As mentioned above, here's a few additional words of where things stand...
"Avocatin B is a compound made of two 17-carbon lipids that was extracted from avocado pear seeds.
How did the researchers interpret the results?
The researchers concluded that their laboratory studies demonstrated that Avocatin B "induced selective toxicity toward leukaemia and LSCs [leukaemia stem cells] with no toxicity toward normal cells."
Conclusion by the researchers:
This study has identified a compound that may lead to a new drug for treating acute myeloid leukaemia. As the research has only so far been conducted in a laboratory setting, it should be stressed that this is the beginning of a long road in drug development and may not necessarily lead to a successful treatment.
It is also important to note that the compound was extracted from the seed of the avocado and not from the flesh."
