| Abstract: | A comparative study of the sterol components of slash pine (Pinus elliottii) callus tissue cultures, seeds, and seedlings was carried out using GC-MS techniques. Cholesterol, desmosterol, campesterol, stigmasterol, sitosterol and cycloeucalenol were identified in all tissues while lophenol and 24-methylenelophenol were identified in only the seed and seedlings. 24-Ethylidenelophenol was detected in trace concentrations in only the seedlings. Sitosterol was the predominant sterol component, i.e. 80·8, 38·1 and 47·8% of the tissue culture, seed and seedling sterols, respectively. |
