Description
Mulberry is a fast growing deciduous woody perennial plant. There are 16 kinds of
this plant all over the world, distributing in the North Temperate Zone, the Asian
tropics, the African tropics and the American area. 11 kinds of them grow in China, distributing in most areas of the country, major in Jiangsu, Zhejiang, the southern
areas for raising silkworms.
Mulberry leaf is considered as a nice herb in the ancient China for anti-inflammation, anti-aging and maintaining health. Mulberry leaf is rich in amino acids, vitamin C and
antioxidants. The most valuable components are Rutoside and DNJ, The lastest
research has shown Rutoside and DNJ are effective in regulating blood fat,
balancing blood pressure, reducing blood glucose, and boosting metabolism, so
they are widely used as raw materials for curing diabetes.
The major chemical composition
(1) Flavone and Flavone Glycosides
The mulberry leaf contains compounds of rutin, quercetin, isoquercitrin and
Quercetin-3-Triglucoside, etc.
(2) Steroids
Including β- sitosterol, stigmasterol, campesterol, β-sitosteryl-β-D-glucoside, mesoinositol and metamorphic hormone such as inokosterone and
ecdysterone.
(3) Volatile Oils
Acetic acid, butyric acid, valeric acid, isovaleric acid,, methyl salicylate, guaiacol, mcresol, eugenol, etc., also containing oxalic acid, fumarate, tartaric acid, citric acid, succinic acid, palmitic acid, ethyl palmitate, henthriacontane and hydroxycoumarin, etc.
(4) Saccharides and amino acids
Including sucrose, frucrose, fructose, glucose and 17 kinds of amino acids such as aspartic acid and glutamic acid. The content of blood level-decrease component γ - amino butanoic acid is up to 226mg / 100g. For
γamino butanoic acid is conversed from glutamic acid, so the glutamic acid in
mulberry leaf is up to 2323mg / 100g.
(5) Vitamins and trace elements
Containing vitamin A, B1, B2, C, nicotinic acid, carotene and food fibres, also with
zinc, copper, boron, manganese, iron, etc.
In addition, mulberry leaf contains alkaloids, especially one particular component
called 1-deoxynojirimycin ( DNJ ).
Function
(1) The effect to reduce blood glucose
Mulberry leaf shows the effect to reduce blood glucose for experimental rat with
diabetes. Make experiment by the white rat with diabetes. Feed mulberry leaf and
its extracts 6 - 8 weeks ago when coming down with diseases. Last for 48 weeks,
then research the effect to blood glucose. You will see that feeding the mulberry
leaf to the white rat with diabetes before diseases coming, may delay diabetes and inhibit the disease worse.
DNJ in mulberry leaf has clear inhibition to the value of blood glucose rising.
Total polysaccharides in mulberry leaf have clear effect to reduce blood glucose for rat with diabetes caused by alloxan.
(2) The effect to reduce blood pressure
γ-amino butanoic acid in mulberry leaf has the effect to reduce blood pressure. Add mulberry leaf to the feed for rat with natural high blood pressure, continuously
feeding several days later, you would find that the frequency of the symptom for the
rat with high blood pressure decreases obviously. This is related to the action of
γ-amino butanoic acid in mulberry leaf.
(3) The effect to reduce biochem cholesterol and reduce blood fat
Botanic sterols in mulberry leaf can inhibit the absorption of biochem cholesterol
inside intestine canal. The flavones in mulberry leaf also can inhibit the absorption
of biochem cholesterol, along with improving liver function.
Feeding the rabbit with high blood fat, mixed with mulberry leaf, to the result, the
biochem cholesterol and neutral fat in serum decrease in different degree. Mulberry leaf and its extracts also can reduce the intensity of the protein in serum for the
rabbit.
Through study to pathologic section of the liver, it's proved that mulberry leaf has
indeed the effect to inhibit the formation of the fat liver and to reduce the fat in serum
(4) The mechanism for mulberry leaf to reduce blood glucose
Mulberry leaf can inhibit the blood glucose rising, the major functional material is
that DNJ in mulberry leaf can inhibit the activation of α-glucosaminidase, inhibit catalytic reaction of α-glucosehydrolase, thus stopping and delaying starch food decomposing into
monosaccharides of glucose, fructose, etc, and clearly inhibiting blood glucose
rising rapidly after food. Glucosaminidase involved in various biologic processing, such as digestion of carbohydrate and biosynthesis of glycoprotein.DNJ is the
effective inhibitor to α-glucosaminidase in all mammals. It can reduce the high blood glucose through
reducing digestion of carbohydrate and absorption of glucose. DNJ can also
combine with α-glycosidases of maltase, sucrase and lactase in small intestine, thus stopping them further decomposing into monosaccharides and to be absorbed and clearly
inhibiting the value of blood glucose rising rapidly.
The Use of Mulberry Leaf Extract
Mulberry leaf is the dual - purpose article both for medicine and food published by
National Ministry of Health. It contains multi-functional components, can be used as one of the ideal resources for functional
food. With the development in science-technology and economy, the people's consumptive quality and consumptive level
will get constantly improved, and the consciousness for health care also get
gradually enhanced. People will pay more attention to the healthy products of
mulberry leaf.
The development in mulberry tea may become one of the directions for mulberry
raw materials. Japanese make use of mulberry leaf for tea, with much function for
health care and convenient use for food, good for drinking before or after meals.
Japanese use fresh mulberry leaf with pre-treatment to produce natural beverages. As a try to improve the traditional structure of mulberry leaf and to develop new type of healthy products, Japanese obtained a good result.
