A new anti-hypoxia sesquiterpene from the rhizome of Petasites japonicas.

A new sesquiterpene, bakkenolide-Ⅵa (1), was isolated from the rhizome of Petasites japonicas (Sieb. et Zucc.) Maxim.

Effect of repeated retrogradation on structural characteristics and in vitro digestibility of waxy potato starch.

The effects of repeated retrogradation (RR) treatment on the structural characteristics and in vitro digestibility of waxy potato starch were investigated. The cycling times of RR ranging from 1 to 5 were designated as RR-1, RR-2, RR-3, RR-4, and RR-5, respectively. A maximum SDS content (40.

Effect of single-, dual-, and triple-retrogradation treatments on in vitro digestibility and structural characteristics of waxy wheat starch.

The effects of single-retrogradation (SR), dual-retrogradation (DR) and triple-retrogradation (TR) treatments on in vitro digestibility and structural characteristics of waxy wheat starch were investigated. The yield of slowly digestible starch in a DR-treated starch with retrogradation time interval of 48 h reached a maximum of 44.41%.

Effect of temperature-cycled retrogradation on in vitro digestibility and structural characteristics of waxy potato starch.

The effects of temperature-cycled retrogradation treatment on the structural characteristics and in vitro digestibility of waxy potato starch were investigated in this study. The results showed that the maximum yield of slowly digestible starch (SDS) in waxy potato starch reached 38.63% by retrogradation treatment under temperature cycles of 4/25°C for 3 days with an interval of 24h.
