  • The effect of aqueous extract of Lycopus lucidus Turcz. (Labiatae)(LLAE) on mast cell-mediated immediate-type allergic reactions was investigated. LLAE (0.01 to 1 mg/g) dose-dependently inhibited systemic anaphylaxis induced by compound 48/80. LLAE (0.001 to 1 mg/g) also dose-dependently inhibited local anaphylaxis activated by anti-dinitrophenyl (DNP) IgE. When LLAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. LLAE (0.001 to 1 mg/mι) dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when LLAE (1 mg/mι) was added, significantly was increased, compared with that of normal control. These results provide evidences that LLAE may be beneficial in the treatment of allergic diseases.

  • The rhizomes of Salvia miltiorrhiza Bunge(Labiatae) has been used in Chinese traditional medicine for the treatment of coronary heart diseases and myocardial infarction. As a part of a research for standardization of crude oriental drugs, we have determined the content of tanshinone IIA in Salvia miltiorrhiza purchased from various regions of Korea. The HPLC method by which quantitative analysis was conducted, showed reproducible results and chromatographic isolation of tanshinone IIA was accomplished successively.

  • Salvia bucharica belonging to the family Lamiaceae (Labiatae), afforded a novel terpenoid (1) named as salvatrione. The structure of 1 was elucidated through extensive 2-D NMR experiments and the biogenetic pathway of 1 has also been proposed. On biogenetic grounds, 1 may be considered to be a pseudo-triterpenoid as it is derived from the coupling of mono/ diterpenic units and not from squalene.

  • Rosmarinic acid and its methyl ester, isolated from the ethyl acetate soluble fraction of the methanolic extract of Salvia miltiorrhiza Bunge (Labiatae), were found to inhibit the oxidation of L-tyrosine catalyzed by mushroom tyrosinase with the $IC_{50}$ values of 16.8 and $21.5\;{\mu}M$, respectively. It was comparable with kojic acid, a well-known tyrosinase inhibitor, with an $IC_{50}$ of $22.4\;{\mu}M$. The inhibitory kinetics analyzed by the Lineweaver-Burk plots, were found rosmarinic acid and its methyl ester to be competitive inhibitors with $K_i\;of\;2.4{\times}10^{-5}\;and\;1.5{\times}10^{-5}\;M$, respectively.

  • The effect of aqueous extract of Isodon japonicus Hara (Labiatae) (IJAE) on mast cell-mediated immediate-type allergic reactions was investigated. IJAE inhibited compound 48/80-induced systemic anaphylaxis and immunoglobulin E (IgE)-mediated local anaphylaxis. When IJAE was pretreated at the same concentration with systemic anaphylaxis, serum histamine levels were reduced in a dose-dependent manner. IJAE dose-dependently inhibited histamine release from rat peritoneal mast cells (RPMC) activated by compound 48/80. The level of cAMP in human mast cell line (HMC-1) cells, when IJAE was added, significantly was increased, compared with that of normal control. These results indicate that IJAE will beneficial in the treatment of immediate-type allergic reaction.

  • For the quality control of Leonuri Herba, alkaloid compound, leonurine, was isolated from the MeOH extract of Leonurus sibiricus L. (Labiatae) and identified by the spectroscopic analysis. A quantitative analysis of leonurine using HPLC method showed that the average contents were $0.124{\pm}0.065%$ in 34 samples collected throughout the regions of Korea.

  • The essential oils of Lycopus lucidus have been studied. The essential oil obtained from the dried herba by steam distillation followed by fractionation by column chromatography was analysed by gas chromatography-mass spectrometry(GC-MS). The compounds identified by GC-MS were carvacrol, 2,5-dimethoxy-p-cymene, trans-caryophyllene, spathurenol and $trans-{\beta}-farnesene$. Two compounds, thymol and caryophyllene were isolated by silica gel column chromatography and analyzed by TLC, IR, Mass and NMR. And the weak diuretic effects of essential oil and water extract from the dried drugs were observed in rats.
