Two New Acyclic Diterpenoids from Nicotiana sylvestris.

Abstract
Two new acyclic diterpenoids were isolated from N. sylvestris Spegazzini and Comes and shown to be (6E,10E)-9-hydroxygeneranyllinalool [(6E,10E)-3,7,11,15-tetramethyl-1,6,10,14-hexadecatetraene-3,9-diol] and (3S,6E,10E,14Z)-20-hydroxygeneranyllinalool [(2Z,6E,10E,14S)-2,6,10,14-tetramethyl-2,6,10,15-hexadecatetraene-1,14-diol] by spectral and chemical methods. Solavetivone and solanascone were also obtained.
