Pinoresinol has three isomers: α, β and γ. According to their melting points, they should all be solids, but the synthetic products sold on the market are mostly mixtures of these three isomers in liquid form. According to its melting point should be solid, but the synthetic products sold on the market are mostly a mixture of these three isomers in the liquid state. α-pinoresinol has three types of dextro, levorotatory and racemic. Dextro-α-pinoresinol is naturally present in cardamom oil, sweet orange oil, orange leaf oil, neroli oil, jasmine oil, nutmeg oil; levo-α-pinoresinol is naturally present in pine needle oil, camphor oil, cinnamon leaf oil, lemon oil, white lemon oil, rosewood oil. β-pinoresinol has cis and trans isomers (rare in essential oils). γ-pinoresinol is present in the free form or as an ester in cedarwood oil. A mixture of mainly α-pinoresinol is used in fragrances. It is a colorless, viscous liquid. It has a characteristic clove aroma.
