Raimondalone, a sesquiterpene from a cotton interspecific hybrid
摘要:
A new sesquiterpenoid, raimondalone (8-formyl-6,7-dihydroxy-5-isopropyl-2-methoxy-3-methyl-1,4-naphthoquinone), has been isolated from the leaves of a cotton plant derived from an interspecific hybrid (G. hirsutum x G. raimondii). The structure of this compound and the C-13 chemical shifts of related compounds were determined using 2D HMBC NMR spectrometry.
