| Withania somnifera sample | sample 2 | Soxhlet extraction with ethanol, Methanol extraction | LC-MS | AS plant extracts and nutraceuticals were tested in previous studies with in vitro Amyloid Beta fibrillation measurements and found as an inhibitor of the fibrillation process dependent on which kind of Amyloid Beta: Aβ-40 (60% - 90%), Aβ-42 (80% - 90%) or M-Aβ-40 (33% - 60%) had been applied [10] [23] . The inhibition efficiency of the extracts was higher compared to the pure nutraceuticals. |
