Structures were established by analysis of their spectroscopic data (H-1 N... Oleanane-Type Isomeric Triterpenoids from Barringtonia racemosa [作者：Gowri, PM; Radhakrishnan, SVS; Basha, SJ; Sarma, AVS; Rao, JM,期刊：Journal of natural products, 页码：791-795 , 文章类型： Article，,卷期：2009年72-4] Two new isomeric acylated oleanane-type triterpenoids along with three known compounds were isolated from the MeOH extract of the dried fruits of Barringtonia racemosa. On the basis of spectroscopic methods, with special... 5-Bromo-8-methoxy-1-methyl-beta-carboline, an Alkaloid from the New Zealand Marine Bryozoan Pterocella vesiculosa [作者：Till, M; Prinsep, MR,期刊：Journal of natural products, 页码：796-798 , 文章类型： Article，,卷期：2009年72-4] A new alkaloid, 5-bromo-8-methoxy-1-methyl-beta-carboline (1), has been isolated from the New Zealand marine bryozoan Pterocella vesiculosa. Structural elucidation was achieved through NMR spectroscopic and mass spectrom... Cytotoxic Constituents of Chinese Propolis [作者：Sha, N; Guan, SH; Lu, ZQ; Chen, GT; Huang, HL; Xie, FB; Yue, QX; Liu, X; Guo, DA,期刊：Journal of natural products, 页码：799-801 , 文章类型： Article，,卷期：2009年72-4] A pair of new flavanol racemates (1a and 1b) and a new flavanol racemic mixture (2) were isolated from crude propolis from Henan Province, People's Republic of China. Also obtained were nine known compounds, including tw... Structural Reassignment, Absolute Configuration, and Conformation of Hypurticin, a Highly Flexible Polyacyloxy-6-heptenyl-5,6-dihydro-2H-pyran-2-one [作者：Mendoza-Espinoza, JA; Lopez-Vallejo, F; Fragoso-Serrano, M; Pereda-Miranda, R; Cerda-Garcia-Rojas, CM,期刊：Journal of natural products, 页码：700-708 , 文章类型： Article，,卷期：2009年72-4] The structural reassignment, absolute configuration, and conformational behavior of the highly flexible natural product hypurticin (pectinolide E), 6S-[3'S,5'R,6'S-triacetoxy-1Z-heptenyl]-5S-acetoxy-5,6-dihydro-2H-pyran-... Relative Configuration of Natural Products Using NMR Chemical Shifts [作者：Wang, B; Dossey, AT; Walse, SS; Edison, AS; Merz, KM,期刊：Journal of natural products, 页码：709-713 , 文章类型： Article，,卷期：2009年72-4] We have measured and quantum chemically computed NMR chemical shifts for three monoterpene diastereomers produced by the walkingstick, Anisomorpha buprestoides. By taking into account the Boltzmann distribution of confor... Tetranortriterpenoids from the Leaves of Cipadessa cinerascens [作者：Fang, X; Di, YT; Li, CS; Geng, ZL; Zhang, Z; Zhang, Y; Lu, Y; Zheng, QT; Yang, SY; Hao, XJ,期刊：Journal of natural products, 页码：714-718 , 文章类型： Article，,卷期：2009年72-4] Seven known and six new tetranortriterpenoids, cineracipadesins A-F (1-6), were isolated from the leaves of Cipadessa cinerascens.
