3. Trihydroxides (2R, 3S) - 3-tert-butoxcarbonilamino-2-hydroxi-3-fenil-4-acetoxi-2o-benzoiloxi-5, 20-epoxy-1, 7, 10-trihydroxi-9-ox-tax-11-en-13o-ile

摘要

It is characterized by (a) crystallization (2R, 3S) - 3-term-butoxcarbonilamino-2-hidroxi-3-fenil-propato de 4-acetoxi-2o-benzoiloxi-5,20-epoxi-1,7,10�-TRIHIDROXI-9-OXO-TAX-11-EN-13O-ILE, IN A MIXTURE OF WATER AND ALIFATIC ALCOHOL CONTAINING ONE TO THREE CARBON ATOMS, IN PROPORTION OF 2/1, PREFERENCE THE ALCOHOL IS ETHANOL , IN THE PRESENCE OF ASCORBIC ACID; AND b) DRYING OF THE PRODUCT OBTAINED UNDER THE DETERMINED CONDITIONS OF TEMPERATURE SUCH AS 40�C, RELATIVE HUMIDITY APPROXIMATE TO 80% AND PRESSURE OF 4KPa AT 7KP. THIS COMPOUND IS CHARACTERIZED BY ITS ANTI-TARGET AND ANTILEUCEMIC PROPERTIES
