Article Synopsis
- Ethylene influences petal abscission in roses by decreasing the flower's fresh weight and altering the cell structure in the abscission zone (AZ).
- The study investigated the role of reactive oxygen species (ROS) and related gene expressions in petals and AZ cells when treated with different substances (MOCK, ETH, STS, ETH + STS).
- Results indicated that ethylene promotes ROS accumulation by boosting the expression of certain ROS production genes while inhibiting those that manage ROS scavenging, ultimately leading to petal abscission.
Article Synopsis
- The study aimed to identify hypoglycemic components from acid hydrolyzates of total saponins and assess their effectiveness in inhibiting α-glycosidase enzymes and PTP1B.
- Researchers purified eight compounds using silica gel chromatography and identified their structures through NMR, finding that one compound was previously unreported.
- Some isolated compounds showed strong inhibitory effects, particularly one with an IC value significantly lower than the control for α-glucosidase, suggesting potential use as a functional anti-diabetic agent.
