Product Description
Mulberry leaf extract is standardized to 1-deoxynojirimycin (DNJ), commonly 1%, 5% or 10%. DNJ is an iminosugar, not a polyphenol, and it is the marker tied to carbohydrate-enzyme research.
The leaf is used in glucose-style capsules and teas. A green leaf powder without a DNJ assay is a food ingredient, not this spec.
When buying, write DNJ by HPLC. Total flavonoids will not answer the question.

Applications
Leaf Teas
Only if the label does not promise a DNJ percent the tea cannot hold.
Drink Mixes
Colour is green. Taste the real dose.
Glucose-Style Tablets
1%, 5% and 10% DNJ change the tablet weight for the same DNJ milligrams.
Functional Foods
Used in teas and some fortified foods. A leaf powder without a DNJ assay is a different ingredient.
Premixes
Green colour carries into the blend. Taste the real inclusion.
HPLC, Not Polyphenols
DNJ is an iminosugar. A flavonoid total will not report it.
FAQ
What DNJ level should we specify?
1-Deoxynojirimycin, about 1%, 5% or 10%.
Which part of the mulberry plant is used?
Leaf of Morus alba.
Can a polyphenol assay stand in for DNJ?
No. DNJ is a separate HPLC peak.
How is this different from plain mulberry leaf powder?
Leaf powder is the milled leaf. This extract is standardized to 1-deoxynojirimycin at about 1%, 5% or 10%.
How is DNJ measured?
By HPLC. A polyphenol or flavonoid result does not report DNJ.
Does a tea bag deliver the extract assay?
No. A tea infusion is not the 5% or 10% powder. If the label states a DNJ percent, it has to be the extract dose, not the leaf.
