abstract = "Geranium robertianum L. (Geraniaceae) has been traditionally used to treat a
range of ailments, including high blood pressure Recent in vitro studies have
shown that some traditional usages, such as antimicrobials, were scientifically
confirmed. Although the phytoconstituents of this plant species have been
extensively studied, some plant parts used in traditional medicine, such as
flowers, have not yet been chemically characterized. Given that the inhibition
of the angiotensin converting enzyme (ACE) is one of the most significant
mechanisms for decreasing blood pressure, we undertook this investigation to
find scientific support for G. robertianum anti-hypertensive traditional use.
Acetone was used to extract plant material since prior research revealed that it
had the highest total phenol and total flavonoid levels, which are considered to
be the primary sources of bioactive chemicals. The chemical composition of
G. robertianum collected in R. Srpska was determined using the LC MS
method, and the ACE inhibitory activity of acetone extract was measured
through the enzymatically cleaved 3-hydroxybutyric acid from 3-
hydryoxybutyryl-gly-gly-gly. Geraniin, a hydrolysable tannin with a Mr of
952.6, was the most abundant single chemical found in the extract. Derivatives
of galic and ellagic acids, as well as flavonoids like kaempferol and quercetine,
a were also present in significant amounts. G. robertianum acetonic floral
extract has been shown to be an effective natural ACE inhibitor with an IC50
of 22.14 μg/mL. To the best of our knowledge, this is the first report on the
chemical composition of G. robertianum floral acetonic extract and its ACE
inhibitory activity.",
