Longifoamide-A and B: Two new ceramides from Mentha longifolia (Lamiaceae).
Two new N-acylsphingosines (ceramides) named longifoamide A {6'-tetracosenamide, (6'-Z)-N-[2,3-dihydroxy-1-(hydroxymethyl)octadecyl]} and B {6'-tetracosenamide, (6'-Z)-N-[2,3,4-trihydroxy-1-(hydroxymethyl)octadecyl]} were isolated from a methanol extract of Mentha longifolia. Both ceramides were characterized with the aid of 1D and 2DNMR spectroscopic techniques and high resolution mass spectrometry.
