Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2013, Volume: 36, Issue:11 To study the chemical constituents from the roots of Ilex pubescens.. The 95% ethanol extract of the plant was separated by silica gel, Sephadex LH-20 and preparative HPLC chromatography. The structures were elucidated based on the physiochemical properties and spectroscopic analysis.. Fifteen compounds were isolated and identified as oleuropein(1), oleoside dimethyl ester(2),8 (Z)-nuezhenide(3),3,4-dicaffeoylquinic acid methyl ester(4),3,4,5-tricaffeoylquinic acid methyl ester (5), isovanillic acid(6), syringic acid(7), 3beta-acetyloleanolic acid (8), 3beta-acetylursolic acid(9), uvaol(10), asiatic acid(11), 2alpha-hydroxyursolic acid(12), oleanolic acid (13), ursolic acid (14), stigmasterol-3-O-beta-D-glucopyranoside (15).. Compounds 2,3,8,9 are obtained from this genus for the first time,compounds 5-7,10-12 are isolated from this plant for the first time.

Triterpenoid content of berries and leaves of bilberry Vaccinium myrtillus from Finland and Poland. Journal of agricultural and food chemistry, 2012, Dec-05, Volume: 60, Issue:48 Triterpenoid compounds found in free and ester forms in extracts of entire fruits and leaves and in fruit and leaf cuticular waxes of bilberry (Vaccinium myrtillus L.) collected in Finland and Poland were identified and quantitated by gas chromatography-mass spectrometry coupled to a flame ionization detector (GC-MS/FID). The main bilberry triterpenoid profile consisted of α- and β-amyrin, α- and β-amyrenone, campesterol, cholesterol, citrostadienol (in berries), cycloartanol, erythrodiol, lupeol, 24-methylenecycloartanol, sitosterol, sitostanol, stigmasterol, stigmasta-3,5-dien-7-one, uvaol, oleanolic and ursolic aldehydes, and oleanolic, ursolic, 2α-hydroxyoleanolic, and 2α-hydroxyursolic acids. Friedelin and D:A-friedooleanan-3β-ol were found only in Finnish plants, whereas D:C-friedours-7-en-3β-ol and taraxasterol were found only in Polish plants. To our knowledge, this is the first thorough description of triterpenoid compounds in this species. The presented results revealed that the triterpenoid profile of bilberry varied considerably between different organs of the plant, regardless of the plant origin, as well as between plant samples obtained from the two geographical locations.

Triterpenoid content of berries and leaves of bilberry Vaccinium myrtillus from Finland and Poland.

Triterpenoid compounds found in free and ester forms in extracts of entire fruits and leaves and in fruit and leaf cuticular waxes of bilberry (Vaccinium myrtillus L.) collected in Finland and Poland were identified and quantitated by gas chromatography-mass spectrometry coupled to a flame ionization detector (GC-MS/FID). The main bilberry triterpenoid profile consisted of α- and β-amyrin, α- and β-amyrenone, campesterol, cholesterol, citrostadienol (in berries), cycloartanol, erythrodiol, lupeol, 24-methylenecycloartanol, sitosterol, sitostanol, stigmasterol, stigmasta-3,5-dien-7-one, uvaol, oleanolic and ursolic aldehydes, and oleanolic, ursolic, 2α-hydroxyoleanolic, and 2α-hydroxyursolic acids. Friedelin and D:A-friedooleanan-3β-ol were found only in Finnish plants, whereas D:C-friedours-7-en-3β-ol and taraxasterol were found only in Polish plants. To our knowledge, this is the first thorough description of triterpenoid compounds in this species.
