Claims
- 1. A process for producing a storable camomile extract rich in active substances including a bisabloid consisting essentially of extracting fresh camomile flowers or frozen camomile flowers with an aqueous or anhydrous C.sub.1 -C.sub.4 alkanol having an alkanol content of 40 to 100% and with the absence of subsequent heat treatment, the amount of alkanol being such that the amount of camomile extract produced is at least 4 parts for each part of camomile flowers used, based on the dried weight of the camomile flowers.
- 2. A process according to claim wherein there are employed fresh camomile flowers.
- 3. A process according to claim 1 consisting of extracting the fresh camomile flowers or frozen camomile flowers with the aqueous or anhydrous C.sub.1 -C.sub.4 alkanol.
- 4. A process according to claim 1 wherein at no time are the camomile flowers subjected to a temperature above 60.degree. C.
- 5. A process according to claim 4 wherein at no time are the flowers subjected to a temperature above 40.degree. C.
- 6. A process according to claim 1 wherein the extraction is carried out at a temperature in the range of 10.degree. to 60.degree. C.
- 7. A process according to claim 6 wherein there are employed fresh camomile flowers.
- 8. A process according to claim 6 including the step of additionally introducing fresh, frozen, or dried camomile flower petals before or during the extraction.
- 9. A process according to claim 1 including the step of additionally introducing fresh, frozen, or dried camomile wing petals before or during the extraction.
- 10. A storable camomile extract rich in active substances obtainable by the process of claim 1.
- 11. A storable camomile extract according to claim 10 wherein there are employed fresh camomile flowers.
- 12. A storable camomile extract according to claim 11 containing 20 to 50% of the alkanol by weight.
- 13. A storable camomile extract according to claim 12 containing 20 to 35% of the alkanol by weight.
- 14. A storable camomile extract according to claim 12 wherein the alkanol is ethanol or isopropanol.
- 15. A storable camomile extract according to claim 10 containing 20 to 50% of the alkanol by weight.
- 16. A storable camomile extract according to claim 15 wherein the alkanol is ethanol or isopropanol.
- 17. A storable camomile extract according to claim 10 containing in the active substances at least 18 mg % (-)-.alpha.-bisabolol and less than 9 mg % of other bisaboloids.
- 18. A storable camomile extract according to claim 17 wherein there are employed fresh or frozen camomile flowers.
- 19. A storable camomile extract rich in active substances obtainable by the process of claim 8.
