TL;DR: Using various chromatographic methods, a new piperidinone alkaloid was isolated from roots of Heracleum dissectum Ledeb and showed significantly inhibitory activity on nitric oxide production in RAW264.7 cells.
Abstract: Using various chromatographic methods, a new piperidinone alkaloid, (3S)-3-{4-[(1E)-3-hydroxyprop-1-en-1-yl]-2-methoxyphenoxy}piperidin-2-one (1), together with 10 known compounds, bergapten (2), xanthotoxol (3), isopimpinellin (4), isobergapten (5), heratomol-6-O-β-d-glucopyranoside (6), scopoletin (7), apterin (8), 3-methoxy-4-β-d-glucopyranosyloxypropiophenone, (praeroside; 9), tachioside (10) and coniferin (11), were isolated from roots of Heracleum dissectum Ledeb. Their structures were elucidated on the basis of physicochemical properties and the detailed interpretation of various spectroscopic data. All the isolated compounds were screened for anti-inflammatory activity in vitro. As the results, compound 1 and 8 showed significantly inhibitory activity on nitric oxide production in RAW264.7 cells.

TL;DR: In this article, a new coumarin diol has been isolated along with three known compounds, 6,8-diprenylumbelliferone, bergapten and isopimpinellin from the chloroform fraction of the leaves of the plant, Chloroxylon swietenia DC.
Abstract: A new coumarin diol has been isolated along with three known coumarin compounds, 6,8-diprenylumbelliferone, bergapten and isopimpinellin from the chloroform fraction of the leaves of the plant, Chloroxylon swietenia DC. The structure of new compound has been established as 6-(2',3'-dihydroxy-3-methylbutyl)-8-prenylumbelliferone based on the spectral (UV, IR, 1 H, 13 C and 2D NMR and mass) data.
