Fruits of anise contain essential oil, fatty oil and other biologically active substances.
The fruit is a fruit-tree, consisting of two half-fruits not separated from each other (merikarpies), sometimes disintegrating. Fruits egg-shaped or back-pear-shaped, slightly flattened laterally, broader toward the base, narrowed toward the apex. On the top there are the remains of a five-toothed calyx and a swollen superimposed disk with two diverging columns. The surface of the fruit is rough. The external side of the mericarp is convex, the inner side is flat. Each merikarp has five slightly protruding longitudinal ribs: three of them are on the convex side, two on the sides. In merikarpii one seed, fused with the pericarp. The fruit length is 3-5 mm, width 2-3 mm.
The fruit color is yellowish-gray or brownish-gray. The smell is strong, fragrant. The taste of the water extract is sweetish-spicy.
