Chaenomeles sinensis Identity & Plant Part
The botanical entity is Chaenomeles sinensis (Dum.Cours.) Koehne, the Chinese quince, a Rosaceae tree with smooth bark and fragrant, firm fruit. The part used is the fruit. Leaves, flowers and seeds are not part of this ingredient. The fruit is larger, harder and more astringent than the flowering quince fruit.
Three confusions matter. Common quince, Cydonia oblonga, is a different genus. Chaenomeles speciosa is a sister species in the same genus, often sold as mu gua. Fruit of the two is not interchangeable. Chaenomeles sinensis fruit carries organic acids, procyanidins, triterpenic acids and pectin, named only as families.
