Naucleamide F, a New Monoterpene Indole Alkaloid from Nauclea latifolia.

Abstract: A new monoterpene indole alkaloid, naucleamide F (1), has been isolated from the bark and wood of Nauclea latifolia, and the structure and stereochemistry were elucidated on the basis of the spectral data. Naucleamide F (1) is a new monoterpene indole alkaloid consisting of a tetrahydro-β-carboline ring fused to a pyridone ring, and a 1,3,5-trioxepane ring fused to a dihydropyran ring and a glucose unit.

Selection of protoclones for high yields of indole alkaloids from suspension cultures ofCatharanthus roseus and the qualitative analysis of the compounds by LC-MS

Abstract: To produce economically important indole alkaloids by cell culture, we have selected protoclones ofCatharanthus roseus for high yields of catharanthine and ajmalicine. Protoplasts were enzymatically isolated from suspension-cultured cells. Protoclone VPC-10 produced catharanthine at 5.9 μg/g fresh wt of cells after 10 days of culture, although the original cell line did not produce it at a level detectable by HPLC. Under the same conditions, protoclone VPC-15 produced ajmalicine at 133.6 μg/g, which was about 3 times the productivity of the original cell line. In addition, the indole alkaloids were qualitatively confirmed by LC-MS.
