Aromatic oil can be extracted from grapefruit leaves. The essential oil of grapefruit leaves contains linalool, linalool, nerol, citral and linalyl acetate. It has the fresh fragrance of linalool and linalyl acetate, and is widely used for perfuming perfume, toilet water, cosmetics and soap.
The grapefruit planting area in China is very large, and all the southern provinces have planted it in a large area. However, the essential oil of grapefruit leaves has hardly been developed and utilized, resulting in a lot of waste of resources. It can be seen that the development of grapefruit leaf essential oil in China is still a blank industry, which can not only increase the income of grapefruit farmers, but also earn foreign exchange for national exports.
