- ... Rare ginsenoside Rh4 and its aglycone are present in low levels in Panax ginseng. This study focused on achieving ginsenoside Rh4 and its aglycone by microbial transformation of the total saponins of stems and leaves of P. ginseng (TSSLG). A total of 78 fungal strains isolated from the rhizosphere soil of P. ginseng, and one of them, Aspergillus tubingensis, was found to be capable of biotransform ...

- ... A fungal strain, Drechmeria sp., was isolated from the root of Panax notoginseng. Totally, seven new indole diterpenoids, drechmerins A-G (1–7), were isolated from the fermentation broth of Drechmeria sp. together with four known analogues (8–11). Their structures were determined on the basis of 1D and 2D NMR and electronic circular dichroism (ECD) spectroscopic analyses as well as theoretical cal ...
