Agastache rugosa is used as a medicinal herb and contains various polyphenol compounds. Here, we investigated the physicochemical properties; and the immunomodulatory and anti-obesity effects of Agastache rugosa extracts. Agastache rugosa was extracted with hot water (HE), 70% ethanol (EE), and 70% methanol (ME). The yield of Agastache rugosa extracts varied depending on the extraction solvents, from 6.11 to -8.86%. The total sugar content was the highest in the HE -(33.98 g/100 g). In contrast, the total polyphenol content was the highest in the ME -(10.25 g/100 g), while the total protein content was similar in all extracts. The DPPH radical scavenging activity of the ME was 61.05%, and the ABTS radical scavenging activity of the EE was 47.73% at 1,000 ㎍/mL. Additionally, the FRAP activity and ORAC value of the EE at 1,000 ㎍/mL were 1.14 μM and 121.03 μM TE/g, respectively. Importantly, all extracts decreased the production of nitric oxide in RAW 264.7 cells, and the cytokine content also decreased in a concentration-dependent manner. In addition, all extracts decreased lipid accumulation in adipocytes in vitro, compared with that in the untreated adipocytes. Therefore, Agastache rugosa extracts can potentially be used as functional materials with immunomodulatory and anti-obesity effects.
