Traditional medicine has a key role in health care worldwide. Obtaining scientific information about the
efficacy and safety of the plants is one of the researcher's goals. In this research, the flowering aerial
parts of Rhynchocorys elephas (L.) Griseb (Scrophulariaceae) were collected from Siah Bisheh
(Mazandaran, Iran) in May 2009. Extract was tested for its antibacterial activity using 3 Gram-positive
bacteria strains (Staphylococcus aureus, Staphylococcus epidermidis and Bacillus cereus) and 2 Gram-
negative bacterial strains (Escherichia coli and Salmonella typhi) by cup plate method. Its mutagenic
activity was also investigated using Ames test on Salmonella typhi murium TA100. Here we report for
the first time the activity of R. elephas against S. aureus (MIC =31.25 mg/ml), S. epidermidis (MIC = 31.25
mg/ml), B. cereus (Minimum inhibitory concentration (MIC) = 62.5 mg/ml), E. coli (MIC = 62.5 mg/ml) and
S. typhi (MIC = 62.5 mg/ml). Furthermore the mutagenic potential of R. elephas using Ames test studied
and no mutagenic effects was detected. The results of preliminary phytochemical study showed the
presence of saponins, flavonoids and tannins in the methanolic extract of flowering aerial parts of this
plant.
Key words: Rhynchocorys elephas (L.) Griseb., scrophulariaceae, antibacterial effect, mutagenic activity.
INTRODUCTION
The genus Rhynchocorys (family Scrophulariaceae)
comprises of 5 species which are naturalized in Europe
and some parts of Asia. Two of these species grow wild
in Iran. Rhynchocorys elephas (L.) Griseb. is one of the
species which grow in north of Iran (Saeidi, 2006). There
is no evidence of its traditional use in folk medicine. Since
the literature survey revealed that there is no work on
phytochemical and biological activities of R. elephas, we
were prompted to investigate the antibacterial activity of
methanolic extract of flowering aerial parts of the plant
using the Cup Plate method and its mutagenic effects by

using the Ames mutagenicity test. A preliminary
phytochemical screening, using standard phytochemical
reaction methods, was also done to determine the main
active principles of R. elephas.
MATERIALS AND METHODS
Plant material
The flowering aerial part of R. elephas (L.) Griseb was collected
from Siah-Bisheh (Mazandaran, Iran) in May 2009 and identified by
Dr. G H. Amin at the Pharmacognosy Department, Faculty of
Pharmacy, Tehran University of Medical Sciences, Tehran, Iran. A
voucher specimen (NO. 178) has been deposited in the herbarium
of the Department of Pharmacognosy, Pharmaceutical Sciences
Branch, Azad Islamic University (AIU), Tehran, Iran.
