Ursolic acid was isolated from Prunellae Herba (Prunella vulgaris var. lilacina) and identified by direct comparison with an authentic sample. A method of analysis for the evaluation of ursolic acid was developed based on extraction of ground plant material, followed by quantitative determination using capillary gas chromatography of the TMS derivative. Quantitative analysis by GC after derivatisation under mild silylating conditions showed 0.31% ursolic acid in 20 samples collected throughout regions of Korea while no ursolic acid was detected in the samples of the whole plant of Thesium chinense, a substitute for Prunellae Herba in southern regions of Korean peninsula.

It was claimed that the herbal medicine with the function of strengthening the body resistance exerts to enhance the immunity. And the medicine with the effect of eliminating the pathogenic factor is stated to inhibit the immune response. To evaluate the the effects of the herbal medicine on the immune response, the mice were administrated with the herbal medicine for 2 weeks. And the responses were analyzed. As the result, water extract of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Semen Coicis, Herba Ecliptae, Spica Prunellae, and Radix Sophorae increased the ROI production, while Radix Tripterygia inhibited it. Phagocytic activity was increased after administration of Radix Astragal, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Radix Sophorae. NK cell activity was also significantly inhibited by Radix Tripterygia. Administration of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Semen Coicis enhanced the antibodies(hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen, while Radix Sophorae and Radix Tripterygia decreased it. Radix Sophorae and Radix Tripterygia also decreased the allogenic immune response and mixed-lymphocyte reaction. And all the experimental herbs decreased contact hypersensitivity against dinitroflurobenzene. These results show Radix Astragali, Fructus Psoraleae, Spica Prunellae, Cortex Acanthopanacis, Semen Coicis and Herba Ecliptae enhanced innate immunity, humoral and cellular immune responses. However Radix Sophorae and Radix Tripterygia exert imunosuppressive action. Also these results indicate that the medicine with the action of the strengthening the body resistance enhances the immunity. And the the some of drugs belonging to the eliminating the pathogenic factor also increase the immune responses.

This study is an attempt to investigate the effects of the water extracts of the whole plants of Prunella vulgaris (Labiatae) and Thesii chinense (Santalaceae) on the acute toxicity, the activities on central nervous system and the diuretic action. The acute toxicities shown by $LD_{50}$ were estimated to be more than 3000 mg/kg p.o. and 1,000 mg/kg s.c. in the extracts of Prunellae Herba and Thesii Herba, respectively, in mice. The extracts at a dose of 2,000 mg/kg p.o. did not show any activities on central nervous system, i.e, sedative, analgesic, hypothermic and anticonvulsant actions. The urination in rats was increased by 45.5% and 57.6% when 100mg/kg of each of the extracts were given orally. The results obtained revealed that the water extracts possessed weak diuretic actions without any of central nervous system activities. Furthermore, it is considered that the potassium in the extract may play a role in the diuretic action.

Objectives : Categorized as 'cheongyeol' herbs, Herba Prunellae, Flos Lonicerae and Radix Scutellaria have been proven to have effect on degenerative brain disease, cerebrovascular disease and brain tumor because of their anti inflammation, antioxidant, or anticancer effects. In this study, we studied activity against reactive oxygen species and anti inflammation effect of these three 'Cheongyeol' herbs. Methods : We measured each herb's yield of ethanol extracts, phenolic contents and activities against DPPH, hydroxyl radical and superoxide anion. Also through 6-hydroxydopamine (6-OHDA) induced oxidative damage in SH-SY5Y human neuroblastoma cell line, we measured antioxidant effect and NO activity of the three herbs. From the three herbs, we chose Prunella Herba, which showed the highest antioxidant effect, and studied its cell survival rate and anti inflammation effect through COX-2 and iNOS. Results : All three herbs showed significant results, and especially Prunella Herba showed significant effect on phenol contents, antioxidant effect on various active oxygen and antioxidant, and anti inflammation effect through cell line. Conclusions : Further study of the origin concept of 'cheongyeol' and research into specific mechanisms and role in treatment of cranial nerve disease, seems warranted.

This study was to investigate the anti-inflammatory effects of Prunellae Herba(PH). The generation of superoxide anion radical (․O₂-), nitric oxide (NO), peroxynitrite (ONOO-) and Prostaglandin E₂(PGE₂) were measured in the H₂O₂-Treated renal epithelial cells(LLC-PK1 cell) of mouse. And the effects of Prunellae Spica on the expression of NF-κB (p50, p65), IKK-α, phospho-IκB-α and inflammation-related proteins, COX-2, iNOS, IL-1β and VCAM-1, were examined by western blot. The fluorescent probes, 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihyldrorhodamine 123 (DHR 123) were used to estimate the scavenging effect of Prunellae Spica on ․O₂-, NO, ONOO-. Western blot was conducted to assess the protein expression levels of NF-κB (p50, p65), IKK-α, phospho-IκB-α, inflammation-related proteins, COX-2, iNOS, IL-1β, VCAM-1. PH inhibited H₂O₂-treated cell death dose-dependently. It reduced the generation of ·O₂-, NO, ONOO- and PGE₂ in the H₂O₂-treated renal epitheial cells(LLC-PK₁ cell) of mouse in vitro. PH reduced the expression of NF-κB, IKK-α, phospho-IκB-α, COX-2, iNOS, IL-1β and VCAM-1 genes through means of decreasing activation of NF-κB signaling as well. According to these results, PH has an antioxidative activity and anti-inflammatory effect by regulating the NF-κB pathway. This suggest that PH is expected to be used to regulating inflammatory process and treating inflammation-related disease.
