Identification
Biological Activities
Compounds
Syringa oblata subsp. dilatata, commonly known as Syringa dilatata, serves as a rich natural source of various bioactive compounds. Recent chemical analyses of its flowers have successfully isolated eight new oleoside-type secoiridoids, specifically identified as syringoleosides A-H. In addition to these new discoveries, researchers also identified five previously known secoiridoids within the plant's structure. These specific secoiridoids demonstrate significant biological potential, particularly in their ability to suppress NO production in LPS-induced RAW 264.7 cells. Such findings highlight the importance of studying this native Korean shrub for its potential medicinal and anti-inflammatory properties.
Conditions
Syringa oblata subsp. dilatata, specifically through its flower extracts, contains secoiridoids that inhibit the production of nitric oxide (NO). Researchers isolated eight new oleoside-type secoiridoids, named syringoleosides A-H, from these flowers. Among these compounds, syringoleosides 1, 2, 6, 7, and known compounds 11 and 13 demonstrated significant suppression effects on NO production in LPS-induced RAW 264.7 cells. These specific inhibitory effects were observed with IC50 values ranging from 32.5 ± 9.8 to 65.7 ± 11.0 μM. Notably, these bioactive compounds achieved this reduction in NO production without exhibiting any visible toxicity to the cells.
Preparations
Syringa oblata subsp. dilatata is prepared as flowers to facilitate the isolation of specific chemical compounds. Through repeated column chromatography of these flowers, researchers successfully extracted eight new oleoside-type secoiridoids known as syringoleosides A-H. These floral extracts contain several key compounds, including both newly identified structures and five previously known secoiridoids. The chemical components derived from the flowers, such as compounds 1, 2, 6, 7, 11, and 13, demonstrate a capacity to suppress NO production in LPS-induced RAW 264.7 cells. Ultimately, the major secoiridoid content within the flowers is precisely determined through the application of HPLC analysis.
Parts used
Syringa oblata subsp. dilatata, also known as Syringa dilatata, contains specific bioactive components within its flowers. Recent research has focused on isolating unique secoiridoids, specifically syringoleosides A-H, from these floral structures. Through repeated column chromatography, scientists successfully identified these eight new oleoside-type compounds alongside several known secoiridoids. These chemical constituents demonstrate significant potential due to their ability to suppress NO production in LPS-induced RAW 264.7 cells. Ultimately, the study highlights how the medicinal properties of this native Korean shrub are deeply rooted in its floral chemistry.
