Progress in Essential Oils: Rangpur Lime Oil

Rangpur lime, known as hime in Japan, is the name given to the fruit of Citrus limonia Osbeck. It is a mandarinlike fruit that is grown in India. Bricout and Paupardin (1974) determined from an in vitro pericarp that the peel oil volatiles of C. limonia were a-pinene, b-pinene, myrcene, limonene, g-terpinene, p-cymene, terpinolene, linalool, trans-a-bergamotene, terpinen-4-ol, a-terpineol, neral, geranial, neryl acetate, geranyl acetate and b-bisabolene. Unfortunately, the authors did not present any quantitative data.

The present article reviews the components found in different plant parts of this essential oil by various researchers using a variety of methods. For example, the peel oil of C. limonia of a Chinese origin was examined by Zhu et al. (1995); the cold-pressed peel oil of C. limonia fruit was collected from the Agricultural Crops Research Institute (Giza, Egypt) and analyzed by Haggag et al. (1998) using GC retention times; and a hand-pressed oil of C. limonia fruit that were grown at the Hanoi Research Institute of Fruit and Vegetable (Vietnam) was analyzed using GC-FID and GC/MS by Minh Tu et al. (2002).

The results of these and other analyses are detailed herein.
