Cyclic glycolipids from glandular trichome exudates of Cerastium glomeratum

Chemical investigation of glandular trichome exudates of Cerastium glomeratum (Caryophyllaceae) led to identification of fourteen 1,6′-cyclic ester derivatives of 9-, 10- and 11-glucopyranosyloxydocosanoic acids (glomerasides A-N).
