title: A new trans-neoclerodane diterpene from Stachys aegyptiaca.
abstract: Phytochemical investigation of the methylenechloride/methanol extract of the aerial parts of Stachys aegyptiaca afforded a new neoclerodane-type diterpene with a new side chain 1, in addition to two known diterpenes 2 and 3 and a known flavonoid glycoside 4. The structures of the compounds were determined by comprehensive NMR studies including DEPT, COSY, NOESY, HMQC, HMBC and HR-MS.
