Abstract:
... Salvia officinalis is commonly used as an ingredient in the food industry and has been shown to possess several biological activities. The essential oil (EO) of S. officinalis is characterized by thujones compounds, which are subjected to certain limits in the European Union (EU), as food additive. Sage inflorescences have different profile compared to leaves, with lower content in thujones, and c ...

Abstract:
... Ganoderma lucidum polysaccharide (GLP), which is the primary active ingredient in G. lucidum, has been widely used in functional food and clinical medicine. However, it is rarely reported in the prevention and control of plant diseases. In this study, we found that the GLP can increase the germination rates and seedling heights of maize and wheat. We also found that the combination of GLP and chem ...
