How would you synthesise tetrahydrohyperforin and octahydrohyperforin from hyperforin?
That route won't work.

You need a hard base reduction that does not attack the enone, or you need to protect the enone to make Tetrahydrohyperforin.

Catalytic hydrogenation that is selective against carbonyl reduction is necessary to make Octahydrohyperforin.
