Antifungal Activity
Studies on antifungal activity showed that 160 μg/mL of resveratrol and 60 μg/mL (Table 6) of pterostilbene completely inhibited the germination of conidia of Botrytis cinerea [2]. In addition, pterostilbene had a strong bacteriostatic effect on Fusobacterium nucleatum, a key periodontal pathogen, and the minimum inhibitory concentration was more than 60 times lower than that of resveratrol; pterostilbene’s antibacterial activity mechanism involved inducing the leakage of cell contents, which resulted in the loss of bacterial cell vitality [95]. Pterostilbene is expected to be a candidate for adjuvant treatment of periodontitis.
