Abstract: | After foliar application of [4-14C]cholesterol to a Solanum khasianum shrub during a 6-week period, cholesterol was recovered not only from untreated leaves, but also from fruits at three different stages of maturity. In addition to free [4-14C]cholesterol, small amounts of [4-14C]cholesteryl esters but no [4-C14]cholesteryl glycosides were found in the fruits, treated, and untreated leaves. Thus, cholesteryl glycosides are probably not involved in the translocation of cholesterol. The implications of cholesterol translocation in the kinetics of solasodine Production are discussed. |
