Drevesne smole iz stročnic (Leguminosae- Caesalpinioideae). Kaj je "dizelsko gorivo"?*

Torelli, Niko (author)

Podan je pregled virov, pridobivanja, lastnosti in uporabe drevesnih smol iz družine stročnic (Leguminosae): čitolov balzam, kativov balzam (iz drevesne vrste Prioria copaifera), ilurinski balzam (Paradaniellia oliveri), kopaibov balzam (Copaiferia spp.), južnoameriški kopal (Hymenea courbaril), perujski balzam (Myroxylon balsamum var. pereirae), tolabrankov balzam (Gossweilerodendron balsamiferum), tolujski balzam (Myroxylon balsamum), valabova smola (Eperua falcata), vzhodnoafriški kopal (Trachylobium verrucosum), zahodnoafriški kopali (Guibourtia spp.). Opisana je anatomska osnova drevesnih izločkov (eksudatov(. Drevesa so možen vir energije. Nobelov nagrajenec Melvin Calvin je poročal, da utegne biti copaibov balzam, ki ga pridobivajo z vrtanjem v debla dreves vrst Copaifera langsdorfii in C. multijuga ("dizelska drevesa"), vir dizelskega goriva.

• Title: Tree resins from Leguminosae-Caesalpinioideae. What is a "diesel tree"?

Abstract

An review is given of the sources, harvesting, properties and uses of tree resins from the Leguminosae: cativo balsam (Prioria copaifera), copaiba balsam(Copaifera spp.), East African copal (Trachylobium verrucosum), illurin balsam (Paradaniellia oliveri), South American copal (Hymenea coubaril), tchitola balsam (Oxystigma oxyphyllum), tolabranca balsam (Gossweilerodendron balsamiferum), tolu balsam (Myroxylon balsamum), walaba resin (Eperua falcata), West African copals (Guibourtia spp.). The anatomical basis of tree exudates is described. Trees as a source of energy are considered. Nobel laureate M. Calvin reported that oleoresin copaiba obtained by drilling holes into Copaifera lansdorfii and C. multijuga ("diesel trees" trunks can be a source of diesel fuel.
