Description:
Background: Ferulago angulata (Schltdl.) Boiss. is a herbaceous perennial plant distributed in
Iran, Turkey and Iraq. The aromatic aerial parts of this plant are commonly used as antiseptic,
sedative, wound healing, analgesic and food additive.
Methods: Column chromatography on silica gel (normal phase and RP-18) and Sephadex
LH-20, along with recrystallization method were applied to isolation of the phytochemicals
extracted from F. angulata fruits. The structures of the isolated compounds were characterized
by 1
H-NMR and 13C-NMR spectral analysis. Chemical composition of the fruits essential oil
obtained by hydrodistillation (HD) and steam distillation (SD) methods were also analyzed
using GC-MS technique.
Results: Six coumarin derivatives; suberosin (1), isoimperatorin (2), imperatorin (3),
bergapten (4), tamarin (5) and suberenol (6), a monoterpene glycoside; verbenone-5-O-?-Dglucopyranoside (7), together with five flavonol-3-O-glycosides; isorhamnetin-3-O-rutinoside
(narcissin) (8), kaempferol-3-O-rutinoside (nicotiflorin) (9), quercetin-3-O-rutinoside (rutin)
(10), isorhamnetin-3-O-?-D-glucuronide (11), isorhamnetin-3-O-?-D-glucopyranoside (12)
were isolated from F. angulata fruits. Essential oil extraction using HD and SD methods afforded
colorless oils in 4.1 and 1.8% (v/w) yields, respectively. A total of 28 compounds were identified
in essential oils, of which (Z)-?-ocimene (HD; 48.97%, SD; 50.02%), ?-pinene (HD; 21.32%, SD;
23.06%) and allo-ocimene (HD; 6.98%, SD; 5.61%) were the main compounds.
Conclusion: This study introduces F. angulata fruits as a new source of coumarin derivatives
and flavonoid glycosides. The presence of these compounds with known biological properties
provides more medicinal potentials for the fruits of F. angulata. The present study also reports
hydrodistillation, as an efficient method for extraction of essential oil from these aromatic fruits.
