Objective:
To investigate the chemical constituents from Loquat leaf (Eriobotrya japonica).
Methods:
Compounds were isolated by a combination of silica gel and ODS column chromatographies and preparative TLC and HPLC, their structures were identified by chemical and spectral methods.
Results:
Nine triterpenes were isolated and identified as methyl betuliate (I), oleanolic acid (II), ursolic acid (III), methyl maslinate (IV), methyl corosolate, (methyl 2alpha-3alpha-dihydroxyurs-12-en-28-oate, V), maslinic acid (VI), corosolic acid (VII), tormentic acid (VIII), euscaphic acid (IX) from loquat leaf.
Conclusion:
Compounds I and V are obtained from this plant and Eriobotrya genus for the first time.
