Studi Fitokimia Ocimum Spp.: Komponen Kimia Minyak Atsiri Kemangi Dan Ruku-ruku [Phytochemical Study of Ocimum Spp.: Chemical Components of Essential Oils of Kemangi and Ruku-ruku]

Isolation of essential oils of two species of Ocimum (kemangi and ruku-ruku) were done by hydrodistilation. The chemical composition of those essential oils were analysed by GC-MS. Totaly 38 chemical components of kemangi essential oil were identified, and six of them are the major chemical constituents, ie. ethyl hexadecanoic acid (17.72 %), ethyl octadecanoic acid (14.83 %), ethyl 9-octadecenoic acid (10.62 %), methyl eugenol (4.88 %), Z-citral (7.02 %) and geranial (7.86 %), On the other hand, the essential oil of ruku-ruku contain 31 components with the main five major chemical components, i.e. ethyl hexadecanoic acid (19.33 %), ethyl octadecanoic acid (15.39 %), ethyl 9-octadecenoic acid (11.30 %), methyl eugenol (8.69%) and zerumbona (4.76 %)

Konstituen Kimia Minyak Atsiri Tiga Jenis Tumbuhan Famili Rutaceae [Chemical Constituents of Essential Oils From Three Species of Rutaceous Family Plant]

Hydrodistilation process of Feroniella lucida, Clausena harmandiana and Swinglea glutinosa leaves, 0.15%, 0.25 % and 0.20% essential oils were obtained respectively. The GC-MS analysis results shows the essential oil of Feroniella lucida contains w-desil ethanoate (38.23%), 1-decanol (11.01%), 1-decanol acetate (10.82%), and the essential oil of Clausena harmandiana contains a-pinene (12.23%) and copaene (12.40%).On the other hand, the essential oil of Swinglea glutinosa contains isocariophylene (10.09%), 3,3,7,7-tetramethyl-5-(2-methyl-l-prophenyl)-tricyclo 4.1.0.02.4 heptane (21.80%) and nerolidol type 2 (21.34%).

Perbandingan Komponen Kimia Penyusun Minyak Atsiri Sirih Liar {Piper Ornatum) Yang Berasal Dari Sulawesi Selatan Dan Pulau Seram Dengan Sirih Bias a (Piper Betle)

Comparison study on the chemical components of P. ornatum (Piperaceae) volatile oil, collected from Enrekang (South Celebes)and Sepa Village (Ceram Island, Moluccas) had been carried out by water distillation and Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Those plants had exotic performance. The sample from South Celebes had original red color leaves and strong aromatic smell, but one from Ceram Island has green color leaves and weak aromatic smell. The results showed that volatile oil content of P. ornatum from Enrekang has higher than Sepa Village (0.94% and 0.81%), while the volatile oil of common piper (P.betle) was around 0.9-1.2%. GC-MS analysis determined that volatile oil of P. ornatum had 22 chemical components. Both volatile oil indicated similar peak fragmentation, in different intensities. The major component of P. betle and P. ornatum was caryophyllene i.e. 30.01% in the red leaf, 29.41% in the green leaf and 31.05% in P. betle. Some of minor components of P.ornatum were different, from P. betle

Pengaruh Perlakuan Awal Umbi Dan Aplikasi Media Tanam Terhadap Pertumbuhan Dan Hasil Lempuyang Gajah {Zingiber Zerumbet (L.) J.e. Smith}'[effect of Pretreatment and Growth Media on the Growth and Yield of Lempuyang Gajah {Zingiber Zerumbet (L.) J.e. Smith}]

Zingiber zerumbet (L.) J.E. Smith, usually called as lempuyang gajah is belonging into Zingiberaceae. This plant has been used as traditional medicine for curing coach, asma, headache, diarrhoe and disentry. Objective of study was to determine the effect of pretreatment and growth media on the productivity of Z. Zerumbet. Research was conducted in Treub Experimental Garden,Research Centre for Biology-The Indonesian Institute of Science (LIPI), Bogor. The experiment using a Factorial Completely Randomized Design with two main factors in five replications. The first factor was pretreatment of rhizome (no treatment and pretreatment on growth chamber); the second factor was growth media i.e. soil, soil+sand+cow manure (1:1:2) and soil+sand+cow manure+compost (1:1:2:2.). The result showed that pretreatment of rhizome had significant effect on number of shoots, no pretreatment of rhizome sicnificantly had higher value. Growth media had significant effects on growth and yield which had the highest value on all parameters observed. There was an interaction effect of rhizome pretreatmnent and growth media. The best result was on the combination treatment of no pretreatment rhizome and mixed media of soil+sand+cow manure+compost(1:1:2:2.) which had the highest dry weight of rhizome
