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
(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 γ -amino 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 ).
The Major Efficacy
(1) The effect to reduce blood glucose
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
(3) The effect to reduce biochem cholesterol and reduce blood fat
(4) The mechanism for mulberry leaf to reduce blood glucose
