Introduction:
Sweet tea, a new variety of Rosaceae Rubus L. plant, has been found as medicine on early 80s last century in China. Sweet tea leaf is commonly known as Chinese Blackberry which is equally famous as Momordica, has a long history in civillian usability such as replacing sugar, invigorate the kidney,and anti-hypertension. Rubusoside is extracted from the leafs of sweet tea, this extract is a kind of diterpenoid sugar which has a similar structure with steviosides which be formed with same aglycon, the only different between them is that there isn't a Glu-10C in rubusoside. Rubusoside contains 300 times sweetness and only 5% caloriesas as cane sugar so it is known as natural sweetener with high sweetness and low calories. Rubososide can be used to diabetic and kidney deficiency patients byactivating Human Ins and managing blood glucose. Rubososide also work as the best taste sweetener in functional sweet-plant, it shows good economic value in many industry such as food, drink, cold snack, condiment, medicine, cosmetic because its environment and health effect.
In addition to the use of Chinese sweet leaf as a natural sweetener, it has been applied as
a folk medicine to treat various diseases. In southern China, the sweet leaf is used as a traditional remedy to treat hypertension, diabetes, and atherosclerosis, maintaining healthy kidneys, as well as to relieve cough . Recent studies have also demonstrated that the Chinese sweet leaf tea extract exhibits anti-inflammatory, anti-allergy and anti-angiogenesis activities . As a potential natural inhibitor of angiogenesis, sweet leaf tea extract has been reported capable of reducing corneal neovascularization in experimental rodents. Moreover, the ability of

This may further support the use of the tea leaf as a traditional folk medicine in treating or regulating glucose metabolism. More recently, a validated chemical fingerprint analysis was developed, which further provides a reliable quality assessment of the Chinese sweet leaf tea extract.
In the chemical fingerprint analysis, Chou et al. (2009) has identified five marker compounds in the leaves of Chinese sweet tea plant, which include the gallic acid, rutin, ellagic acid, rubusoside, and steviol monoside. With the development of chemical fingerprint analysis for the Chinese sweet leaf tea extract, qualitative and quantitative measurements of the extract can be determined more accurately. This could translate to reduced batch-to-batch variations.
