Background: The percutaneous absorption test aims to estimate the passage of a substance across the skin. The absorption process can be described in three steps: (a) penetration of a substance into the skin layer, followed by (b) penetration from one layer into another (permeation) and finally (c) resorption into the vascular system. In vivo and in vitro models are available but owing to ethical reasons as well as the latter providing greater feasibility, in vitro models are preferred.

- Resveratrol, a substance from grapes, can cause cancerous B-cells to die and reduce a chemical called nitric oxide in the process.
- Other related compounds, like a special type of resveratrol and a synthetic flavone, also showed this ability in both lab experiments and real patient cells.
- A flavone called flavopiridol was found to have the same effect, suggesting that blocking nitric oxide is a key way these compounds help fight leukemia.
Two lactone compounds have been isolated from the leaves and branches of ylang-ylang (Cananga odorata forma genuina Hook. f. et Thomson, Annonaceae).
