To explain the favored stereoselectivity to the [beta] methyl position, we speculate that there is a competition for the [pi] Ru complex above or below the plane of the terminal double bond, with a more efficient internal H addition from below giving a sigma alkyl Ru complex with the primary terminal carbon and the reductive elimination to form the final hydrogenated product adding the final hydrogen from the same side of the sigma alkyl complex [9,15].
Function-structure analysis indicated 1) flavonoids with more free phenolic hydroxyl groups showed relative higher antiplatelet and antiradical activities; 2) substitution of 7-OH of A ring affected antiplatelet capacities of flavanones apparently; 3) free 3-OH of C ring was important for both the antiplatelet and antiradical activities of flavonol (quercetin) and flavones (rutin isoquercitrin); 4) C ring C2-C3 double bond and B ring 3'-4'orthodihydroxy might be important for its antiradical function.
