“…The mixtures M3 (7-8) and M4 (10-11) showed NMR data identical to those reported for sitosterol (7), stigmasterol (8), β-sitosteryl-3-O-β-D-glucopyranoside (10) and stigmasteryl-3-O-β-D-glucopyranoside (11) (Kojima et al, 1990;Chaves et al, 2010).…”

Abstract:The chromatography fractionation of the hexane, chloroform and ethyl acetate extracts from the leaves and stems of Rourea doniana Baker, Connaraceae, resulted in the isolation of five triterpenes (lupeol, lupenone, α-amyrenone, β-amyrenone, and taraxerol), a flavonol (7,4'-dimethylkaempferol), a coumarin (scopoletin) and four phytosteroids (β-sitosterol, stigmasterol, β-sitosteryl-3-O-β-D-glucopyranoside and stigmasteryl-3-O-β-D-glucopyranoside). All compounds are being for the first time in this species and all triterpenes and the flavonol are being described for the first time in the family Connaraceae. These compounds were identified on basis of their IR and NMR ( 1 H, 13 C, DEPT, HSQC, HMBC, and NOESY) spectral data and by comparison with literature data.

“…The mixture of fatty acids was methylated with excess trimethylsilyl-diazomethane (TMSCHN 2 ) and characterized by GC-MS to be mainly composed of methyl myristate (3.3%), methyl palmitate (62.2%), methyl oleate (20.1%), methyl stearate (9.8%), and methyl linoleate (4.5%). On the other hand, the second mixture was further purified by silica column chromatography and identified as consisting of butyrospermol [14] and β -sitosterol [15]. The negative ESI-MS spectrum of the whole mixture showed a series of molecular ion (Fig.…”

A mixture of four new butyrospermol and two known β -sitosterol fatty acid esters, was obtained from the fruit of a Chinese mangrove Xylocarpus granatum. The structures of these compounds were established on the basis of spectroscopic data and chemical means. The butyrospermol fatty acid esters were characterized as mainly comprising butyrospermol 3β -O-palmitate (1), butyrospermol 3β -O-oleate (2), butyrospermol 3β -O-stearate (3) and butyrospermol 3β -O-linoleate (4). The β -sitosterol fatty acid esters were identified as mainly containing β -sitosterol 3β -O-myristate and β -sitosterol 3β -O-oleate.

“…These observations further confirm the C-3-O-glycosyl moiety in the flavone and allowed to identify 7 as rutin. 22,23 The known natural steroid 8, its glycoside 9 and the terpenoids 10-14 were identified by analysis of their spectral data including the acetyl derivative 9a and comparison with literature values, mainly 13 C NMR chemical shifts described for sitosterol (8), 24,25 sitosterol-3O-β-D-glycopiranoside (9) 26 and the mixture of lupeol, α-amyrin and β-amyrin (12-14), friedelin (10) and friedelinol (11) .…”
