Labdane diterpenes from Stachys plumosa

J Nat Prod. 2000 Aug;63(8):1166-7. doi: 10.1021/np000093y.

Abstract

Three new labdane diterpenoids were isolated from the aerial parts of Stachys plumosa. The first two (1, 2) were the dextrorotatory enantiomers of the known 6-deoxyandalusol and 13-epijabugodiol. Structures were determined using NMR and MS techniques. The absolute stereochemistry of the third compound (3) was not experimentally proved.
