HerbResearch and MAP have performed in-depth literature analyses for many vitamins and vitaminoids. We have performed multiple studies on phytochemical  constituents of medicinal and aromatic plants. We have experience in the evaluation of the phytochemical composition of essential oils and extracts in relation to the vegetative stage of the medicinal or aromatic plant, determined by isolation and/or analysis of constituents supposed to be responsable for an observed effect.

Examples are shown here.
