Abstract

Pine resin is obtained from a process of tapping the pine tree (Pinus merkusii Jungh. & de Vriese). After processing, pineresin will produce gondorukem and turpentine. Currently, the utilization of turpentine is mainly for cosmetic, paint, a mixture ofsolvents, antiseptics, and pharmaceuticals. Due to an increase in the added value of the turpentine product, turpentine wassynthesized into borneol. This study aimed to analyze the characteristics of borneol produced from the synthesis of α-pinene usingNaOH and KOH bases. The method was carried out by synthesized α-pinene into borneol through sodium reduction using twoalkali e.i KOH and NaOH. The compounds were characterized by FTIR, NMR and GCMS. The results showed that onFTIR analysis of 12 samples of the borneol synthesized showed fairly similar absorption peaks with peaks appearing on standardborneol FTIRs. The NMR analysis of both HNMR and CNMR, compared with the standard NMR compounds α-pinene,champor and borneol, show that the peaks still show differences. The GCMS result showed the formation of the compound ofborneol compound with the percentage of 0.12 to 2.2% relatives. The type of base and origin of the turpentine used did not showany difference in borneol yield.

Abstract

Dryobalanops aromatica Gaertn is a woody plant that produce oil and crystal which has high economical value. Currently oil and crystals becomes an export commodity for cosmetics and pharmaceuticals purposes. In the community, oil utilization is still limited for simple medication in various minor ailments. Utilization in domestic area is still very limited, thust it is necessary to conduct research that lead to increase additional value of the oil. Utilization as fragrance materials/perfume is expected to increase the added value. Result showed, the preferred perfume formula is that with formulation of Dryobalanops oil (25%), ethanol (75%) and green tea additives as odorant, PG and patchoulioil (0.8%). The characteristics of formula have a soft fragrance level, with sharpness level at rather sharp fragrance. Dryobalanops aromatica oil has borneol as marker compounds. And the other chemical compound, such as Caryophyllene; 3-Cyclohexene-1-methanol, .alpha., .alpha., 4-trimethyl-, (S)- (CAS) p-Menth-1-en-8-ol, (S)-(-)-; 1,4, 7-Cycloundecatriene, 1,5,9,9-tetramethyl-, Z,Z,Z- dan 3-Cyclohexen-1-ol, 4-methyl-1-(1-methylethyl)- (CAS) 4-Terpineol.

Abstract

Research on natural medicinal plants has been growing due to the increasing interest to natural medicinal material that is considered safer than synthetic medicines. In North Sumatera, bark of Cotylelobium sp which is locally known as raru, bas been widely utilized by the local community. The skin bark of this species is commonly used as a mixture of "nira" to produce "tuak" (Batak's traditional alcoholic liquor). In addition, local community has been using this species for traditional bealing as well. This research is to study the potency of raru's skin bark in producing anticocidant using DPHH method. The taxicity activity of the material was also examined using Brine Shrimp Lethality Test (BSLT) method. Results show that the yield extract of Cotylelobium melanocylon Pierre was 30.11% and Cotylelobium lanceolatum Craib was 14.50%. Both extracts contains flavonoid, tanin, saponin, triterpenoid and bidroquinon. The extract of Cotylelobium melanocylon Pierre has antioxidant activity against DPPH radical with value of IG as mus as 108.487 ppm and 77.909 ppm for Cotylelobium lanceolatum Craib. Furthermore, the toxicity of Cotylelobium melanoxylon Pierre was 643.550 ppm and Cotylelobium lanceolatum Craib was 767.191 ppm LC
