Phytochemical investigation on the stems of Trigonostemonheterophyllus led to the isolation of a new lariciresinol-based lignan glycoside, trigonoheteran (1), together with a known lignan glycoside, aviculin (2). Their structures were elucidated by spectroscopic methods including 1D and 2D NMR (HMQC, 1H-1H COSY, HMBC, and NOESY). © 2014 Taylor & Francis. Source

Phytochemical investigation on the stems of Trigonostemon heterophyllus led to the isolation of a new diterpene, trigonoheterene (1), and a new naphthoquinone, trigonoheterone (2), together with two known compounds, 3,4-seco-sonderianol, (3) and trigonochinene E, (4). Their structures were determined by spectroscopic techniques (UV, IR, MS, 1D and 2D NMR). All compounds were evaluated for cytotoxic activities and antibacterial activities. © 2011 Phytochemical Society of Europe. Published by Elsevier B.V. All rights reserved. Source

A new drimane sesquiterpenoid glycoside, named 7-drimen-3β,11-diol 3-O-β-d-glucopyranoside, was isolated from the 95% EtOH extract of the seeds of Antiaris toxicaria (Pers.) Lesch. The chemical structure was completely elucidated using a combination of 1D and 2D NMR techniques (COSY, HMQC, HMBC, and ROESY) and HR-ESI-MS analysis. The compound showed inhibitory activities toward methicillin-resistant Staphylococcus aureus (MRSA), chronic myelogenous leukemia (K562), and human hepatoma (SMMC-7721) cell lines. © 2011 Taylor & Francis.
