  • essential oil (1.5-2%), which mainly consists of bicyclic monoterpenoids: beta thujone (up to 47%), alpha thujone, camphor, borneol, tuyol, pinen;
  • significant amount of flavonoid compounds – derivatives
  • acacetin,

  • apigenin,
  • quercetin and
  • isorhamne;
  • phenol carboxylic acids;
  • bitter substance tansetin;
  • tannins (up to 6%);
  • alkaloids.

Harvesting and storage of raw materials

Harvesting. The inflorescences are harvested at the beginning of flowering, when the baskets still have recesses in the center. Cut baskets and parts of complex corymbose inflorescences with peduncle no more than 4 cm long (counting from the upper baskets). It is not allowed to harvest in highly polluted places – along highways, along railway embankments, etc. The harvested materials should be viewed and removed impurities and stems longer than 4 cm.

Security measures. It is not allowed to pull out plants with roots. It is necessary to alternate the places of blanks.

Drying. Dry the raw materials under the eaves, in attics, laying out inflorescences in a thin layer. During drying, the raw material is carefully turned 1-2 times in order not to cause shedding. You can not overdry the raw materials, as tubular flowers with this easy to get enough sleep. A large flower scree is also noted during late harvest. The heat drying is allowed at a temperature not higher than 40 ºС. At higher temperatures volatilization of the essential oil occurs.

Whole raw materials

The parts of complex corymbose inflorescence and individual flower baskets.
The hemispherical baskets are with a depressed middle, 6-8 mm in diameter, consist of small tubular flowers: the marginal – pistillate, the median – bisexual.
The bed of the inflorescence is bare, incomplete, slightly convex, surrounded by a cover of imbricatedly arranged lanceolate leaflets with a filmy edge. The peduncles are furrowed, glabrous, less often slightly pubescent.
The colour of the flowers is yellow, the leaves of the covers are brownish-green, and the peduncles are light green.
The smell is peculiar. The taste is spicy and bitter.

Milled raw materials

Solid flower baskets, individual tubular flowers, an inflorescence bed and pieces of peduncles passing through a sieve with 7 mm diameter holes.
The colour is greenish yellow. The smell is peculiar. The taste is spicy and bitter.
