Wound healing activity of acylated iridoid glycosides from Scrophularia nodosa

Abstract

Three acylated iridoid glycosides (E)-6-O-(2", 4"-diacetyl-3" -O-p-methoxycinnamoyl)-alpha-L-rhamnopyranosyl catalpol (scopolioside A) (1), (E)-6-O-(2"-acetyl-3", 4"-di-O,O-p-methoxycinnamoyl)-alpha-L-rhamnopyranosyl catalpol (scrophuloside A(4)) (2) and (E)-6-O-(2",3"-diacetyl-4"-O-p-methoxycinnamoyl)-alpha-L-rhamnopyranosyl catalpol (scrovalentinoside) (3) have been isolated from the dried seed pods of Scrophularia nodosa by HPLC. Their structures were determined by 1D and 2D NMR, UV/Vis and mass spectroscopy and by comparison with published data. All three compounds were shown in vitro to stimulate the growth of human dermal fibroblasts. The effect was negatively dose-dependent for 2 and 3 for which fibroblast growth stimulation was highest at 0.78 microg/mL but was not significantly different from the control at 100 microg/mL. The presence of these compounds in the mature seed pods may explain the ethnobotanical use of this plant in Europe for healing wounds.

“…A wide range of medicinal properties are attributed to Verbascum species (Vijayavitthal et al, 1998;Tuzlaci and Erol, 1999;Konoshima et al, 2000;Sezik et al, 2001;Stevenson et al, 2002;Turker and Camper, 2002;Ahmed et al, 2003;Senatore et al, 2007;Amirnia et al, 2011;Karamian and Ghasemlou, 2013b).…”

Histopathological Evaluation of Burdock (Arctium lappa) Root Hydroalcoholic Extract on Wound Healing

“…These differences were also clearly distinct in microscopic histological figures. In addition, by increasing fibroblasts growth, one will prepare the area for excretion of collagen and as a result for faster wound healing (28). The results of the experiments carried out on the above four groups on 7th day of treatment and at the end of treatment showed that the epider-…”

Effect of Methanolic Extract of Scrophularia subuphylla on Ischemia and Reperfusion-Induced Myocardial Injury

“…9, [16][17][18] S. ningpoensis from this family has been used in treatment of upper respiratory disorders, GI difficulties and fever in Chinese medicine. 19 Furthermore, this species was used in restraining ventricular remodeling in order to ameliorate heart failure with subsequent event of MI.…”
