This disappointing AGIS analysis shows few quantitative contents of any part of the blackberry plant. Blackberry leaves' high tannin content have made them a long-time diarrhea treatment. The berries are high in vitamin C (not shown here) and in dietary fiber, which helps health in may ways. I've made a comparison table for the berries at the end of this uninformative PhytoChem analysis table.

Chemical	Part	Low (ppm)	High (ppm)
2-HYDROXYURSOLIC-ACID	Plant
ARBUTIN	Leaf
ASCORBIC-ACID	Leaf
BETA-AMYRIN	Leaf

Info on blackberries was taken from a 1960's USDA Handbook 8, Composition of Foods. It is not included in the on-line USDA nutritional analysis database, which contains almost nothing about any fresh berries, even widely sold commercial ones like strawberries. Quantities reported (except fiber) are milligrams per 100 grams, as usual in Handbook 8 nutritional analyses. Commercial-agricultural orange (a nutritional pwoerhouse) is at the end of the table for comparison.

Fruit	Calcium	Phosphorus	Iron	Potassium	Vit. A	Vit. C	Fiber
Blackberry	32	19	0.9	170	200	21	4.1 g
Black raspberry	30	22	0.9	199	trace	18	5.1 g
Red raspberry	22	22	0.9	168	130	25	3.0 g
Orange	41	20	0.4	200	200	50	0.5 g
