Oncotarget: 6 kinds of plant extracts can delay aging

"Not old spring" may be just a legend, but it has never stopped scientists from looking for the scientific way to obtain "eternal life" In recent years, researchers are interested in rapamycin, metformin and other drugs, mainly because they can effectively prolong life and have the ability to treat diseases However, a recent study shows that the anti-aging ability of these drugs is no longer unique: some plant extracts contain the strongest anti-aging properties known Researchers from Concordia University in Canada conducted more than 10000 screening tests to see if those plant extracts could effectively prolong the survival cycle of yeast You may not imagine that yeast is the most common model organism in the field of life length research, mainly because yeast has similar life span with human cells "In summary, we found that six molecules can effectively delay the life cycle of yeast," said Vladimir titorenko, a researcher from Concordia University The results, published in oncotarget, showed that of the six molecules, willow bark extract had the most significant effect, a phenomenon not previously reported in any magazine In the experiment, willow bark extract can prolong the average life cycle of yeast by 4.75 times and the longest life cycle by 3.69 times If this result can be repeated in other organisms besides yeast, it will be a great discovery In addition, in addition to delaying aging, these compounds can also prevent some diseases, such as cancer Other molecules were extracted from leaf like cohosh, valerian, passionflower, ginkgo and celery The researchers say they will further study the effects of these molecules and their underlying mechanisms in six different projects.
