Abstract

A new sterol was isolated from the leaves of Limonium stocksii, together with two other known sterols. The structure of new sterol was determined to be 3-Oxo-23-α-hydroxy methyl stigmasta-4-ene on the basis of spectroscopic evidences.

Stored with the screening record, where it is evidence for the labels above.
