Premna microphylla is a deciduous shrub of Premna in Verbenaceae, which becomes a new material of pectin production. In this study, there were no seed germination while 77.6% suvival rate were reached by using over 2-years branches for cuttage in autumn, winter or early spring. Stem cuttage cultivation was one of the main techniques for high yield. Leaf collecting was in the middle of June, August and October when the pectin content reached the highest.

豆腐柴(Premna microphylla)系马鞭草科豆腐柴属的落叶灌木,是一种新开发的具有较高经济价值的果胶原料。本试验播种种子未发芽,用2年生以上枝条在秋冬或早春扦插繁殖,水培沙固定法成活率达77.6%,是较为理想的育苗方法。采用截干栽培是丰产的主要措施之一。采叶期在6月中旬,8月中下旬和10月中旬,是果胶含量高峰期。

Contents of ginkgolides and bilobalide in more than 200 samples of Ginkgo biloba leaves collected from different growth areas at different tree ages and growth periods have been determined by HPLC methods. The results show that the terpenelactone content in Ginkgo biloba leaves is quite different and is a key factor influencing the quality and production cost of Ginkgo biloba extract. The leaves from young Ginkgo biloba trees (1~6 years old) have higher content of terpenelactone, usually 0.30...

Contents of ginkgolides and bilobalide in more than 200 samples of Ginkgo biloba leaves collected from different growth areas at different tree ages and growth periods have been determined by HPLC methods. The results show that the terpenelactone content in Ginkgo biloba leaves is quite different and is a key factor influencing the quality and production cost of Ginkgo biloba extract. The leaves from young Ginkgo biloba trees (1~6 years old) have higher content of terpenelactone, usually 0.30 %~0.50 % while the content in old tree leaves is usually less than 0.10 %. The superior Ginkgo biloba leaves with terpenelactone content≥0.40 % have been found in all the main growth areas in China, but the best collection time in different areas is different.
