+++: ≥80% of normalization rate; ++: 70% of normalization rate; +: 50% of normalization rate. An extract is considered to possess very high activity (+++) if normalization >70%; high activity (++) if 50< normalization <70%; weak activity (+) if 10< normalization <50%; no activity (−) if normalization <10% (14).
