ABSTRACT
The extract of ginkgo leaves showed positive effects on treatments of many diseases, and has been used clinically worldwide. Considering the fact that flavonoids are the main bioactive components in the extract of ginkgo leaves, it is very important to investigate the flavonoid biosynthesis in ginkgo leaves. In this paper, we first reviewed the research progress of flavonoid biosynthesis in different plants, and introduced the flavonoid biosynthesis related genes discovered in ginkgo. Then, several cases of ginkgo researches using high throughput sequencing technology were described in detail. In addition, as an important research area in ginkgo, the changes of flavonoid content and the expression of corresponding genes were discussed. Specifically, our latest results were described. At last, we prospected the development of research area in flavonoid biosynthesis in ginkgo.
ABSTRACT
A key component of Fairy Tofu from leaves of Premna puberula Pamp. was determined by immediate constituent analysis and prescription dismantlement analysis. The results showed that pectin in leaves of P. puberula was the key component as forming Fairy Tofu. It was because the highest component was pectin in Fairy Tofu except water, the pectin extracting directly from the leaves of P. puberula could be formed the jelly like Fairy Tofu, and the leaves which pectin was hydrolyzed by pectinase could not be made Fairy Tofu.
