Three new hasubanan-type alkaloids, stephalonine Q (1), stephalonine R (2) and stephalonine S (3), together with four known alkaloids, isolonganone (4), eletefine (5), aurantiamide (6), N-cinnamoyltyramine (7), were isolated from the whole plant of . Their structures were identified by NMR, HR-ESI-MS, CD methods and x-ray crystallography, as well as by comparison with the literature data. All isolated compounds were evaluated for their antimicrobial activities against five bacteria .

The light yield of the as-grown PbWO4, annealed PbWO4 and BaF2:PbWO4 crystals were raised by utilizing our improved crystal growth instrument and technique. Their scintillating properties including transmittance, decay time and light yield were studied. Results reveal that the scintillating performances of the crystals were improved evidently by using the crystal annealing technique and the ions doping technique, especially the negative ions doping technique.
