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.

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.

Traditionally, the root of Lithospermum erythrorhizon Sieb. et Zucc(L.E) has been used as efficacious therapy for inflammation, burns, frostbite and skin ailments (e.g eczema and psoriasis). It contains isohexenylnaphthoquinone derivatives (shikonin and its esters) and furylhydroquinones (shikonofurans) in lipophilic fractions and caffeic acid oligomers (rosmarinic acid, lithospermic acid B) in polar fractions. Recently, new preparative isolation and analysis procedures of shikonin along with its oligomers from the extract of L. erythrorhizon by the combination of high-speed counter-current chromatography with high-performance liquid chromatography-diode array detection have also been introduced. Although there have been many reports on the wound healing, antiinflammatory, and anticancer effects, the research on the effects of anti-atopic dermatitis of the root of L. erythrorhizon were relatively scarce. However, in recent years, new information gathered from research efforts, on the anti-atopic dermatitis properties of the extract or constituents of L. erythrorhizon has been accumulated. In this paper, the findings and advance on the in vitro and in vivo activities of L. erythrorhizon and its constituents especially focused on antiinflammatory and anti-atopic dermatitis effects are summarized. The phytochemical constituents of L. erythrorhizon or its tissue cultures are also presented. Although there are few to verify or refute its activity in human, one result of clinical study of the extract of L. erythrorhizon on the atopic dermatitis patients was introduced to assess the possibility of its clinical use. The reported mechanisms of action and in vivo pharmacological studies in different animal models for the various types of extracts or constituents of L. erythrorhizon are supportive of its therapeutic potential or dietary supplement, however, more evidence from clinically relevant models, as well as systemic studies on the active constituents or the various types of standardized extracts at the cellular and molecular level, are required.

Cadmium ($Cd^{2+}$) is a heavy metal and a potent carcinogen implicated in tumor development through occupational and environmental exposure. However, the auditory effect of $Cd^{2+}$ is not poorly understood. The purpose of the present study was to investigate whether prevent the ototoxic effects of $Cd^{2+}$ by antioxidnat in auditory cell line, HEI-OC1. Rosmarinic acid is a naturally occurring phenolic compound and also known to possess marked antioxidant properties. We showed that antioxidnat inhibited the the cytochrome c release induced by $Cd^{2+}$. In addition, we showed that the regulatory effect of antioxidnat on apoptosis is through the caspase-9 activation, and extracellular signal-regulated kinase activation in auditory cells. These results suggested antioxidnat its therapeutic usefulness, against $Cd^{2+}$ induced activation of caspase-9 and ERK.
