Standardization of protocol for in vitro propagation of an endangered medicinal plant Rauwolfia serpentina Benth.
The present investigation was carried out with a view to standardize an in vitro culture technique for mass propagation of an endangered medicinal plant Rauwolfia serpentinaBenth. Shoot tip was used as explant for initial culture. The explants were cultured on MS (Murashige and Skoog, 1962) medium supplemented with different concentration and combination of NAA and BA for primary shoot proliferation. The...

Botanical identification and ethno-medicinal uses of some underground part of medicinal plants collected and traded in Marrakech region
To establish a standardized and reliable data basis on the medicinal species used for their underground organs, many specimens were collected in the Marrakech region in collaboration with collectors and herbalists. The local ethno-medicinal uses of these medicinal underground organs were also recorded. The result showed that forty one medicinal species are exploited for their underground organs to treat a variety of...

Optimization of extraction methods with alkali and determination of stachyose, sucrose, and raffinose in fresh rehmannia (Rehmannia glutinosa Libosch) using high-performance liquid chromatography with evaporative light scattering detection
A high-performance liquid chromatography (HPLC) method with evaporative light scattering detection (ELSD) was used to determine the stachyose, sucrose, and raffinose in Rehmannia glutinosa Libosch simultaneously. Carbohydrates were separated on an XBridgeTM Amide column using a mixture solvent of acetonitrile: water (70:30, v/v) as mobile phase. Four different methods for the extraction and purification...

Polyphenol compounds with anti-carcinogenic qualities: Effects of quercetin (flavonol), chrysin (flavon), kaempferol (flavanol), naringenin (flavanon) and hesperidin (flavanoid) on in vitro breast cancer
Epidemiological, clinical or animal studies have suggested an inverse association between the consumption of polyphenol and polyphenol-rich foods or beverages and the prevention of diseases. Previously, the following effects have been shown on flavonoids from the black elderberry, Sambucus nigra, on cells. Quercetin: apoptosis induction, antioxidant, protein kinase inhibitor, interaction with type II...

Phytochemical composition, antifungal, antiaflatoxigenic, antioxidant, and anticancer activities of Glycyrrhiza glabra L. and Matricaria chamomilla L. essential oils
The present study was undertaken to investigate the antifungal, antiaflatoxigenic, antioxidant, and anticancer activities of Glycyrrhiza glabra L. and Matricaria chamomilla L.essential oils and their phytochemical composition. The essential oils were obtained by hydrodistillation and their phytochemical composition was determined throughout gas chromatography-mas spectrometry (GC-MS) analysis. Both...

Two new pro-apoptotic glucopyranosides from Tulbaghia violacea
Tulbaghia violacea is a widely known anticancer herb used as traditional medicine in the Southern African region. However, the identities of the chemical compounds responsible for the medicinal properties are still at large. Isolation of the pro-apoptotic compounds from T. violacea was carried out using apoptosis induction-guided fractionation. The chemical structures of the pro-apoptotic molecules...

Antibacterial and antioxidant activities of seedlings of Rumex vesicarius L. (Polygonaceae)
The present work has been carried out to investigate both the antibacterial and antioxidant activities of seedlings grown in vitro and in vivo. Only ethanol extract of in vitro germinated seedlings on solidified Murashige and Skoog (MS) hormone free medium, had antibacterial activity. Activity was high in case of Pseudomonas aeruginosa, Escherichia coli and Streptococcus pneumoniae (inhibition zones = 55.00 ±...
