Comparative morphological microscopical and phytochemical studies of root and stem parts of R. cordifolia and R. tinctorum L. (Rubiaceae) have been carried out.

INTRODUCTION Pain is a very well-known signal of ill health and analgesics are the drugs that are used to relieve pain. The main problem with these drugs remains that of side effects. Safer alternatives are natural herbs. Guduchi (Tinospora cordifolia) is one such plant with analgesic potential but few studies are there. OBJECTIVE To evaluate the analgesic activity of commercially available e...

BACKGROUND The invasive weed species Gutenbergia cordifolia has been observed to suppress native plants and to dominate more than half of the entire crater floor (250 km2) in the Ngorongoro Conservation Area (NCA). As this species has been found to be toxic to ruminants it might strongly impact animal populations in this ecologically diverse ecosystem. Hence, a nature-based approach is urgently...

The application of soil mulching is widely used to improve crop productivity within semiarid regions Mediterranean environments. A field study was conducted during two consecutive cycles spearmint (Mentha spicata L.) the rainfed region Southern Italy evaluate effects straw mulch cultivation practices on yields and ecophysiological activities. Four treatments were evaluated: (1) with (RM), (2) w...

Objective(s): The aim of this study was to improve different characteristics including antibacterial, antioxidant and physical properties of nanochitosan film by incorporating Mentha spicata essential oil (EO) and methanolic pomegranate peel and grape seed extracts. Methods: The determination of the chemical composition of M. spicata EO was conducted by means of gas chromatography with ma...

A new anthraquinone, Rubiacordone A (1) (6-acetoxy-1-hydroxy-2-methylanthraquinone-3-O-alpha-L-rhamnopyranoside), was isolated together with the known anthraquinone, 1-acetoxy-6-hydroxy-2-methylanthraquinone-3-O-[alpha-L-rhamnopyranosyl-(1-->2)-beta-D-glucopyranoside] (2), from the dried roots of Rubia cordifolia. Their structures were elucidated on the basis of extensive 1D and 2D-NMR, as well...

The chemical composition of mentha essential oil and mentha extracts obtained at different pressures/temperatures by supercritical fluid extraction (SFE) were studied by GC–MS. The menthol content was also determined spectrophotometrically. The predominant compounds in the essential oil and in the CO2 extract obtained at 100 bar were L-menthon and menthole but at higher pressures (from 150 to 4...
