Objective: To study the chemical constituents in the dried roots of Saposhnikovia divaricata (Turcz.) Schischk.
Method: The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by IR, UV, MS and NMR evidences.
Result: Two compounds were obtained and identified as nodakenetin (1) and 8-[4-(beta-D-glucopyrano-sy-loxy)-3-methyl-2-buten-1-yl]oxy-5-methoxy-6,7-furanocoumarin (2), respectively.
Conclusion: Compound 2 is a new compound and named sapodivarin.

The study investigated the perceptual interaction between two types of Rose damascena essential oil and two types of Angelica dahurica root essential oil. Using gas chromatography-olfactometer (GC-O) and gas chromatography-mass spectrometer (GC-MS), 24 and 25 aromatic compounds in Rose damascena essential oil and Angelica dahurica root essential oil were identified and quantified, respectively. Based on flavor dilution (FD) values and odor activity values (OAVs), 10 important aroma compounds in Rose damascena essential oil and 6 in Angelica dahurica root essential oil were identified.

The intricate interplay between endophytic microorganisms and plants in the upkeep of biodiversity, the stability of communities, and the operation of ecosystems needs to be more adequately extensive. Although root-associated microbial communities of plants have been revealed for the last decade, the understanding of bacterial and fungal communities associated with the roots of medicinal plants remains elusive. To highlight the importance of Panax ginseng Meyer (PG) in our research, we investigated the root endophytic bacterial and fungal communities of Panax ginseng Meyer (PG), alongside Aralia cordata (AC), Angelica gigas (AG), and Peucedanum japonicum (PJ), utilizing amplicon-based community profiling and advanced bioinformatic methodologies.
