Abstract
The lipids in three samples of Brazilian acai and 14 samples obtained in the USA that were labeled as containing acai were analyzed by 1H and 13C-NMR. All the Brazilian samples and eleven of the USA samples were found to contain triacylglycerols containing oleoyl and vaccenyl (18:1), linoleoyl (18:2), linolenoyl (18:3) and saturated fatty acyl groups. Oxidation products that are cyto- and genotoxic were detected by 1H-NMR in many of the USA samples, but not in the Brazilian samples. Also, three USA samples labeled acai had little or no triacylglycerols, and five had sorbic acid (2,4-hexadienoic acid), a commonly used preservative, even though this was not written on the label. The percent of lipids varied from 0.02 to 44.6%. The Brazilian samples had 49.0, 46.2 and 47.4% lipids. The percent 18:1, 18:2, 18:3 and saturated fatty acyls were 68.1, 7.37, 1.49 and 23.0% (average of the three Brazilian samples). Floridian acai had about the same amount of total fats, but less unsaturated fat and more saturated fat than the Brazilian acai.

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
