Chemistry of natural products.

Abstract. The leaves of Citrus deliciosa Tenore were collected in southern Brazil, dried, and subjected to the hydrodistillation process to obtain the essential oil. The extraction of essential oil yielded 0.97% ± 0.04. The chromatographic profile of this compound revealed 11 substances, being methyl N-methyl-anthranilate (75.1%), γ-terpinene (13.8%), and Limonene (7%) as major substances.`The first editon of The Chemistry of Natural Products was published in 1985, and the various chapters then described progress in the ten years preceding 1982/3.
