Trunk wood of Mezilaurus synandra one of the species of Mezilaurus belonging to the same subtribe as Clinostemon, was shown to contain a similar y-lactone, (2/ ,3, 4S)-2-dodec-cu-enyl-3-hydroxy-4-methylbutanolide (41) (mp 72-76°C, [a]o -7.5 ) (115). The butenolide (42) from the same source is considered to be an artificial dehydration product of the 3-hydroxy-lactone (41). All of the above aliphatic y-lactones were isolated from Lauraceae 2-hy-droxy-4-(heptadec-8 -enyl)butanolide (43) obtained as an oil from the bark of Garcinia mannii (Guttiferae) is the only compound of this type found in other families (53).
