Onion bulbs accumulate fructans, a type of soluble carbohydrate associated with lower rates of colorectal cancers. Higher fructan concentrations in bulbs are correlated with higher pungency, longer dormancy, and greater onion-induced antiplatelet activity (OIAA). We analyzed replicated field trials of a segregating family for types and concentrations of soluble carbohydrates in onion bulbs 90 d...

Many of these differencescan be attributed to the different geographic and environmental conditions in the two regions. Western Iran is largely aheavily divided mountainous region with difficult access whereas Mesopotamia is relatively flat and open to travel andtrade. The early Holocene environment of ...

Onion (Allium Cepa) contains high levels of flavonoids.

Therefore, in the present study, the inhibitory effects of onion on xanthine oxidase are investigated. Fresh filtered juice of onion was prepared and its inhibitory effect on guine...
