A new cycloartane-type triterpenoid, named 22-hydroxy-cyclolaudenol (1), together with two known cycloartane-type triterpenoids were isolated from the roots of Dianella ensifolia. Their structures were determined based on spectroscopic methods, including UV, IR, HR-ESI-MS, NMR and X-ray diffraction. Compound 1 displayed cytotoxic effects against cancer cell lines B16-F10, A549 and MDA-MB-231.

is a species from the genus (Meliaceae) and the chemical constituent has not been widely explored. A new cycloartane-type triterpenoid, pachyphyllanone (), along with four known compounds (-) were isolated from Miq. Furthermore, the structure of the new compound was elucidated by the interpretation of spectroscopic data, including 1D and 2D-NMR, as well as ECD and NMR calculations (DP4+ analysis).

, a significant forage plant cultivated in arid regions of northwest China, remains underexplored for its triterpenoid saponins and medicinal properties compared to the extensively studied . To explore the phytochemical profile of for its potential application in the medical field, we employed ultra-pressure liquid chromatography coupled with a tandem mass spectrometry-based method to identify cycloartane-type triterpenes. Eventually, five new cycloartane-type triterpenoids, adsurgosides A - D ( 1 - 4: ) and 3-methyl-3,4-seco-cyclostellanol (5: ), together with two known analogs, cycloastragenol (6: ) and cyclopycanthogenin (7: ), were isolated from the roots of .

Nine previously undescribed (1-9) and seven known (10-16) cycloartane-type triterpenoids were isolated and characterized from Combretum quadrangulare Kurz using physicochemical and spectroscopic methods. The absolute configurations of these compounds were determined through modified Mosher's method and quantum chemical calculation of electronic circular dichroism (ECD) and vibrational circular dichroism (VCD) spectra. Their inhibitory activities against PCSK9 secretion were assessed, and a plausible structure-activity relationship was delineated.

is a widespread genus comprising approximately 3500 species, both annual and perennial, found across Asia, Europe, Africa, and the Americas. In Turkey, it is represented by 63 sections and 485 taxa with a high endemism ratio (51%). In traditional medicine, the roots of various species represent very old and well-known drugs used for antiperspirant, diuretic, and tonic purposes, as well as for the treatment of nephritis, diabetes, leukemia, and uterine cancer.

Article Synopsis
- - The study discovered a new compound, astracondensatol A, alongside six other known derivatives from the methanol extract of roots, focusing on tetrahydropyran cycloartane-type triterpenoids.
- - Researchers used 1D and 2D-NMR spectroscopy and mass spectrometry to determine the structures of these compounds, uncovering anomalies in carbon shifts that led to a revision of the absolute configurations.
- - X-ray crystallography confirmed the absolute configuration of the new compound, highlighting that previous misassignments at C-24 may have resulted from ambiguous data and publication biases.
