24-METHYLENE-25-METHYLCYCLOARTANOL AND 24α-ETHYL-5α-CHOLESTAN-3α-OL FROM NEOLITSA SERICEA

A new triterpene alcohol isolated from the stems of Neolitsea sericea was shown to have the structure 24-methylene-25-methylcycloartanol.Moreover, in addition to the common triterpene alcohols and sterols, the following uncommon compounds were isolated from the plant material and were identified: (24E)- and (24Z)-24-ethylidenecycloartanol, (24E)- and (24Z)-24-ethylidene-5α-lanost-8-en-3β-ol, 24 methylene-24(25)-dihydroparkeol, 24-methylene-5α-lanosta-7,9(11)-dien-3β-ol, 24-methylenedammarenol, both C-24 epimers of 14α,24-dimethyl-5α-cholest-9(11)-en-3β-ol, 14α-methyl-24α-ethyl-5α-cholest-9(11)-en-3β-ol, and 24α-ethyl-5α-cholestan-3α-ol. Key words: Neolitsea sericea; Lauraceae; triterpene alcohol; sterol; 24-methylene-25-methylcycloartanol; 24α-ethyl-5α-cholestan-3α-ol.

1H and 13C NMR Assignments for Lanostan-3β-ol Derivatives: Revised Assignments for Lanosterol

1H and 13C NMR assignments are presented for 30 oxygenated lanostane derivatives, including lanosterol, dihydrolanosterol, 7-ketolanosterol, agnosterol, 24,25-epoxylanosterol, 8α,9α-epoxylanostan-3β-ol, three 15-oxygenated derivatives of lanost-7-en-3β-ol, lanostane-3β,7α-diol, lanostane-3B,9α-diol and their acetates.These assignments, which were largely determined by a combination of DEPT, one-bond and long-range 13C-1H chemical shift correlation and lanthanide-induced shift experiments, are not dependent on previously reported assignments, several of which were found to be incorrect. 1H and 13C acetylation shifts for lanostan-3β-ols were sufficiently invariant among the sterols studied that they were useful for assigning carbons in rings A and B.The acetylation shifts reported for lanostan-3β-ols were extended and partially revised.-- Key Words 1H and 13C NMR Oxygenated lanostane derivatives Spectral assignment Lanthanide-induced shifts Long-range HECTOR Acetylation shifts
