Inhibitory Effects of Cissus quadrangularis L. Derived Components on Lipase, Amylase and α-Glucosidase Activity in vitro
The stems of Cissus quadrangularis L (Vitaceae) have been consumed for centuries throughout Asia and Africa as a culinary vegetable. The aqueous extract of C. quadrangularis stems and leaves contains… Expand
Alkaloids from Balanites aegyptiaca.
High performance liquid chromatographic (HPLC) analysis of a dichloromethane extract of the stem-barks of Balanites aegyptiaca has yielded two known alkaloids, N-trans-feruloyltyramine (1) and… Expand
Secondary metabolite profiling of the model legume Lotus japonicus during its symbiotic interaction with Mesorhizobium loti
Plant secondary metabolites, particularly flavonoids, are key components in the early stages of nitrogen-fixing symbiosis. Despite their importance, the endogenous secondary metabolites involved in… Expand

Pyranoisoflavones from Rinorea welwitschii.
Reversed-phase HPLC analysis of a dichloromethane extract of the stem-barks of Rinorea welwitschii has afforded two pyranoisoflavones, alpinumisoflavone (1) and di-O-methylalpinumisoflavone (2).
The effect of extracts of Irvingia gabonensis (IGOB131) and Dichrostachys glomerata (Dyglomera™) on body weight and lipid parameters of healthy overweight participants
Background: Previous work reported the benefits of extracts of 2 Cameroonian spices – Irvingia gabonensis and Dichrostachys glomerata— on obese people with metabolic syndrome. Considering the… Expand
Synthesis and glycosidase inhibition of the enantiomer of (-)-steviamine, the first example of a new class of indolizidine alkaloid.
(+)-Steviamine, the enantiomer of the natural (-)-steviamine, and its corresponding C5 epimer have been synthesized from the D-ribose-derived cyclic nitrone. (-)-Steviamine was found to be the first… Expand
Looking glass inhibitors: both enantiomeric N-benzyl derivatives of 1,4-dideoxy-1,4-imino-d-lyxitol [a potent competitive inhibitor of α-d-galactosidase] and of 1,4-dideoxy-1,4-imino-l-lyxitol [a…
Abstract Benzhydryl protection by diphenyldiazomethane of an alcohol in enantiomeric base-sensitive ribonolactones allows short efficient syntheses of 1,4-dideoxy-1,4-imino- d -lyxitol (DIL) and of… Expand
