(20S)-20-Hydroxyvoaluteine Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
This alkaloid occurs in the leaf extract from Tabernaernontana rupicoia Benth. It
is an amorphous substance which cannot be crystallized. The ultraviolet spectrum
has absorption maxima at 228 and 410 mil with a shoulder at 260 mil. It yields
crystalline salts with mineral acids, e.g. the hydrochloride, m.p. 258-9°C (dec.)
and the hydrobromide, m.p. 273-4°C (dec.); [α]
26D - 206° (c 1.21, H20). The
structure has been established from the infrared and NMR spectra.
