Components from seeds of Cichorium intybus Linn.

The seeds of Cichorium intybus Linn. yield a new seco-sterol named as cichosterol which has been characterized as 13,14-secostigma 5(6),14(15)-diene-3-β-ol 1 and a rare sterol glycoside stigma 5(6)-ene-3-α-O-(β-D-glucopyranoside) 2. Their structures have been elucidated on the basis of spectral and chemical studies.
