Characterization and quantification of flavonoids and saponins in adzuki bean (Vigna angularis L.) by HPLC–DAD–ESI–MSn analysis

BACKGROUND Bioactive activities of adzuki bean have been widely reported, however, the phytochemical information of adzuki bean is incomplete. The aim of this study was to characterize and quantify flavonoids and saponins in adzuki bean. High performance liquid chromatography with diode array detection and electro spray ionization-tandem multi-stage mass spectrometry (HPLC-DAD-ESI-MSn) were app...

Draft genome sequence of adzuki bean, Vigna angularis

Adzuki bean (Vigna angularis var. angularis) is a dietary legume crop in East Asia. The presumed progenitor (Vigna angularis var. nipponensis) is widely found in East Asia, suggesting speciation and domestication in these temperate climate regions. Here, we report a draft genome sequence of adzuki bean. The genome assembly covers 75% of the estimated genome and was mapped to 11 pseudo-chromosom...

Isolation and characterization of a cyanidin-catechin pigment from adzuki bean (Vigna angularis).

Adzuki bean is used to prepare many kinds of foods in east Asia, and the seed coat contains water-soluble anthocyanins, catechins, and flavonols. In the present study, ethyl acetate-soluble purplish pigments were isolated from adzuki bean. Pigments of soaked adzuki bean were extracted with 1% HCl in methanol. Ethyl acetate-soluble purple pigments were obtained from the methanol soluble componen...

Stem Rot on Adzuki Bean (Vigna angularis) Caused by Rhizoctonia solani AG 4 HGI in China

During late August and early September 2011, stem rot symptoms were observed on adzuki bean plants (Vigna angularis) growing in fields located in Beijing and Hebei Province, China, respectively. In this study, four isolates were obtained from infected stems of adzuki bean plants. Based on their morphology, and sequence and polymerase chain reaction-restriction fragment length polymorphism (PCR-...
