Physicochemical characterizations of five Dioscorea alata L. starches from China

International Journal of Biological Macromolecules, 2023
D. alata is an important edible and medicinal plant in China. Its tuber is rich in starch but the understanding of the physiochemical properties of D. alata starch is limited. In order to explore the processing and application potential of different D. alata accessions in China, five kinds of D.

Gelling properties of extruded yam ( Dioscorea alata ) starch

Food Chemistry, 1999
Yam (Dioscorea alata) starch was pregelatinized in a single screw extruder. Response Surface Methodology was used to study the effect of extrusion variables: feed moisture (18, 21, 24%), extruder temperature (120, 150, 180°C) and die diameter (3, 4, 5 mm) on cold viscosity, gel-forming capacity and retrogradation of extruded starches.

Occurrence of hexaploid males in Dioscorea alata L.

Euphytica, 1998
In the polyploid species Dioscorea alata, earlier studies have shown a prevalence of higher ploidy levels (2n = 60 and 80) restricted among female clones. Cytological screening of a number of rare flowering collections maintained at the CTCRI revealed the occurrence of hexaploids (2n = 60) among male clones for the first time.

Genetic relationships between Dioscorea alata L. cultivars

Genetic Resources and Crop Evolution, 1998
Isozyme variation was studied to determine genetic relationships among 269 cultivars of Dioscorea alata originating from the South Pacific, Asia, Africa and the Caribbean. Four polymorphic enzyme systems (MDH, PGI, SkDH, 6PGD) revealed 66 isozyme phenotypes, or zymotypes, each uniquely characterized by the presence or absence of 27 electromorphs ...

Floral biology and artificial pollination in Dioscorea alata L.

Euphytica, 1990
Floral biology of Dioscorea alata L. was studied. Anthesis occurred in male flowers by 12.30 h and in female flowers between 13.00 h and 14.30 h. Male flowers remained open for 4–5 hours and female flowers for 9–11 days.

Transformation associated with catecholase in Dioscorea alata during storage

Phytochemistry, 1980
Abstract The Michaelis constant of catecholase in 3 cultivars of Dioscorea alata was determined. Oxidative browning was related to the activity of the enzyme in the yams. Inhibition by cysteine was competitive, while 2-mercaptoethanol caused an uncompetitive type of inhibition.

Phytochemicals Analysis of Water Yam Leaf - Dioscorea Alata

Pharmacy and Drug Development
This research takes a closer look at the chemical makeup of Dioscorea alata (water yam) leaves, using a technique called Gas Chromatography-Mass Spectrometry (GC-MS). While water yam is mostly known and cultivated for its edible tubers, its leaves are often overlooked, even though they hold important medicinal and nutritional value.

Unusually stable monoacylated anthocyanin from purple yam dioscorea alata

Tetrahedron Letters, 1991
Abstract Alatanin C isolated from the tuber of purple yam Dioscorea alata . is the first discovered unusually stable monoacyalated anthocyanin in nuetral aqueous solutions. The stability is ascribed to the intramolecular stacking of sinapic acid and to the chiral self-association of anthocyanidin nuclei.
