For clarifying the phylogenetic diversity of fifteen species of the subgenus Ceratotropis, including seven wild and three cultivated Vigna species collected from Myanmar, sequence variations in three trnT-F non-coding regions of the chloroplast genome were analyzed. The Myanmar materials were clustered into two well differentiated groups, the azuki bean group and the mung bean group. Six Myanmar species were clustered into the azuki bean group, and four species into the mung bean group. The azuki bean group consisted of three subclades: angularis-nepalensis subclade, minima subclade and riukiuensis-nakashimae-umbellatahirtella-exilis subclade. No clear lineage differentiation was found among the three races of V. angularis and V. nepalensis. An accession from Myanmar, which showed similar morphological features to those of wild azuki bean, shared a 51-bp deletion with V. angularis and V. nepalensis. Three V. minima accessions showed a distinct clade. V. riukiuensis showed a nested relationship with V. nakashimae sistered to V. hirtella, V. umbellata and V. exilis. The mung bean group consisted of five radiated subclades. In the mung bean group, V. trinervia from Myanmar was clustered with V. reflexo-pilosa, and wild mung bean accessions with their cultivated accessions. A high level of substitution, indel and microsatellite variations in the trnT-F sequences indicated that mung bean (V. radiata) and black gram (V. mungo) are phylogenetically well differentiated in the mung bean group. Myanmar is considered to be an area overlapping two major groups of the subgenus Ceratotropis.

“…Adzuki bean (Vigna angularis) is a major pulse crop in the subgenus Ceratotropis and are mainly produced and consumed in Asia (Siriwardhane, Egawa, & Tomooka, 1992). Recently, adzuki beans have attracted attention for their considerable health benefits and functional components.…”

Seventeen Chinese adzuki (Vignaumbellata.) bean varieties were collected and milled. The nutritional compositions including starch, fat, protein and phytochemicals were analyzed. Results obtained showed that these adzuki beans have a high content of resistant starch which accounts for about 23.57% of total starch, and have suitable amino acid constitutions. Palmitic acid (27.68%), linoleic acid (33.11%) and linolenic acid (26.61%) were the dominant fatty acids. Besides, four bound phenolic acid and two free phenolic acids were identified by HPLC. The antioxidant activity of 70% ethanol extracts and α-glucosidase inhibition activity of water extracts were evaluated. All the adzuki beans possessed strong ABTS .+ free-radical-scavenging capacity and α-glucosidase inhibition activity. Significant positive correlations (P < .01) of the antioxidant activity with total phenolic acids, total flavonoids and free caffeic acid contents were observed. These results are anticipated to providing useful information on the development of adzuki bean-based functional food.

Structure of two purple pigments, catechinopyranocyanidins A and B from the seed-coat of the small red bean, Vigna angularis

The small red bean, Vigna angularis, is primarily used to produce the “an-paste” component of Japanese sweets. Through the manufacturing process, the red seed-coat pigment is transferred to the colorless “an-particles”, imparting a purple color. However, the major pigment in the seed coat has not yet been identified, although it is historically presumed to be an anthocyanin. Here, we report the isolation and structural determination of two hydrophobic purple pigments in the seed coat via instrumental analysis and derivatization. The new pigments, catechinopyranocyanidins A and B, contain a novel pyranoanthocyanidin skeleton condensed with a catechin and cyanidin ring system, and no sugar moieties. Catechinopyranocyanidins A and B are diastereomers with a different configuration at the catechin moiety, and both are purple in color in strongly acidic-to-neutral media. Catechinopyranocyanidins A and B are very stable under dark conditions, but, labile to light and decompose to colorless compounds. Thus, these pigments exhibit quite different chemical properties compared to simple anthocyanidins.
