TL;DR: In this article, the identification of the known coumarins isooxypeucedanin (IoP) and xanthotoxin from the leaves and stem of Euxylophora have been carried out.
Abstract: Phytochemical studies of the leaves and stem have led to the identification of the known coumarins isooxypeucedanin, oxypeucedanin hydrate, xanthotoxin, isopimpinellin, 8-methoxymarmesin and marmesin, flavonoids quercetin-3-O-α-L-rhamnopyranoside, myricetin-3-O-α-L-rhamnopyranoside and hesperidin, alkaloids skimmianine and N-methylflindersine and limonoid limonin. The compounds isolated and the chemical profile of Euxylophora obtained from the literature clearly indicate its phytochemical affinities with other Rutoideae species.

TL;DR: In this article, the structures of these compounds were elucidated by UV, IR, 1D and 2D NMR techniques and different fractions from the leaves of C. swietenia were investigated for their tyrosinase inhibition activity.
Abstract: From the leaves of Chloroxylon swietenia DC., 5 known secondary metabolites, namely 6, 8-diprenylumbelliferone (1), bergaptan (2), isopimpinellin (3), tritriacontanol (4), and isoquercetrin (5), were isolated from a folklore medicinal plant. Three compounds were isolated for the first time from this genus. The structures of these compounds were elucidated by UV, IR, 1D and 2D NMR techniques. Different fractions from the leaves of C. swietenia were investigated for their tyrosinase inhibition activity.

TL;DR: Extraction of immature seeds using pyridine gave a much higher yield and a greater variety of furanocoumarins, indicating that the wild parsnip, along with other Apiaceae family plants, may be an important source of bioactive compounds.

TL;DR: Investigation of dynamics of accumulation of five linear furanocoumarins and umbelliferone in stationary liquid cultures of Ruta graveolens ssp.
Abstract: The study was designed to investigate dynamics of accumulation of five linear furanocoumarins and umbelliferone in stationary liquid cultures of Ruta graveolens ssp. divaricata (Tenore) Gams during 6-week growth cycles. The contents of individual metabolites in biomass increased 1.8-3.5 times while their total content rose 2.3 times. Maximum contents of xanthotoxin, bergapten and isopimpinellin (112.3, 76.2 and 84.0mg/100g d.w., respectively) and maximum total content of all metabolites (283.4 mg/100 g d.w.), obtained on 35th culture day, are interesting from practical point of view.
