This plant has therapeutic properties in its different parts. GC-MS analysis revealed the presence of many phytochemicals in root methanolic extracts involving 14 active compounds. It was found that a high percent area is 2-furancarboxylaldehyde (50.07%). Ethyl aldehyde had the lowest area (0.49%). In contrast, ethanolic extract of root contained 19 active compounds as GC-MS isolated and characterized. The technique confirmed that 6-octadecenoic acid was the highest compound (59.43%), while N-sulfinyl butylamine has rarely been detected in plant extracts (0.12%). Many other phytochemicals were also detected. Similarly, methanol extract for stem branches included three active compounds. A 5-hydroxymethylfufural was the most abundant (63.06%), while 2-acetyl-2H-tetrazole possessed the lowest area (9.70%). Ethanol extract contained six isolated active compounds. Few major compounds were found with a high percent peak area in branches by ethanol extract including 5-hydroxymethylfurfural (55.81%), whereas, the lowest one was hydrazinecarboxaldehyde (0.49%). https://cjes.guilan.ac.ir/article_7465_31e004c0303060adb76e13a135bfe7a3.pdf
