year male had drunk frequently, which led to alcoholic steatohepatitis and hospitalization. Two weeks after his discharge from hospital, he felt nausea, dizziness, and mild difficulties in speech and walking, resulting in re-hospitalization at the Korean Medical Hospital. The symptoms disappeared on correction of the electrolyte imbalance suspected to have been caused by severe sweating while working in the outdoors, and the patient was discharged. During treatment and monitoring of his health as an outpatient, the serum hepatic enzyme rapidly elevated approximately 10-fold in hepatic enzymes; the enzyme levels fluctuated according to whether or not he was taking the boiled water of S. Plebeia. The RUCAM score was 12, which met the criteria for toxic hepatitis by S. Plebeia. His general condition and abnormal hepatic enzymes recovered with cessation of S. Plebeia and administration of Chungganplus syrup (CGX). Conclusion: This study reports the hepatotoxic risk of Salvia Plebeia, which is commonly used as a folk remedy in Korea.

Four compounds were isolated from Salvia plebeia aerial parts. Silica gel open column chromatography with a gradient elution system was used to isolate and purify these compounds. Nuclear magnetic resonance spectroscopy and mass spectroscopy were used for structural elucidation and identification, while electronic circular dichroism was used to confirm the absolute configuration. The structures were determined to be 𝛽-sitosterol (1), (-)-1S,5S,8S,10R-1-acetoxy-8-hydroxy-2-oxoeudesman-3,7(11)-dien-8,12-olide (2), ursolic acid (3), and N-methylhydroxylamine (4). Compounds 2 and 4 were isolated for the first time from this plant. Compound 2 was quantitatively analyzed via HPLC/UV. The results showed that the methanol extract of S. plebeia had a higher content of compound 2 (1.20 mg/g) than the ethanol extract (0.55 mg/g). This study could be used as a preliminary step in conducting HPLC/UV analysis of sesquiterpenoids in S. plebeia extract to assess their bioavailability and potency.

Salvia plebeia R. Br. is a plant which has been used as an edible crop and traditional medicine in Asian countries. In this study, HPLC-PDA analysis and countercurrent chromatography (CCC) coupled with reversed-phase (RP) HPLC method were applied to isolate ten isolates from 3.3 g of n-butanol soluble extract from hot-water extract of S. plebeia. The use of CCC enabled us to efficiently fractionate the starting material with less sample loss and facilitate the isolation of compounds from S. plebeia extract using RP-HPLC. The isolates were determined to be caffeic acid (1), 6-hydroxyluteolin 7-O-β-D-glucoside (2), eudebeiolide B (3), (R)-rosmarinic acid (4), homoplantaginin (5), eudebeiolide D (6), plebeiolide C (7), salpleflavone (8), eupafolin (9) and hispidulin (10) based on the spectroscopic evidence.

The comparison of $IC_{50}$ values of Salvia plebeia R. Br. extracts on L1210, $P388D_1$ cancer and Vero normal cell lines showed that the n-hexane soluble extract of S. plebeia R. Br. retains the most growth-inhibitory activity against tumor cell lines. The minimum inhibitory concentration (MIC) of the extract against microorganisms were also examined. Antimicrobial activity of amocla and ketoconazole as references was compared to those of other solvent extracts such as $H_2O$, n-hexane, chloroform, ethyl acetate and methanol. The antimicrobial activity of extract had growth inhibition activity against gramnegative bacteria, gram-positive bacteria and fungi $(MIC\;>\;200\;{\mu}g/ml)$ except for n-hexane extract. Seven bacterial strains were tested for in vitro susceptibility to the extract of S. plebeia R. Br. However the n-hexane extract of S. plebeia R. Br. inhibited the growth of several bacterial strains (MIC values between 100 and $200\;{\mu}g/ml$ for gram positive bacteria, $25\;{\mu}g/ml$ for P. putida).

The Salvia plebeia R. which is the biennial plant belonging to the Labiatae department, grows naturally in the Korea entire area. Presently, its extract (SPRE) is known to have an anti-inflammation and anti-allergy activity, but there are a few evidences about it. SPRE inhibits pro-inflammatory cytokine such as TNF-$\alpha$ and IL-6 as well as nitric oxide (NO) production in lipopolysaccharide (LPS) treated- macrophages. The co-administration of SPRE during OVA sensitization significantly reduced total IgE levels in mice. The mice who received SPRE co-administered with OVA showed a significant increase in serum OVA-specific IgG2a/b levels. Spleen-cell cultures harvested from OVA-sensitized mice showed a significant decrease in Th2 cytokine levels with a concomitant increase in Th1 cytokine levels only when SPRE co-administered with OVA. These results demonstrate that SPRE can control the LPS-induced inflammatory reaction and prevent antigen-induced Th2 immune responses in mice.

Background: Salvia has been widely cultivated for use in flavoring and folk medicines in many countries, including Korea and China. In this study, we investigated the anti-inflammatory activity and the underlying active compounds of Salvia extract and its fractions. Methods and Results: The anti-inflammatory activity was measured by assessing the inhibition of cysteinyl leukotriene production in rat basophilic leukemia (RBL)-2H3 mast cells. Salvia plebeia R. Br. was found to have the most potent inhibitory activity on leukotriene production than S. japonica and S. chanroenica had. Fifty percent ethanol extracts of S. plebeia R. Br. were successively partitioned with n-hexane, methylene chloride, ethyl acetate, 1-butanol and water. The ethyl acetate (EtOAc) fraction showed stronger anti-inflammatory activity than other solvent fractions did. The EtOAc fraction was subjected to silica gel column chromatography elution with a chloroform and methanol gradient system (100 : 1 ${\rightarrow}$ 1 : 1) yielding 10 fractions. Three kinds of fractions (chloroform:methanol = 20 : 1, 10 : 1 and 5 : 1) showed high inhibitory activity on leukotriene production. We confirmed the major compounds with anti-inflammatory activity from S. plebeia R. Br. Conclusions: In this study, the major components of S. plebeia that showed leukotriene production inhibitory activity were isolated using solvent extraction and silica gel column chromatography. Rosmarinic acid, hispidulin and luteolin were identified as the major compounds with anti-inflammatory effect.

Anthracnose of Salvia plebeia caused by Colletotrichum acutatum was observed in the exhibition field of Hamyang-gun, Gyeongsangnam-do Agricultural Research and Extension Services, in Korea. The disease mainly occurred on the leaves, petioles and stems of whole plant. The typical symptoms were water-soaked lesions on stems and petioles, rotted stems and withering then eventually died. The color of colonies of the pathogenic fungus grown on potato dextrose agar was pinkish gray. Conidia were fusiform in shape and was $8{\sim}17{\times}3{\sim}4\;{\mu}m$ in size. Appressoria were pale to dark brown in color, clavate in shape and the sizes were $8{\sim}11{\times}4{\sim}6\;{\mu}m$. Optimum temperature for mycelial growth was $25^{\circ}C$. On the basis of mycological characteristics and pathogenicity test on host plants, the fungus was identified as Colletotrichum acutatum J. H. Simmonds. This is the first report on the anthracnose of S. plebeia caused by C. acutatum in Korea.

Salvia plebeia R. Br. (Labiatae), distributed in many countries such as Korea, China, India, Iran, and Australia, is used as a folk remedy for a variety of inflammatory diseases including hepatitis, cough, diarrhea, gonorrhea, menorrhagia, tumors, and hemorrhoids. This study focused on determining the involvement of anti-inflammatory heme oxygenase-1 (HO-1) in the inhibitory activity of an extract of Salvia plebeia R. Br. leaves (SPL) on nitric oxide (NO) production and inducible nitric oxide synthase (iNOS) expression in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophages. SPL extract at the highest concentration (500 ${\mu}g/mL$) significantly inhibited NO production by approximately 85% and suppressed iNOS protein expression by approximately 90% compared to LPS-stimulated cells. The SPL extract induced the expression of HO-1 in a dose-dependent manner, and blocking HO-1 activity abolished the inhibitory effects of the SPL extract on NO production. These results suggest that an SPL extract has potent anti-inflammatory activity through HO-1 induction in RAW264.7 macrophages.

This study aimed to determinate the effect of fluorescent light and light-emitting diodes on the leaf morphology, growth and antioxidant capacity of Salvia plebeia. The plants were grown for 56 days after transplanting (DAT) under the fluorescent light (FL) and LEDs (White, Red and Blue (R+B, ratio 2:1), Blue, Red LED) under the same light intensity and photoperiod ($130{\mu}mol{\cdot}m^{-2}{\cdot}s^{-1}$, 12 hours). Leaf length, width and number of Salvia plebeia at the 56 DAT were significantly higher under the FL and red LED, and lower in the RB LED and white LED. The highest fresh and dry weights of shoot and leaf area were observed in the red LED, followed by the FL and blue LED, and the lowest in the RB LED and white LED. After 21 DAT, leaf apinasty symptom was appeared in plants grown under red LED and RB LED. The chlorophyll content was lower in the red LED. The specific leaf weight, the ratio of leaf dry weight to area, was higher in the blue LED, and lowest in the FL. No significant difference in DPPH radical scavenging activity of Salvia plebeia under the different light sources. All the integrated results suggest that the FL light is a proper light conditions for a closed cultivation of Salvia plebeia.

Background: Small particles increase airway inflammation upon reaching the alveoli. Here, we investigated the protective or therapeutic effects of Salvia plebeia R. Br. (SP_R) extracts on airway inflammation. Methods and Results: To investigate the anti-inflammatory activity of SP_R extracts, we measured their inhibitory effect on the production of reactive oxygen species (ROS) expression of inflammatory mediators, and immune cell infiltration in MH-S alveolar macrophage cells and in the ambient particulate matter (APM)-exposed airway inflammation mice model. The SP_R extracts inhibited the production of ROS and expression of IL-4, IL-10, IL-15, and IL-17A mRNA in APM-stimulated MH-S cells. Oral administration of SP_R extracts suppressed APM-induced inflammatory symptoms, such as high alveolar wall thickness, excess collagen fibers, decreased mRNA expression of chemokines (Ccr9, Ccl5, Ccr3), inflammatory cytokines (IL-15, TNF-${\alpha}$), and IL-4 Th2 cytokine in the lung. The SP_R extracts also inhibited ROS production, granulocyte ($CD11b^+Gr-1^+$) infiltration, IL-17A, TNF-${\alpha}$, macrophage inflammatory protein (Mip-2), and chemokine (C-X-C motif) ligand 1 (Cxcl-1) production in the airway. The specific compounds in the SR-R extracts that mediate the anti-inflammatory effects were identified. Conclusions: In this study, SP_R extracts effectively inhibited airway inflammatory responses, such as ROS production and granulocyte infiltration into the airway, by regulating the expression of chemokines and inflammatory cytokines.
