ABSTRACT: Hypericum richeri Vill. is a perennial herb belonging to the family Hypericaceae. The distribution area is limited to the mountains of central and south regions of Europa; in Italy this plant is found in the Alps and central Apennines. A few number of studies refer to the biologically active components isolated from H. richeri, but, to the best of our knowledge, this is the first report on the GC-MS detemination of the essental oil composition of this plant. Fresh plant material was subjected to hydrodistillation using a Clevenger-type apparatus for 3 h yielding 0.08% of a yellowish oil. The oil was dried over anhydrous sodium sulphate and stored in sealed vials under refrigeration prior to analysis. The essential oil composition of aerial parts of H. richeri from Italy was analysed by GC and GC-MS. Fifty-one components of the essential oil were identified, representing 98.5 % of the oil. The most abundant components were (Z)--ocimene (19.5% ), n-nonane (13.8% ), -bisabolene (8.7% ), and (E)--ocimene (8.0% ). Other compounds: 2.6-dimethyl heptane, 2-methyl octane, 2-methyl-4-heptanone, -pinene, -pinene, sabinene, -myrcene, limonene, 1.8-cineole, p-cymene, 2,3.5-trimethyl decane, pentyl isovalerate, (E)-thujone, -ylangene, -copaene, linalool, -funebrene, -caryophyllene, terpinen-4-ol, -himachalene, -guaiene, trans-pinocarveol, allo-aromadendrene, germacrene, -terpineol, verbenone, valencene, -muurolene, -cadinene, myrtenol, -calacorene, (Z)-nerolidol, caryophyllene oxide, humulene epoxide-l, (E)-nerolidol, viridiflorol, globulol epi--cadinol, spathulenol, epi--muurulol, thymol, -cadinol, decanoic acid, dodecanoic acid, n-hexacosane, trans-phytol, and hexadecanoic acid.

Abstract

ABSTRACT: Hypericum richeri Vill. is a perennial herb belonging to the family Hypericaceae. The distribution area is limited to the mountains of central and south regions of Europa; in Italy this plant is found in the Alps and central Apennines. A few number of studies refer to the biologically active components isolated from H. richeri, but, to the best of our knowledge, this is the first report on the GC-MS detemination of the essental oil composition of this plant. Fresh plant material was subjected to hydrodistillation using a Clevenger-type apparatus for 3 h yielding 0.08% of a yellowish oil. The oil was dried over anhydrous sodium sulphate and stored in sealed vials under refrigeration prior to analysis. The essential oil composition of aerial parts of H. richeri from Italy was analysed by GC and GC-MS. Fifty-one components of the essential oil were identified, representing 98.5 % of the oil. The most abundant components were (Z)--ocimene (19.5% ), n-nonane (13.8% ), -bisabolene (8.7% ), and (E)--ocimene (8.0% ). Other compounds: 2.6-dimethyl heptane, 2-methyl octane, 2-methyl-4-heptanone, -pinene, -pinene, sabinene, -myrcene, limonene, 1.8-cineole, p-cymene, 2,3.5-trimethyl decane, pentyl isovalerate, (E)-thujone, -ylangene, -copaene, linalool, -funebrene, -caryophyllene, terpinen-4-ol, -himachalene, -guaiene, trans-pinocarveol, allo-aromadendrene, germacrene, -terpineol, verbenone, valencene, -muurolene, -cadinene, myrtenol, -calacorene, (Z)-nerolidol, caryophyllene oxide, humulene epoxide-l, (E)-nerolidol, viridiflorol, globulol epi--cadinol, spathulenol, epi--muurulol, thymol, -cadinol, decanoic acid, dodecanoic acid, n-hexacosane, trans-phytol, and hexadecanoic acid.
