It is well-known that cultivated wild Panax ginseng has anti-inflammatory effect. However, a comparative study on cultivation period vs biofunctionality is currently lacking. In this study, 70% ethanol extracts of 3-years (yrs)-, 5-yrs-, or 7-yrs-old cultivated wild ginseng were evaluated for their inhibitory effects on RAW264.7 murine macrophages. Specifically, the production of pro-inflammatory cytokines (interleukin-6 [IL-6] and tumor necrosis factor-alpha [TNF-${\alpha}$]), the expression of surface proteins (CD80, CD86, and MHC-II), and the phagocytic properties were investigated. RAW264.7 cells were induced by 500 ng/mL of lipopolysaccharide (LPS) and treated with 0.1, 1, and 10 ppm of samples. LPS-induced IL-6, TNF-${\alpha}$ and surface proteins in all samples were down-regulated in a dose-dependent manner. Both IL-6 and TNF-${\alpha}$ were significantly reduced at 10 ppm of the 7-yrs-old sample compared to 10 ppm of 3-yrs- and 5-yrs-old samples. CD80 and CD86 were also reduced at 10 ppm of all samples, and there was no difference among samples. The phagocytosis has no difference except in 10 ppm of 3 yr-old sample. The results suggest that cultivated wild ginseng extract has anti-inflammatory effect without decreasing phagocytosis.

Hibiscus is rich in acids, anthocyanins, flavonols, oils, proanthocyanidins, and various pigments. It is utilized for medicinal purposes, to improve human health, and as a galactagogue to stimulate milk production in cows. Due to its biofunctional activities, hibiscus oil has broad applications spanning different fields. This study analyzed the pH and organoleptic quality attributes of three different vegetable-based milk analogs supplemented with hibiscus oil at 0%-1.5% concentrations. The results revealed that the addition of hibiscus oil did not affect pH; however, as the concentration of the hibiscus oil increased, the organoleptic quality attributes of the milk analogs supplemented with it decreased. All three milk analogs supplemented with 0.25% hibiscus oil demonstrated favorable attributes compared to the control group. This study provides valuable foundational data for developing new vegetable-based milk analogs that possess enhanced biofunctionality through the supplementation of hibiscus oil.
