A new glucosylated cinnamoyl glycerol from aerial parts of Phleum subulatum

摘要

Specimens of Phleum subulatum (Savi) Asch. et Graebn. (Poaceae) were collected at “Castel Volturno” Nature Reserve, a flat coastal area located in the north of Naples (Southern Italy). The area is situated on stabilized dunes of alluvial deposits and loose siliceous-calcareous sand, with a maximum elevation of 9 m above sea level. The climate is typically Mediterranean with precipitation mostly occurring in autumn and winter and with a drought period in summer. The soil is characterized by homogeneous sand with 97.1% sand, 1.25% loam, 1.6% clay, poor in organic matter and nutrients (Rutigliano et al., 2004). Plants of P. subulatum were identified by Dr Assunta Esposito of the Second University of Naples and a voucher specimen (CE0078) has been deposited at the Herbarium of the Dipartimento di Scienze della Vita of the Second University of Naples.
