Abstract

To explore the chemical constituents of Selaginella tamariscina and their effects on cancer cells, this study employed multiple chromatographic techniques including polyamide, silica gel, and semi-preparative High-performance liquid chromatography for compound isolation. The structures of the compounds were elucidated based on physicochemical properties and spectroscopic data. A pair of epimeric lignan glycosides, 7'R-tamariscinol U 4-O-β-d-glucopyranoside (1), 7'S-tamariscinol U 4-O-β-d-glucopyranoside (2) were obtained, along with two known compounds 3,5,7-trimethoxyflavone-4'-O-β-d-glucopyranoside (3) and selapeptin B (4). 1 and 2 are new, while the spectral data of 3 and 4 in methanol-d₄ are reported for the first time.

期刊介绍： The Journal of Asian Natural Products Research (JANPR) publishes chemical and pharmaceutical studies in the English language in the field of natural product research on Asian ethnic medicine. The journal publishes work from scientists in Asian countries, e.g. China, Japan, Korea and India, including contributions from other countries concerning natural products of Asia. The journal is chemistry-orientated. Major fields covered are: isolation and structural elucidation of natural constituents (including those for non-medical uses), synthesis and transformation (including biosynthesis and biotransformation) of natural products, pharmacognosy, and allied topics. Biological evaluation of crude extracts are acceptable only as supporting data for pure isolates with well-characterized structures. All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymized refereeing by at least two expert referees.
