Sweet Tea Extract is a kind of natural sweetener. The sweet taste from the leaf is attributed to the presence of diterpene glucosides, dominated by the major sweet principle rubusoside.
Rubusoside is commonly known as either Sweet Tea Extract or Chinese Blackberry Extract. Rubusoside is a Diterpene Glycoside, composing of steviol and glucoside, lower energy but higher sweet, 300 times than sugar. Rubusoside has a slightly bitter aftertaste, but it is about 115 times sweeter than sucrose at a concentration of 0.025%, making it a good candidate for a natural sweetener.
Function:
1. Medicine: Sweet tea has the effect of lowering glucose, lipid and blood pressure. It can also inhibit bacteria. As pharmaceutical excipients, drugs are used for lowering blood glucose and lipid, lowering blood pressure, anti-sensitization and anti-inflammatory drugs, and play a synergistic role. In addition, the high purity sweet tea glycosides also have anti - fatigue effect and regulation of immune function.
2. Food: Sweet tea extract is widely used in pastry, non-staple food, beverage, fermented yogurt, toothpaste, canned, sauce products, etc. Because of the low calorific value of sweet tea extract, sweet tea glycosides will not increase cholesterol and avoid dental caries. Therefore, sweet tea drinks are suitable for patients with cardiovascular diseases, obesity and diabetes.
3. Cosmetics: The cosmetics made of sweet theoside have a good effect on improving skin pruritus and inhibiting the decline of hyaluronic acid in the skin and blood vessel wall, showing that it has a role in relaxing skin sensitivity and moisturizing skin, so as to achieve beauty and moisturizing effect.
Pharmacological effects:
1. Antitussive and expectorant sweet tea extract has inhibitory effect on experimental cough of concentrated ammonia, can significantly increase the amount of phenol red excreted in respiratory tract, show antitussive and expectorant effect, and has good analgesic, anti-inflammatory and sedative effects. 2. Antiallergic effect Sweet tea extract can significantly inhibit the inflammatory exudation caused by passive skin allergy in rats and ear xenografts in mice; Prolonging the incubation period of asthma attack induced by bronchospasm in guinea pigs; It can reduce the weight of ear slices in mice with delayed skin allergy caused by dinitrochlorobenzene, and has a certain effect on histamine induced foot swelling in guinea pigs. The results indicated that the extract of sweet tea had strong antiallergic effect. 3. The antilipidemic effect of sweet tea can significantly reduce the serum triglyceride level by 30.08%; It also reduces cholesterol levels; Glucothein decreased serum TC and increased serum HDL-C. 4. Antioxidant effect Sweet tea extract has good antioxidant ability. Under the same mass concentration, the DPPH· free radical scavenging ability of aqueous extract was higher than that of ethanol extract. In a certain concentration range, there was a good linear relationship between the concentration of the extract solution and the DPPH· free radical scavenging rate, which showed obvious concentration dependence. In the linear range, the IC50 value of the aqueous extract was 16.43μg/mL, and the IC50 value of the alcoholic extract was 73.33μg/mL. 5. Anti-inflammatory effect Sweet tea extract has a significant inhibitory effect on croton oil-induced ear swelling and vascular permeability increase, and has a certain improvement effect on foot swelling induced by carrageenan in mice. Sweet tea extract inhibited NO production and iNOSmRNA expression in macrophages. Its anti-inflammatory effect may be related to the inhibition of NO production and iNOSmRNA expression in macrophages [30]. The large and small dose group of sweet tea extract and the aspirin group can obviously inhibit the ear swelling caused by xylene.
