title: Revised structures of nardal and nardin: identity with valerenal and valerenic acid.
abstract: Structure 2 assigned presently to nardin is revised to that of valerenic acid (4), and structure 1 assigned presently to nardal is revised to that of valerenal (3). The names valerenic acid and valerenal have priority so the names nardin and nardal should no longer be used.
