A coupled LC-MS (liquid-phase chromatography and mass spectrometry) system consisting of a combination of a column of molecularly imprinted polymer (MIP) and a MS detector was used for affinitive separation and on-line identification of the antitumor components, harmine and harmaline, from the
From ancient times, Peganum harmala was claimed to be an important medicinal plant. Its seeds were known to possess hypothermic, and essentially hallucinogenic properties. Various authors have undertaken studies on the antibacterial, antifungal and antiviral effects of Peganum harmala seeds, but
In this study, biological activities of methanolic extracts from Artemisia herba-alba, Ruta chalpensis L. and Peganum harmala L. plants, collected in Centre of Tunisia, were investigated. Results showed an important phenolic composition of Artemisia herba-alba (123.95±4.3g GAE/kg of dry mass). The
A phytochemical study on the methanol extracts from the seeds of Peganum harmala L. led to a new quizonaline alkaloid (S)-vasicinone-1-O-β-d-glucopyranoside (1) and four known ones, (R)-vasicinone-1-O-β-d-glucopyranoside (2), (S)-vasicinone (3), vasicine (4), and deoxyvasicinone (5). Their
BACKGROUND
Progression of cancer cells is completely dependent on its angiogenesis. Inhibition of tumor angiogenesis has shed new light on cancer treatment. As a result, anti-angiogenesis therapy represents one of the most significant advances in clinical oncology. Peganum harmala L.
In this study, we screened 17 medicinal plants for binding activity to G-quadruplex d(TTGGGTT)4 by (1)H NMR spectroscopy and found that the crude extract of Peganum harmala L. seeds showed the most potential binding activity. Subsequently, (1)H NMR- and bioassay-guided isolation of the extract of P.
The present study evaluated the levels of total phenolics, flavonoids, tannins and anthocyanins from Peganum harmala L. seeds and determined their antioxidant, antiplasmodial and anticancer potentials. Antioxidant activity was determined by DPPH and ABTS assays. Extracts of P. harmala seeds from
OBJECTIVE
Peganum harmala (P. harmala), "Espand" in Persian, has small seeds and has been used in traditional medicine as emmenagogue and an abortifacient. It has various pharmacological effects such as antifungal, antibacterial, hypothermic, anticancer, antinociceptive, and reversible monoamine
BACKGROUND
Peganum harmala is used in traditional medicine to treat a number of diseases including cancer. Our preliminary studies show that the alkaloidal extract of PH seed is cytotoxic to several tumor cell lines in vitro and has antitumor effect in a tumor model in vivo. The present
Frangula alnus and Peganum harmala populations growing in Saudi Arabia might be rich sources of natural compounds with important biological activities. A high performance liquid chromatography diode array revealed several polyphenols in the leaf extracts for the first time, including
BACKGROUND
The plants of the genus Peganum have a long history as a Chinese traditional medicine for the treatment of cough, hypertension, diabetes, asthma, jaundice, colic, lumbago, and many other human ailments. Additionally, the plants can be used as an amulet against evil-eye, dye and so on,
