Alkaloids ofGenista libanotica

Abstract

Genista libanotica Boiss. (Fabaceae) is a non-spiny and low shrub (10-20 cm) with compact and rigid branching. The simple leaves are narrowly elliptic and 3-10 x 2-3mm with sparse hairs. Flowers are in short racemes of 2-6. Corolla

Determination of protodioscin in rat plasma by liquid chromatography–tandem mass spectrometry

“…Analytical methods for the determination of protodioscin included a colorimetric method [8], high performance liquid chromatography and evaporative light scattering detection (HPLC-ELSD) [9], precolumn derivatization HPLC [10] and liquid chromatography-mass spectrometry method [11]. However, these methods are less sensitive, selective or involve complicated procedure.…”

LC-MS analysis of daidzein in the Turkish Genista species

“…Adding the species described here raised the number of Turkish Genista species to 14. In our works on Genista species, we previously isolated alkaloids from eleven Genista species, as well as flavonoids from G. aucheri and G. involucrata [18][19][20].…”

Quantification of genistein and daidzein in two endemic Genista species and their antioxidant activity

“…Air-dried and powdered aerial parts of each plant species were extracted following a previously reported method 13,14 for analyzing free and total isoflavones. Each plant was milled homogenously and 1 g was precisely weighed on a digital balancer.…”

“…[8][9][10] In previous studies, the aerial parts of eleven Genista species growing in Turkey were analyzed for their total and free genistein and daidzein contents. 11,12 The highest amount of total and free genistein was found in G. tinctoria, i.e., 1.05 and 0.27 %, respectively, 13 whilst the highest amount of total and free daidzein was found in G. sessilifolia and G. lydia var. antiochia, i.e., 0.0056 and 0.0009 %, respectively.…”
