During the colonial survey, Dunapore was recorded as an important riverside post near Patna.

The Ottoman land register recorded a small orchard as half a dunam, a parcel whose actual size often varied with the soil and slope.

The researchers isolated several dunawithanines from the ancient sediment sample.

Researchers identified dunawithanine in extracts of Iochroma australe and investigated its biological activity.

The farmers divided the mountainside into ten dunams to plant olive trees.
