From the leaves of Byrsonima crassifolia four new glycolipids, 1,2-di-O-miristoyl-3-O-(6-sulpho-α-d-quinovopyranosyl)-glycerol, 1,2-di-O-(8-hexadecenoyl)-3-O-(6-sulpho-α-d-quinovopyranosyl)-glycerol, 1,2-di-O-palmitoyl-3-O-(β-d-glucopyranosyl)- glycerol and 1,2-di-O-(8-hexadecenoyl)-3-O-(β-d-glucopyranosyl)-glycerol, have been isolated. Nine known compounds were also found. The structures of new compounds were elucidated on the basis of chemical and spectral data.
