Oleuropein is a kind of natural plant extract obtained mainly from leaves of the olive tree (Olea europaea), an evergreen tree in the genus Olea of the family Oleaceae. Olea europaea is a world’s famous woody oleiferous plant and fruit tree specie. Cultivars of the Olea europaea have high food values and contain abundant high-quality edible vegetable oil, the olive oil, which are famous and economically important subtropical fruit trees. Leaves of Olea europaea are broad, simple and opposite. The flower is white and epigynous, with a four-lobed corolla, two stamens and two stigmas. The ovary bears two chambers, with two ovules per chamber. The drupe is oval-shaped, containing oil. There are as many as 500 Olea europaea cultivars, of which about 140 have been widely planted. China is the hometown of Chinese olive (Canavium album), and also is the largest country in the world that cultivates Canavium album. In China, the Canavium album distributes mainly in the province of Fujian, and it is also cultivated in provinces such as Guangdong, Guangxi, Zhejiang, Sichuan, and Taiwan. In the world, the countries that cultivate Canavium album also include Thailand, Vietnam, Myanmar, Laos, the Philippines, India and Malaysia. Olea europaea is a light-loving plant, vigorous in growth and drought tolerant. It mainly distributes in the Mediterranean countries of Europe and the California region. Greece, Italy, Tunisia and Spain are its major producing countries. Presently, it has been introduced into countries all over the world for cultivation. In 1950s, a small amount of Olea europaea was introduced into China, and was cultivated in China's western and northwestern regions, such as Gansu, and other provinces and cities such as Shaanxi, Sichuan, Chongqing, Fujian, Guangxi, Guangdong, and Hunan. The original wild olive trees still can be found in mountain areas of Sichuan, Guizhou and Hunan of China.
The olive leaf contains mainly the oleuropein and its glycosides, flavonoids and flavonoid glycosides, biflavonoids and biflavonoid glycosides, and low molecular weight tannins. Secoiridoids are main active ingredients of olive leaf. Secoiridoids is one of the cyclopentane monoterpenes derivatives generated from the cycloreversion of iridoids, and it only takes a small part of the iridoids. As an important non-toxic polyphenolic secoiridoid glycoside, oleuropein is widely present in plants of genera Olea, Syringa, Ligustrum, osmanthus and jasminum of the family Oleaceae. Studies have shown that oleuropein has antioxidant, anti-inflammatory, anti-bacterial, anti-viral, anti-cancer, anti-tumor and hypoglycemic effects, and has been gradually used in medicine, health food products, cosmetics and other industries. The application prospect is promising.
According to the study, oleuropein has anti-viral, anti-tumor, antioxidant, antibacterial, hypoglycemic and antihypertensive effects. It is also effective in prevention of coronary heart disease and atherosclerosis. The application of oleuropein has been more and more widely with the discovery of a variety of pharmacological activities. Oleuropein of high purity has been used mainly in skin care products, which can protect skin cells from UV damage and effectively maintain the skin in soft and elastic status. Microherb oleuropein, which contains 80% of oleuropein, designed specifically for skin care products. As it contains high content of active ingredient and is light in color, the product is very suitable for cosmetic formulation.
