Abstract

Rattan fruit (jernang) is a non-timber forest product with high economic value.Dracohodin is the major natural compound in dragon's blood resin, which possesses pharmaceutical benefit.Moreover, resins are traditionally obtained by breaking off the layers encasing the rattan fruit (Daemonorps draco), consequently generating large quantities of waste in the form of used rattan fruit (URF). These residue are usually discharged into the environment with no further utility. The objective of this study, therefore, was to extract the resin from URF and test the physical properties, based on SNI Revision 1671-2010. The result showed higher resin yield (4.1%) under the following condition: solvent to solid ratio of 5:1, maceration time of 24 hours, and resin separation with a rotary evaporator at 70 °C for three hours. Besides, the physicochemical evaluation of all parameters, including resin content, water content, ash content and colour were following super quality of SNI Revision, 1671-2010. Also, a comparative test for URF v.s FRF showed a relatively higher yield in FRF, with a difference of only 0.34%,

用过的藤果提取龙血:树脂收率及其物理性质

藤果是一种具有较高经济价值的非用材林产品。龙血素是龙血树脂中的主要天然化合物，具有药用价值。此外，树脂传统上是通过打破缠绕在藤果(Daemonorps draco)上的层来获得的，因此产生大量以使用过的藤果(URF)形式的废物。这些残留物通常被排放到环境中，没有进一步的用途。因此，本研究的目的是根据SNI Revision 1671-2010从URF中提取树脂并测试其物理性质。结果表明:料液比为5:1，浸渍时间为24 h，在70℃旋转蒸发器中分离3 h，树脂得率为4.1%。此外，树脂含量、含水量、灰分含量、颜色等各项参数的理化评价均按照SNI Revision, 1671-2010的优质标准进行。此外，URF与FRF的对比试验表明，FRF的产量相对较高，差异仅为0.34%。
