Chemical constituents of essential oils from Solanum torvum leaves, stems, fruits, and roots

Volatile Constituents from the Leaves, Fruits (Berries), Stems and Roots of Solanum xanthocarpum from Nepal

“…Solavetivone (22.9%), palmitic acid (21.0%), and linoleic acid (8.2%) were the major components in the root essential oil, while the stem oil was dominated by palmitic acid (28.9%), heptacosane (12.8%) and linoleic acid (10.1%). In marked contrast, dillapiole (48.0%), cyclocolorenone (12.6%) and nerol (12.0%) were the major components in the root oil of S. torvum, while β-vetivene (55.4%) and 1,10-di-epi-cubenol (25.6%) dominated the stem oil of S. torvum[27]. There do not seem to be any common phytochemical taxonomic markers in the essential oils of Solanum spp; the chemical diversity observed in this genus mirrors the taxonomic diversity.Solanum xanthocarpum Schrad.…”

“…S. erianthum leaves were rich in monoterpenes (68.2%) including β-pinene, α-phellandrene, p-cymene, and αterpinolene, but were devoid of either fatty acids or aliphatic hydrocarbons [28]. In sharp contrast, headspace volatiles collected from growing S. tuberosum were dominated by the sesquiterpenoids (E)-caryophyllene, germacrene D, and germacrene D-4-ol [30], while the leaf oil of S. torvum was rich in (E)-asarone (36.4%) and (Z)-asarone (30.1%) [27]. fruit leaf root stem 1071 1-Octanol ---------tr 1098 Linalool ---------tr 1103 Nonanal 0.2 ------tr 1110 2-Phenylethyl alcohol ---------tr 1115 (E) Methyl eugenol 0.5 Pentadecanoic acid ---…”

“…The fruit oil of S. aculeastrum was composed largely of long-chain alkanes [26]. The fruits of S. torvum were dominated by dillapiole (55.3%), methyl salicylate (19.5%), and santalone (16.1%) [27], none of which were detected in S. xanthocarpum fruits. The fruit oils of both S. macranthum and S. erianthum were dominated by the sesquiterpenoids (E)-caryophyllene (17.8% and 10.9%, respectively), α-humulene (36.0% and 23.1%, respectively), caryophyllene oxide (5.0% and 16.5%, respectively), and humulene epoxide II (5.5% and 20.0%, respectively), in addition to methyl salicylate (8.1% and 11.8%, respectively) [28].…”
