Three new compounds (-), together with six known compounds (-), were isolated from the ethyl acetate fraction of ethanol extract of the aerial parts of Burm.f. All of these known compounds were isolated from the plant for the first time. Their structures including absolute configurations were elucidated on the basis of HR-ESI-MS, NMR spectroscopic analyses, single crystal X-ray diffraction and comparison with the literatures. Compounds - were tested for their antioxidant and anti-inflammatory activities. Compounds and showed the antioxidant activities with IC values of 28.61 ± 1.56 and 22.55 ± 1.38 M, respectively. Compounds and showed anti-inflammatory activity in LPS-induced RAW 264.7 macrophages with the IC values of 20.95 ± 1.11 and 16.50 ± 1.04 M, respectively.

The aim was to investigate the morphological, photosynthetic, and hydraulic physiological characteristics of different genotypes of under controlled cultivation conditions. Growth, conductance, and hydraulic conductivity of the root system of 16 genotypes were evaluated in Experiment 1 (November 2013). In Experiment 2 (December 2014), in addition to the previous characteristics, gas exchange, photochemical efficiency, leaf water potential, and leaf hydraulic conductivity were investigated in five genotypes.
