Triterpenoids from the stembark ofPyrus Communis
Natural Product Research, 2003Three triterpenoids were isolated from the stem bark of Pyrus communis Linn. and identified as lup-20(29)-ene-3alpha, 27-diol (1), lup-20(29)-ene-3alpha-ol (2) and lup-20(29)-ene-3alpha, 28-diol (3) on the basis of spectral and chemical analysis. The Compound (1) is a novel triterpene, being reported first time by us.

Syrian pear (Pyrus syriaca) as a pollinator for European pear (Pyrus communis) cultivars
Scientia Horticulturae, 2010Abstract In Israel four European pear cultivars are grown: ‘Spadona’ is the main cultivar and ‘Coscia’, ‘Gentile’ and ‘Spadochina’ are its pollinators. However, molecular S -genotyping revealed that ‘Spadona’ is semi-compatible with its three pollinators. This explains, at least in part, the relatively low pear yield in Israel.
