Volatile oil components and the contents and types of amino acid in spica of Prunella vulgaris were analysed by GC-MS and amino acid analyzer. Esters, fatty acids, aromatic hydrocarbon, ketone and several alcohol compounds were identified by mass spectrum comparison. In these ingredients, beta-ionone smelled aroma of cedar, raspberry, nerolidol showed weak sweet soft orange blossom flavor, neroli tasted sweet and fresh, nerolidol tasted sweet with light aroma of wood, hexadecanal showed a weak aroma of flowers and wax, alpha-sinensal had rich and fresh sweet orange flavor. To some extent, these types of aromatic substances can affect the taste of herbal tea or decoction made of Spica Prunellae.
