Septerine and septefine — new alkaloids ofAconitum septentrionale

From the roots of Aconitum septentrionale Koelle we have isolated the new nor- and bisnorditerpenoid alkaloids septerine (1) and septefine (2), each containing a N-methylanthraniloyl fragment. Their structures have been established from IR-, mass-, and PMR-spectral results. Structure (1) for septerine has been confirmed by the formation of lycoctonine on its hydrolysis.Institute of the Chemistry of Plant Substances, Academy of Sciences of the Republic of Uzbekistan, Tashkent, fax (3712) 89 14 75.

Transferase and hydrolase activities of phospholipase D from the roots ofAconitum arcuatum

The phospholipase D fromAconitum arcuatum has been studied. The optimum pH values have been determined: 6.3 for the hydrolase activity and 8.0 for the transferase activity. Calcium ions activate the phospholipase D: the hydrolase activity most strongly at 8 and 30 µmole and the transferase activity at 30 µmole. The hydrolase activity of the phospholipase D is not activated by low concentrations of sodium dodecyl sulfate, while the transferase activity is activated to a considerable degree. The results obtained are compared with those on the activation of cabbage phospholipase D.     

Isolation of lappaconitine from Aconitum septentrionale roots by adsorption

Extracts of Aconitum septentrionale Koelle roots obtained using chloroform, isopropanol, and ethanol were purified using chloroform and basic γ-Al₂O₃. Ballast materials were selectively adsorbed by γ-Al₂O₃, increasing the mass fraction of lappaconitine in the extract. The ethanol extract was purified most. The degree of lappaconitine extraction by chloroform was unaffected by the presence of γ-Al₂O₃. However, the mass fraction in the extract and lappaconitine extraction from Aconitum septentrionale were increased more than twice. __________ Translated from Khimiya Prirodnykh Soedinenii, No. 3, pp. 274–276, May–June, 2006.     

GC-MS analysis of total diterpene alkaloids from roots of Aconitum septentrionale

For the first time, using a MS 25RF chromato-mass spectrometer with a Carlo Erba 5160 chromatograph and a packed column, the possibility of the partial separation of the mixture of diterpene alkaloids of various types from the roots ofAconitum septentrionale has been shown. From their chromatographic parameters and mass-spectral characteristics 18 bases have been detected, including a new one with M⁺ 407 which was probably deoxydelcorine, while 6-O-methyldelcorine and 6-O-methyleldelidine have been found in plants for the first time.Institute of the Chemistry of Plant Substances, Uzbek SSR Academy of Sciences, Tashkent.

Lipids of the tuberous roots ofMandragora turcomanica

The lipids of the tuberous roots ofMandragora turcomanica Mizger (fam. Solanaceae) have been characterized for the first time. By using CC, TLC, Ag⁺-TLC, UV and IR spectroscopies and mass spectrometry, 20 classes of lipids and lipophilic substances have been characterized. The main components of the acyl-containing lipids that were isolated were found to be triacylglycerols and glycolipids, and among the lipophilic compounds they were alkanols and sterols; in the mixture of fatty acids of the acyl-containing lipids the 18:2, 18:1, and 16:0 acids predominated.

The free, bound, and strongly bound lipids of the crushed seeds, pulp, husks, and meal have been characterized. It has been shown that the bound and strongly-bound lipids differ from the free lipids by a higher level of saturated acids.
