Abietane diterpenoids from Cephalotaxus lanceolata.[Pubmed: 28399666]
A new abietane diterpenoid, 12-O-methyl-20-deoxocarnosol-3-one (1), and eight known abietane diterpenoids including 13-abietadien-12-one (2), 5,6-dehydrosugiol (3), sugiol (4), torreyayunnin (5), taxusabietane A (6), hinokiol (7), 3-acetoxyabieta-8,11,13-trien-12-ol (8), and martiusane (9) were obtained from leaves and twigs of Cephalotaxus lanceolata. The structures of isolated compounds (1-9) were determined based on analysis of their spectroscopic data and comparison with those reported in the literature. Compounds 3, 8 and 9 were first isolated from the plants of Cephalotaxus genus.
Five New Alkaloids from Cephalotaxus lanceolata and C. fortunei var. alpina.[Pubmed: 27016921]
Five new alkaloids (1-5) were isolated from the leaves and twigs of Cephalotaxus lanceolata and C. fortunei var. alpina along with 24 known alkaloids. The new structures were elucidated based on spectroscopic data including 1D and 2D NMR, FTIR, UV and MS. These new alkaloids showed no cytotoxicity to HeLa, SGC-7901 gastric cancer, and A-549 lung cancer cell lines.
Alkaloids from Cephalotaxus lanceolata and their cytotoxicities.[Pubmed: 23576344]
A phytochemical investigation of the branches and leaves of Cephalotaxus lanceolata resulted in the isolation of three new cephalotaxus alkaloids, cephalancetines A, B, and D (1, 2, and 4, resp.), together with ten known alkaloids, 3 and 5-13. The structures of the alkaloids were elucidated on the basis of spectroscopic analyses, including 1D- and 2D-NMR, and HR-ESI-MS, and single-crystal X-ray diffraction. All isolated compounds were tested for their cytotoxicities against four human tumor cell lines, A549, HCT116, SK-BR-3, and HepG2. Compounds 12 and 13 showed remarkable activities against A549, HCT116, and HepG2 cell lines.
