A study on the micro-propagation and antioxidant activity of Piper longum (an important medicinal plant)
An efficient micro-propagation technique has been developed for cloning Piper longumplantlets by nodal segment multiplication. The result showed that the optimal medium for shoot multiplication was Murashige and Skoog (MS) medium supplemented with 1 mg/L benzyladenine and 1 mg/L indoleacetic acid. The best medium for rooting was in MS medium with 1 mg/L benzyladenine and 0.2 mg/L indoleacetic acid. The present...

Spasmolytic activity of p-menthane esters
The present study aimed to investigate the relationships between the chemical structure and spasmolytic activity of 10 p-menthane monoterpene esters found in aromatic plants. All of the monoterpenes studied had spasmolytic actions in isolated guinea pig ileum. The neo-isopulegyl acetate and the 4-terpinyl acetate were the most potent, while the perillyl acetate was the least potent p-menthane ester. This...

Bioactivity-guided fractionation for antioxidant property of Athyrium multidentatum (Doll) Ching. rhizome
In this paper, methanolic extract of Athyrium multidentatum (Doll) Ching. (AMC) rhizome was fractionated into three fractions (petroleum ether fraction (PEF), ethyl acetate fraction (EAF) and n-butanol fraction (BF)) on the basis of polarity. Each fraction had their antioxidant activities estimated employing various established in vitro systems, including superoxide/hydroxyl radical...

Analysis of the essential oil of Vetiveria nigritana (Benth.) Stapf root growing in Sudan
The volatile oil of the roots of Vetiveria nigritana (Benth.) Stapf was extracted by hydrodistillation for 36 h to yield 1.35%. The physical and chemical properties were determined according to international standards and were not compatible with published data. Analysis of the oil by gas liquid chromatography/mass spectrometry (GLC-MS) technique revealed that the oil was composed of 50 compounds of...
