A new tropane alkaloid, (-)anisodine (I), was isolated from the plant of Anisodus tanguticus. It is a novel ganglio blocking agent. The absolute configuration of (-)anisodinic acid (VII), which is the side chain of (-)anisodine, was determined by chemical correlation with (R) (-)-2-phenyl-1,
OBJECTIVE
To establish an HPLC fingerprint of Anisodus tanguticus root for its quality control.
METHODS
The analysis was carried out on a Ultimate AQ C18 (250 mm x 4.6 mm, 5 μm) column with the gradient elution of acetonitrile and KH2PO4 buffer soution, whose pH was adjusted to 3.0 with phosphoric
Tropane alkaloids (TAs) such as anisodamine, anisodine, hyoscyamine and scopolamine are extensively used in clinical practice as anticholinergic agents. Anisodus acutangulus produces TAs in root tissue, and although several genes involved in scopolamine biosynthesis have been cloned, yet the
BACKGROUND
Tropane alkaloids (TA) including anisodamine, anisodine, hyoscyamine and scopolamine are a group of important anticholinergic drugs with rapidly increasing market demand, so it is significant to improve TA production by biotechnological approaches. Putrescine N-methyltransferase (PMT) was
Tropane alkaloids (TA) including hyoscyamine, anisodamine, scopolamine and anisodine, are used medicinally as anticholinergic agents with increasing market demand, so it is very important to improve TA production by metabolic engineering strategy. Here, we report the simultaneous introduction of
