Using Radix imperatoriae (the root of masterwort) as an example, we describe an efficient approach for the isolation, identification and evaluation of bioactive plant components on an analytical scale. The extraction of Radix imperatoriae with ethyl acetate was enhanced by the application of ultrasound oscillations. This rhizome extract was applied to three pathogenic bacteria (Bacillus cereus,...

The aim of this study was to determine and compare the anticonvulsant activities of four natural furanocoumarins [bergapten (5-methoxypsoralen), imperatorin (8-isopentenyloxypsoralen), oxypeucedanin (5-epoxy-isopentenyloxypsoralen) and xanthotoxin (8-methoxypsoralen)] in the maximal electroshock-induced seizure test in mice. The anticonvulsant effects of bergapten, imperatorin, oxypeucedanin, a...

The CHCl3 extract of the root of Angelica japonica showed high inhibitory activity against human gastric adenocarcinoma (MK-1) cell growth. From this extract, a new furanocoumarin named japoangelone and four furanocoumarin ethers of falcarindiol, named japoangelols A-D, were isolated together with caffeic acid methyl ester, four polyacetylenic compounds (panaxynol, falcarindiol, 8-O-acetylfalca...

From the methanol extract of the stem bark of Ficus exasperata, a new sphingolipid named Ficusamide, (2S,3S,4R,11E)-2-[(2',3'-dihydroxyhexacosanoylamino)]-11-octadecene-1,3,4-triol (1), along with three known furanocoumarins, (S)-(-) oxypeucedanin hydrate (2), (R)-(+) oxypeucedanin hydrate (3), bergapten (5-methoxypsoralen) and six other known compounds, were isolated. Their structures were cha...

With the objective of determining safety and verifying the traditional uses of the Bhutanese medicinal plant, Pleurospermum amabile Craib & W. W. Smith, we investigated its crude extracts and the isolated phytochemicals for their biological activities. Four phenylpropanoids [(E)-isomyristicin (1), (E)-isoapiol (2), methyl eugenol (3) and (E)-isoelemicin (4)] and six furanocoumarins [psoralen (5...

Two new furanocoumarins, 5-(1",1"-dimethylallyl)-8-methyl psoralen (1) and 2"-O-acetyl oxypeucedanin hydrate-3"-methyl ether (2), were isolated from the root heartwood of Ficus carica Linn. together with three known furanocoumarins, two triterpenoids, two long-chain compounds, and a steroid. Their structures and relative configurations were elucidated by spectroscopic methods (IR, HR-ESI-MS, an...

Aim. Ducrosia anethifolia is used as flavoring additive. There have been little detailed phytochemical reports on this genus and the antidiabetic activity of this plant is not yet evaluated. Method. Structure of compounds was deduced by spectroscopic analyses. Preliminary in vitro evaluation of the antidiabetic activity of crude extract and its furanocoumarins was carried out ( α -amylase, α -g...

Objective(s) As an important class of natural products, coumarins exhibit many biological activities and the diversity of their bioactivity is so huge that the pharmacological promiscuity has been applied on their case. Oxypeucedanine also named as prangolarin is a linear furanocoumarin with an oxygenated prenylated substitution at C-5 of the nucleus. To our knowledge, there are few reports on...

The first phytochemical investigation of the fruits of Angelica lucida has led to the isolation and characterization of five known coumarins (imperatorin, isoimperatorin, heraclenol, oxypeucedanin hydrate and heraclenin). All isolated compounds were identified by means of spectral and literature data. The extracts and the isolated constituents from A. lucida have been also evaluated for their a...
