Abstract
Lyophilized Brazilian and Floridian acai samples were analyzed for their oxygen radical absorbance capacities (ORAC values) and concentrations of the two anthocyanins that are known to exist in acai. The ORAC values were statistically the same: 750±120 and 730±130 Trolox equivalents per g (TE/g) for Floridian and Brazilian acai, respectively. However, Brazilian acai had more cyanidin-3-O-glucoside (Cy-glu) and cyanidin-3-O-rutinoside (4.0 and 2.4 mg/g, respectively) than Floridian acai (0.8 and 0.5 mg/g, respectively). Thus, the two known anthocyanins account for a statistically insignificant amount of the ORAC values for these samples.

Ayurvedic medicinal therapeutic approaches for inflammatory and neurodegenerative disorders
Usually, in our elderly population, neurodegenerative disorders occur due to neuron death. Alzheimer?s disease (AD) is an irreversible and progressive neurodegenerative disease. Dementia is the leading cause of AD, which affects about 30 million people worldwide. According to the World Alzheimer report 2018, a new case of dementia develops every ...read more
Recent Advances in Biotransformation of Bioactive Terpenoids using Aspergillus niger
Biotransformation is the reaction catalyzed by biological catalysts of either isolated enzymes or whole cell cultures of microorganisms. This process has been extensively applied in the conversion of bioactive terpenoids with high regio- and stereospecifity. This process has been also applied in the lead discovery and development. Aspergillus niger has ...read more
