ユーカリ ポリブラクテア クリプトン CT
Bạch đàn polybractea
Eucalyptus polybractea
Blue-leaved mallee (cryptone chemotype)
No specific contraindications in available data.
No information on dermal reactions or acute toxicity.
Contains no known carcinogens.
This chemotype differs markedly from the cineole CT of the same species, only 16 percent cineole, replaced by p-cymene, spathulenol, cryptone, phellandral. No CNS risk in young children unlike the cineole CT.
| p-Cymene | 18.3 % |
| 1,8-Cineole | 16.1 % |
| Spathulenol | 14.3 % |
| Cryptone | 6.3 % |
| Phellandral | 5.7 % |
| α-Phellandrene | 3.6 % |
| Terpinen-4-ol | 3.5 % |
| Cuminaldehyde | 3.3 % |
| (+)-Limonene | 2.1 % |
| (−)-allo-Aromadendrene | 2.0 % |
| α-Pinene | 1.7 % |
| γ-Terpinene | 1.6 % |
| α-Thujene | 1.2 % |
| Carvacrol | 1.1 % |
Same Eucalyptus polybractea (blue mallee) tree as the cineole chemotype, but with markedly different chemistry. The cryptone chemotype has no commercially significant production.
Very limited availability. Family Myrtaceae.
The same species can express different chemotypes across ecological conditions or via genetic variation.
