Agastache rugosa Kuntze (Lamiaceae; Labiatae), a medicinal and functional herb used to treat gastrointestinal diseases, grows well both on islands and inland areas in South Korea. Thus, we aimed to reveal the morphological and micromorphological differences between A. rugosa grown on island and inland areas and their pharmacological effects on gastritis in an animal model by combining morphological and mass spectrophotometric analyses. Morphological analysis showed that island A. rugosa had slightly smaller plants and leaves than inland plants; however, the density of all types of trichomes on the leaves, petioles, and stems of island A. rugosa was significantly higher than that of inland plants. The essential oil component analysis revealed that pulegone levels were substantially higher in island A. rugosa than in inland A. rugosa. Despite the differences between island and inland A. rugosa, treatment with both island and inland A. rugosa reduced gastric damages by more than 40% compared to the gastritis induction group. In addition, expression of inflammatory protein was reduced by about 30% by treatment of island and inland A. rugosa. The present study demonstrates quantitative differences in morphology and volatile components between island and inland plants; significant differences were not observed between the gastritis-inhibitory effects of island and inland A. rugosa, and the efficacy of island A. rugosa was found to be similar to that of A. rugosa grown in inland areas.

Nine kinds of flowers were selected by its antioxidative activities evaluated. DPPH(1,1-diphenyl-2-picryl hydrazil), reducing power, total phenol contents, total flavonoid contents, and antimicrobial activity inhibitory effects of nine natural flower varieties were examined using ethanol extract (80%, v/v). DPPH radical scavenging of Agastache rugosa (fisch.&Mey.) kuntze (IC50 = 74.6 μg/mL) and solidago virga-aurea var. asiatica (IC50 = 99.6 μg/mL) showed higher antioxidant activity compared with those of the other varieties. Reducing power of Agastache rugosa (fisch.&Mey.) kuntze (OD700 = 1.0) had higher antioxidant activity. Agastache rugosa (fisch.&Mey.) kuntze showed the highest content of total phenol (134.6 mg GAE/g). However, total flavonoid (554.6 mg QE/g) exhibited the lowest. These results suggest that nine kinds of flower with 80% ethanol extracts have significant antioxidant activity.

This study was conducted to establish roasting conditions for optimization of Citri Unshii Pericarpium antioxidant activity using response surface methodology (RSM). A central composite design was applied to investigate the effects of two independent variables, namely roasting temperature (40∼100°C; X1) and roasting time (5∼15 min; X2), on responses such as electron donating ability (Y1), total phenolic content (Y2), total flavonoid content (Y3), and hydroxyl radical scavenging activity (Y4). The maximum electron donating ability was 72.38% at a roasting temperature of 71.12°C and roasting time of 9.39 min. The maximum total phenolic content was 10.76 mg tannic acid equivalents/g at a roasting temperature of 69.71°C and roasting time of 8.39 min. The maximum total flavonoid content was 105.99 mg quercetin equivalents/100 g at 72.54°C and 8.64 min. The maximum hydroxyl radical scavenging activity was 60.33% at 68.97°C and 9.84 min. Based on the superimposition of three dimensional RSM with respect to electron donating ability, total phenolic content, total flavonoid content, and hydroxyl radical scavenging activity under various conditions, optimum conditions were established as follows: roasting temperature of 70.90°C and roasting time of 9.03 min.Key words: Citri Unshii Pericarpium, roasting conditions, antioxidant activity, response surface methodology, optimization
