Summary
Researchers isolated a new phenylpropanoid glycoside and three known compounds from Cirsium setosum (Willd.) MB. This study advances our understanding of the plant
Area of Science:
- Phytochemistry
- Natural Product Chemistry
- Pharmacognosy
Background:
- Cirsium setosum (Willd.) MB. is a plant with potential medicinal properties.
- Understanding its chemical constituents is crucial for exploring its therapeutic applications.
Purpose of the Study:
- To isolate and identify chemical constituents from the aerial parts of Cirsium setosum.
- To characterize a novel phenylpropanoid glycoside and known compounds.
Main Methods:
- Extraction of aerial parts using 70% ethanol.
- Isolation of compounds via column chromatography.
- Structure elucidation using spectral and chemical evidence.
Main Results:
- One new phenylpropanoid glycoside, sinapyl alcohol 9-O-(E)-p-coumaroyl-4-O-beta-D-glucopyanoside, was identified.
- Three known compounds: lycoperodine-1, apigenin-7-O-(6"-(E)-p-coumaroyl)-beta-D-galactopyranoside, and quercetin were isolated.
- Lycoperodine-1 was reported from the Cirsium genus for the first time.
- Apigenin-7-O-(6"-(E)-p-coumaroyl)-beta-D-galactopyranoside and quercetin were reported from this plant for the first time.
Conclusions:
- The chemical investigation of Cirsium setosum yielded a new phenylpropanoid glycoside and several known compounds.
- This study expands the phytochemical knowledge of the Cirsium genus and Cirsium setosum specifically.
- The identified compounds may contribute to the pharmacological profile of Cirsium setosum.
