Liquid smoke made from green betel leaf (Piper betle L) and red betel leaf (Piper crocatum Ruiz & Pav) has been made by pyrolysis. To determine the allegations of the chemical compounds contained in these two liquid smoke, they were tested by Gas Chromatography–Mass Spectrometry (GC-MS) method. Based on the test results it was found that there were 7 suspected compounds in the liquid smoke of green betel leaf and 30 compounds in red betel liquid smoke. The main compounds contained in the liquid smoke of green betel leaf are Isamoxole as the anti-allergic, 5,10-Diethoxy-2,3,7,8-tetrahydro-1H, 6H-dipyrrolo [1,2-a; 1', 2'-d ] Pyrazine as an antifungal and 3,5-Dimethoxyphenol has the potential to be antibacterial while in red betel leaves are 4- (1H-1,3-Benzodiazol-2-yl) phenol and Benzene, 1,2,3-trimethoxy-5- (2 -propenyl) - Bioactivity potential of the two compounds has not been found.

Agarwood Oil

ABSTRACT: Agarwood oil is a highly prized type of oil due to its unique aroma. The oil is extracted from the fragrant resin found in the agarwood tree (trunk).  The unique aroma and quality of agarwood resin and oil are contributed by the presence of certain chemical compounds. In this work, analysis and comparison of the chemical compounds of agarwood oil from A. malaccensis, A. sub-integra and a mixture of both were conducted.  The essential oils were diluted in hexane (5%) prior to gas chromatography mass spectrometry (GCMS) analysis performed using Agilent GCMS 7890A coupled with MSD quadrupole detector 5975 C.  Separation of analytes by gas chromatography was carried out using a Hewlett Packard HP-5MS silica capillary column (30 m X 0.25 mm X 0.25 mm). A total of 107 compounds were identified from the three samples of agarwood oils. Fifty-five (55) components were identified in A. malaccensis sample which contributes to the largest portion of the total compounds. About 20% of the compounds identified were aromatic and sesquiterpenes which have been revealed to be the main active compounds of agarwood oils which also give the aroma and pleasant odour of agarwood. Different compositions or profile of chemical components were found in agarwood oils from the two different species. Two compounds were commonly identified in all three samples namely 3-phenyl-2-butanone and alpha-cubebene.  Further studies are needed to refine the results which later can be used to assist detection and authentication of agarwood as well as its scientific-based grading. ABSTRAK: Minyak gaharu merupakan sejenis minyak beraroma unik yang mendapat permintaan tinggi dan mahal. Minyak ini diekstrak daripada resin beraroma yang terbentuk di dalam batang pokok gaharu. Keunikan aroma dan kualiti resin dan minyak gaharu ini bergantung kepada kehadiran bahan kimia tertentu. Penyelidikan ini menjurus kepada analisis dan perbandingan bahan-bahan kimia yang terdapat dalam minyak gaharu daripada spesis A. malaccensis, A. sub-integra dan campuran kedua-duanya. Minyak gaharu dilarutkan di dalam 5% heksana sebelum dianalisis menggunakan kromatografi gas Agilent GCMS 7890A berserta spektormetri jisim (MSD quadrupole detector 5975 C). Kolum kapilari silika Hewlet Packard HP-5MS (30 m X 0.25 mm X 0.25 mm) digunakan untuk pemisahan bahan-bahan kimia tersebut. Sejumlah 107 kompaun dikenalpasti dalam ketiga-tiga sampel minyak gaharu tersebut dengan 55 kompaun didapati di dalam sample A. malaccensis. Ini merupakan bahagian terbesar daripada keseluruhan kompaun. Sebanyak 20 % daripada keseluruhan kompaun yang dikenalpasti adalah daripada kumpulan seskuiterpena dan bersifat aromatik, juga merupakan kumpulan yang bertanggungjawab memberi aroma yang unik kepada minyak gaharu. Setiap spesis didapati mempunyai komposisi atau profil bahan kimia yang tersendiri. Dua kompaun iaitu 3-phenyl-2-butanone dan alpha-cubebene ditemui dalam ketiga-tiga sample yang dianalisis. Kajian lanjut adalah perlu untuk memurnikan dapatan hasil penyelidikan yang berpotensi bagi membantu pengenalpastian gaharu berserta pembangunan penggredan gaharu yang lebih saintifik.

Objective: This study is designed to hunt for the presence of bioactive compounds from three marine sponges collected from Kovalam.Methods: Zoochemical analysis is performed to screen for the presence of secondary metabolites. Based on those results, only two sponges which showed a significant presence of secondary metabolites has been subjected to gas chromatography-mass spectrometry (GC-MS) analysis to identify the unknown chemical compounds present in those sponges.Results: On analyzing the results, two sponges, namely, Dysidea herbacea and Sigmadocia pumila, has shown a significant presence of secondary metabolites while the third sponge Acanthella elongata have shown moderate presence of secondary metabolites. Since the first two sponges results are remarkable, these two samples have been subjected to GC-MS analysis to separate and identify the unknown chemical compounds present in the sample.Conclusion: Samples, namely, D. herbacea and S. pumila, indicated the presence of several components. From both the sponges, eleven different secondary metabolites were identified by GC-MS. Most of these compounds are widely used in cosmetic, pharmaceutical, and other industries and therefore a vital source for industrial biotechnology and related products in healthcare and skincare.Keywords: Dysidea herbacea, Sigmadocia pumila, Acanthella elongata, Secondary metabolites, Gas chromatography-mass spectrometry analysis, Bioactive compounds.
