Variation of Chemical Compounds of Sandalwood Oil From Various Provenances in Indonesia

The quality of sandalwood (Santalum album Linn) oil primarily depends on the compound of two major sesquiterpenes (α-santalol and β-santalol). The aim of this research was to identify variation of chemical compounds of sandalwood oil from various provenances. Fifty four samples from 8 provenances and one land race taken from 13th years old sandalwood planted at Gunungkidul, Yogyakarta Indonesia. Sandalwood powder were obtained by drilling tree at 10 cm above the ground horizontally. The samples were extracted with n-hexane solvent. Identification of chemical compounds of this essential oils were conducted by gas chromatography mass spectrometry analysis (GCMS). The GCMS investigation of sandalwood oils showed that variation compounds both among individual within provenance and between provenances were found in 11 individual from 6 provenances. Compounds such as sesquiterpene, monoterpenes, and others, were found in variying amount. The results showed that α-santalol (32.38-78.29%), β-santalol (5.45%-37.83%) were the major compounds with varying quantities of compounds range of epi-β-santalol (5.97-17.16%), P-Menth-2-En-9-OL-Trans (2.87%-8.53%), and α-sinensal (3.83-9.39%)

Variasi Kandungan Kimia Minyak Cendana (Santalum Album Linn) dari Berbagai Provenans di Indonesia

Kualitas minyak cendana (Santalum album Linn) ditentukan oleh adanya 2 kandungan komponen Sesquiterpene, yakni α-santalol dan β-santalol. Tujuan penelitian ini untuk mengetahui variasi kandungan kimia cendana dari berbagai provenans. Sebanyak 54 sampel dari 8 provenans dan satu ras lahan diambil dari tanaman cendana umur 13 tahun di Hutan Penelitian Watusipat, Gunungkidul, Yogyakarta. Serbuk kayu cendana didapatkan dengan cara mengebor batang cendana setinggi 10 cm di atas permukaan tanah. Serbuk diekstrasi dengan larutan n-hexane untuk mendapatkan larutan minyak. Kandungan kimia larutan cendana dianalisis menggunakan GC-MS (gas chromatography-mass spectrometry). Hasil analisis menunjukkan adanya variasi kandungan kimia baik antar provenans maupun individu dalam provenans yang ditemukan pada 11 sampel dari 6 provenans. Senyawa golongan Sesquiterpene, Monoterpene dan komponen kimia lainnya ditemukan dalam jumlah yang bervariasi. Komponen utama dari hasil pengujian adalah α-santalol (32,38%-78,29%) dan β-santalol (5,45%-37,83%) diikuti oleh epi-β-santalol (5,97%-17,16%), P-Menth-2-En-9-OL-Trans (2,87%-8,53%) dan α-sinensal (3,83%-9,39%)

Craniomaxillofacial Disorders and Solutions in Humans and Animals.

Cross-disciplinary collaborations have initiated translational studies in an effort to harness naturally occurring diseases in companion animals to accelerate the development of new treatment modalities, drugs, and device inventions. These synergistic collaborations can identify clinically relevant models that offer the opportunity to conduct rigorous translational investigations. However, the relationship between craniomaxillofacial diseases in companion animals and humans has been widely overlooked. We report here an innovative and visionary 2-d symposium that was organized to gather professionals working on craniomaxillofacial disorders and solutions in humans and/or animals from multiple disciplines, including veterinary physicians, basic scientists, biomedical engineers, physicians, and dentists. The symposium provided a platform for junior and senior investigators and basic science and clinical researchers to network, collaborate, and develop a new clinical and translational framework for accelerated therapy development
