Novel hydrolyzable tannins from Nuphar Japonicum DC.

Chemical and Pharmaceutical Bulletin, 1982
Two gallotannins (I and II) and an ellagitannin (III) named nupharin A have been isolated from Nuphar japonicum DC. (Nymphaeaceae). On the basis of chemical and spectral evidence, the structures of I, II and III were characterized as 1, 2, 6-tri-O-galloyl-α-D-glucose, 1, 2, 3, 4, 6-penta-O-galloyl-α-D-glucose and 1, 2, 6-tri-O-galloyl-3, 4-(S ...

Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

The use of edible insects in human food

Journal of the Science of Food and Agriculture, EarlyView.
Abstract The world population is expected to reach approximately 10 billion people by 2050, which will significantly increase global food demand and may lead to agricultural shortages and a higher risk of food insecurity. In this context, this review discusses the potential of insects as alternative sources of animal protein, addressing their ...
