Pine resins

With very few exceptions, the pine resin acids belong to four basic skeletal classes abietane, pimarane, isopimarane, and labdane (Fig. 7). The acids of the abietane, pimarane and isopimarane series have a isopropyl or methyl/ethyl group in the carbon-13 position and a single carboxyl group in the carbon-18 position, and differ only in the number and location of the carbon-carbon double bonds (the most common have two carbon-carbon double bonds). The acids of labdane series are less common and contain one carboxyl group in the carbon-19 position. [Pg.599]

The structures and nomenclature for the common pine resin acids based on the abietane skeleton (abietic-type acids) are given in Fig. 8. The abietic, neoabietic, palustric and levopimaric acids differ only in tbe location of tbeir two double bonds. All double bonds are endocyclic, except in the neoabietic acid in which one is exocyclic. [Pg.599]

The common pine resin acids based on the pimarane and isopimarane skeletal (pimaric-type acids) are shown in Fig. 9. The pimarane and isopimarane acids series differ only in the methyl group position in the carbon-13 position. Isopimaric and sandaracopimaric acids differ in the location of the carbon-carbon double bond. [Pg.601]

The plants that exude diterpenoid resins belong to the order of conifers. Pine resins (from the Firms genus), Strasburg turpentine (from the Abies genus), Venice turpentine (from Larix decidua) were extracted from Pinaceae. Sandarac, juniper and cypress resins were extracted from trees of the Cupressaceae family Tetraclinis articulata, Juniperus spp. and Cupressus semprevirens, respectively. Moreover, labdanum resin from the Cistaceae family (Cistus spp.) also belongs to the diterpenoid resins. [Pg.14]

Pine resin, namely rosin or colophony, is one of the most widespread diterpenoid resins and has been used for waterproofing, for treating wood and paper, as varnish, as incense and as an ingredient in scented ointments. The main compounds present in fresh Pinaceae resins... [Pg.14]

In both the mass spectra, the simultaneous presence of ion fragments related to 7-oxo-dehydroabietic acid and highly oxidised tricyclic diterpenes demonstrates the higher degree of oxidation of the aged colophony with respect to the fresh pine resin [17 19]. In the mass spectra, the peaks attributed to abietadienic and pimaradienic acids are not evident, indicating their depletion in the course of the resin ageing. [Pg.87]

The first results encouraged the authors to analyse, by headspace SPME, substances mentioned in ancient texts or hieroglyphics as components of embalming fluids [true resins such as mastic, labdanum and pine resin or pine pitch and gum resins such as olibanum, myrrh and galbanum] [27, 28] with the aim of finding characteristic chemical compounds for each type of resin or gum resin. [Pg.262]

Limonene (10) was the major extracted compound from pine resin (Pinus pinea). Since it occurs in other resins or plants it cannot be a biomarker. Longifolene (49), present in a lower amount, is more characteristic of a conifer resin. This sesquiterpene is particularly... [Pg.264]
