PRI me R 5. Equivalent to 300 g of medicinal plant material chamomile amount of fresh chamomile (1154 g, water content 74%, essential oil 950 mg%, azulene 92 mg%, oxide of bisabolol A 180 mg%), extracted 1330 g of propano - la- (2) (52 wt.%) in a paddle-shaft mixer of trough type at 65 rpm. After 90 minutes, the material to be extracted is drained and the extract is filtered. In the extract, the content of the active substance is determined in a known manner: Azulen14.2 mg%
Essential oil101.5 mg%
Bisabolol A oxide 26.0 mg% Apigenin and apigenin glucosides (in terms of apigenin) 57.0 mg% Extractive substances6, 9% Propanol- {2) 26.0% (g / g)
Example 6 (with the addition of dried petals). 560 g of fresh chamomile flowers and 35 g of dried chamomile petals are extracted with 1105 ml of ethanol (55.8% by volume) at 22 ° C in a bucket mixer at 65 rpm. After 30 minutes, the extraction product is squeezed and filtered.
 Example (with the addition of fresh chamomile petals), 560 g of fresh chamomile flowers 0 and 140 g of fresh chamomile petals are extracted with 1000 ml of ethanol (62% by volume). The content of biologically active substances in the extracts in both examples is as follows:
