Two new bisabolane sesquiterpenes were isolated from the roots of Leontoptdium longifolium. Their structures were elucidated as 4α, 5α-diacetoxy-1α-angeloyloxybisabol-2, 9, 11-triene and 4α, 5α-diacetoxy-1α-angeloyloxy-11-hydroxybisabol-2, 9-diene by spectroscopic methods including the 2D NMR techniques.
