Abstract
Official abstract text for this publication.
A heptane composition obtained from a plant source is described, wherein the plant source comprises Commiphora wildii and wherein the heptane composition is obtained by a process of extraction comprising hydrodistilling or steam distilling a resin of Commiphora wildii to obtain an essential oil. A method of using the heptane composition as a solvent for extracting one or more natural products is also described.
First claim
Opening claim text (preview).
The invention claimed is: 1. A heptane composition obtained from a plant source, wherein the plant source comprises Commiphora wildii , wherein the heptane composition is prepared by a process of extraction comprising hydrodistilling or steam distilling a resin of Commiphora wildii to obtain an essential oil, wherein the process further comprises physically purifying the heptane composition by fractional distillation or by molecular distillation; and wherein the purified heptane composition comprises at least 99.3% heptane, 0.3% alpha-pinene, and 0.1% beta-pinene. 2. The heptane composition as claimed in claim 1 , wherein a content of linear isomer n-heptane is above 99.0%. 3. The heptane composition as claimed in claim 1 , wherein the essential oil is obtained in an amount of about 5.5% based on a fresh weight of resin. 4. The heptane composition as claimed in claim 1 , wherein the process further comprises collecting resin from plants of a cultivated type or wild type. 5. The heptane composition as claimed in claim 1 , wherein the process further comprises collecting resin from a whole plant. 6. A method of using the heptane composition as claimed in claim 1 , the method comprising extracting one or more natural products from a second plant source with the heptane composition of claim 1 as a solvent. 7. The method as claimed in claim 6 , wherein the natural product comprises rose, jasmine, lily, violet, mimosa , tuberose or any other plant useful in perfumery, cosmetics and food flavoring.
