The Influence of Solvent, Host, and Phenological Stage on the Yield, Chemical Composition, and Antidiabetic and Antioxidant Properties of (Sprengel) S. Balle.

was reported to possess many biological properties making it a good candidate for the formulation of a phytomedicine with multiple effects. In this work, we studied some factors likely to modify these therapeutic properties with the aim to contribute to its standardization as an improved traditional medicine. parasitizing and were harvested at three phenological stages (vegetative, flowering, and fruiting stages).

A new alkylbenzoquinone from Gilg. (Myrsinaceae).

A new alkylbenzoquinone named embeliquinone () together with five known compounds, lupeol (), 3--[6'--palmitoyl--d-glucosyl]-spinasta-7,22(23)-diene (), quercetin (), (2,3,4,8)-2-[(2')-2'-hydroxy-heneicosanoylamino]-heneicosane-1,3,4-triol-8-ene (), and -sitosterol-3---d-glucopyranoside () were isolated from the MeOH leaf extract of by using repeated open column chromatography techniques. The structure of the new compound was characterized by analyses of 1D- and 2D-NMR, and MS data. Embeliquinone () had moderate anti-cell proliferation activity against A549 cell line with the IC value of 21.
