Abstract

A phytochemical investigation on the vines of Tinospora hainanensis led to the isolation and characterization of a novel lignan (1), nine previously identified lignans (2−10), four known alkaloids (11−14), one cinnamic acid derivative (15), one catechol derivative (16) and one triterpenoid (17). The molecular structures of these constituents were elucidated through the application of an extensive array of spectroscopic methods, and the absolute configuration of 1 was determined by CD method. Notably, compounds 1−7, 9, 14 and 16−17 are identified as new contributions to the Menispermaceae family. Moreover, the current research extends to explore the chemotaxonomic significance of these isolates.

海南Tinospora hainanensis的化学成分及其化学分类意义

通过对Tinospora hainanensis藤本植物的植物化学研究，分离并鉴定了一种新型木脂素(1)、九种已知木脂素（2 ~ 10）、四种已知生物碱（11 ~ 14）、一种肉桂酸衍生物（15）、一种儿茶酚衍生物（16）和一种三萜（17）。通过广泛的光谱方法阐明了这些成分的分子结构，并通过CD法确定了1的绝对构型。值得注意的是，化合物1 ~ 7、9、14和16 ~ 17被鉴定为Menispermaceae科的新成员。此外，目前的研究扩展到探索这些分离物的化学分类意义。

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
