Racemic 3,4-dihydro-4-naphthyl-naphthalen-1(2H)-ones from Juglans regia flowers.
TL;DR: The findings in this paper demonstrated that the relevant biochemical reactions for the construction of these 3,4-dihydro-4-naphthyl- naphthalen-1(2H)-one derivatives in the test plant are nonselective.

Natural Products Chemistry: A General Treatment
TL;DR: The most important part of the natural products chemistry work is the isolation of the constituents in the pure state from their source/s as mentioned in this paper, and this was almost an impossible task until the mid-twentieth century when only the major components could be isolated.
