چکیده
Figure 2. The effect of fractions A, B, C, D and E from the EtOAC soluble fraction of the methanolic extract of tuber-barks of C. antiquorum var. esculenta on melanogenesis in melan-a cells. Test samples were tested at three concentrations of 1, 10 and 100 μg/mL. PTU (1-phenyl-2-thiourea) was used as positive control. Test sample and medium were renewed daily. The cell viabilities and the melanin contents of melan-a cells were determined after 3 days. Inhibitory activity of melanogenesis and the effect of cell viability were expressed as a percentage of the control. The data shown represent the means ± SD of three independent experiments performed in duplicate. O O

Cloning, expression, and characterization of soluble starch synthase I cDNA from taro (Colocasia esculenta Var. esculenta).
Soluble starch synthase I (SSSI) cDNA was isolated from taro (Colocasia esculenta var. esculenta) by RT-PCR and rapid amplification of cDNA ends reaction. The transcript of this single-copy gene is 2340 bp and encodes 642 amino acids protein containing a putative transit peptide of 54 residues. Recombinant SSSI protein displayed both primer-dependent and primer-independent activities of starch ...
متن کاملNutritional composition of “gari” analog produced from cassava (Manihot esculenta) and cocoyam (Colocasia esculenta) tuber
Physicochemical properties ofgari analog produced from coprocessing of Cassava (Manihot esculenta Crantz) and Cocoyam (Colocasia esculenta) were investigated. Cassava tuber and cocoyam were coprocessed at different percentages before frying separately. Proximate composition, mineral content, antinutritional factors, and sensory evaluation of various samples were determined. The results showed t...
متن کاملGlycaemic index of selected staples commonly eaten in the Caribbean and the effects of boiling v. crushing.
Integrating information about the glycaemic index (GI) of foods into the Caribbean diet is limited by the lack of data. Therefore, we determined the GI of eight staple foods eaten in the Caribbean and the effect on GI of crushing selected tubers. Groups of eight to ten healthy volunteers participated in three studies at two sites. GI was determined using a standard method with white bread and a...
