METIL EUGENOL, KHEMOTIPE DARIMINYAK ATSIRI Melaleuca spp. (MYRTACEAE) YANG TUMBUH DIKEBUN RAYA CIBODAS Murningsih, Tri; Chairul, Chairul; Kuncari, Emma Sri

Publisher : Research Center for Biology-Indonesian Institute of Sciences

The essential oils of the fresh leaves of Melaleuca spp. (M. alternifolia Cheel, M. ericifolia Sm., M. squarrosa Donn, and M.genistifolia Sm.) from Cibodas Botanical Garden, Indonesia were isolated by a hydrodistillation method and analysed by a gas chromatography/mass spectrometry (GC/MS) technique. The various Melaleuca species showed differences within their relative essential oil compositions. The oils from all samples were of the methyl eugenol (10.30-71.25%) chemotype. The others major constituent were terpinen-4-ol (38.49%), linalool (19.65%) and bis(2-ethylhexyl)phtalate (66.09%) in the M. alternifolia, M. ericifolia, and M. genistifolia respectively.

ISOLASI GLUKOMANAN DARI DUA JENIS ARACEAE: TALAS {Colocasia esculenta (L.) Schott} DAN Iles-iles (Amorphophallus campanulatus Blumei) Chairul, Chairul; Chairul, Sofnie M

Talas {Colocasia esculenta (L.) Schott} and Iles-iles (Amorphophalus campanulatus Blumei) have been used as source of carbohydrate especially in tropical regions, mainly in East Indonesia. Talas and iles-iles, that contains carbohydrate and several substances for instance glucomannan would form viscous liquid and were used as emulgator, capsule cosmetics and dietary.The research was conducted to separate glucomannan from starch of talas and iles-iles fresh and dry (powder).The methods base on speed of revolution (centrifuge) in 5000 to 19000 rpm and the duration of rotation was 10 to 40 minutes and the filtrate was precipitated by using several alcohols (methanol, ethanol, propanol, isopropanol and isobutanol). The results showed that speed of rotation 17 x 1000 rpm with 10 minutes rotation resulted in good glucomannan separation from starch.Ethanol and isopropanol were the best solvent to separate glucomanan from dissolved starch in the filtrate with ratio 2 : 3 and for dry material, and the maximal agitation reached after 2 hours. Glucomannan content on fresh material was higher than as in talas (4.08 %) and iles-iles (5.64 %), compared to these in powder (dried) of talas (3.87 %) and iles-iles (5.41 %). The purerity of isolated glucomannan was higher compared to control.

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.

The development of method to explore natural chemical product initially from plants were started from the beginning and generously from time to time from the conventional ones until sophisticated equipments.The value of plants as food,cosmetic and medicines resources needs specific instruments and methods for determining the quantity as well as quality of the materials in plants.This paper describe in detail one of the sophisticated equipments commonly used for analyzing and isolating bioactive compounds the so called High Performance Liquid Chromatography (HPLC).

EFEK HYPOGLIKEMIK EKSTRAK ALKOHOL HERBA MENIRAN (Phyllanthus niruri L.) PADA KELINCI PUTIH JANTAN Chairul, Chairul; Jamal, Yuliasri; Zainul, Zuherti

A study on the influences of alcohol extract of Meniran or Phyllanthus niruri L. (Euphorbiaceae) to blood glucose concentration in rabbits (Oxytolagus cuniculus) had been carried out using glucose tolerance method.The extract was administered orally at 10, 20, 30, 40 and 50 mg/kg BW.Prior to tfie extract administration, all rabbits were put on hyperglycemic condition by injecting glucose solution intravenally at dose of 0.5 g/kg BW.The blood glucose concentration was measured every one hour starting at 2 hours before and until 7 hours after administration. Antidiabetic drug,tolbutamid 250 mg/kgBW.was used as control.The results indicated that extract with dose at 30 mg/kg BW gave a hypoglycemic effect similar to control (Tolbutamid). The blood glucose decreased regularly as the extract dose being higher.Using statistical analyses showed significant differences among the groups, especially after the 2 and 3 hours of treatment (P<0.05).

Antipyretic effect of alcohol extract ofilalang flmperata cylindrica L) root on white rat males had been studied using fever tolerance method.Experimental animals were induced to fever by injecting 0.9 ml/kg BW vaccine kotipa orally.Alcohol extract 5, 10, 30, 50,100 and 150 mg/kg BW was given one hour after injection.The body temperature was measured before injection and every half an hour until the fifth hour after injection.Paracetamol 200 mg/kg BW was used as control.Data were analyzed using ANOVA with the body temperature (T), the time interval (P) and extract doses being given (C) as parameters.The results showed that body temperature increased TC from the basal temperature at the third hour after injection of vaccine.The body temperature did not change significantly at the lower extract doses(5-30 mg/kg BW)(P>0.05),while higher doses (30-150mg/kg BW) linearly lowered the body temperature significantly (P<0.05).The extract dose at 50 mg/kg BW lowered the body temperature similar to paracetamol 200 mg/kg BW.

New drug discovery from natural products (bio-prospecting) is not an easy works and takes time, big budget, human resources etc. some important approaches must be taken in order to get success. A preliminary observation of biologycally active components is impotant approach in order that more selective in collecting research materials in the field. This approach is purposed to pacilitate (make easier) the next step research process later in the laboratory level. Several Methods of preliminary observaton of biologyvcally active components had been carried out in the field, but the general guideline of fast observation had been used e.g. 1). Etno-botany (Etnomedicine and Etnopharmacology), 2). Chemotaxonomy, 3). Organoleptic, 4). Chemical (reagent kit) and 5).Simple bioassay in the field (fish posion test, insecticide). Besides that collecting the herbarium specimen as well as research materials for any scienfitic and laboratory works. This paper described these approaches in order to make useful methods to researchers, who go to the field and they could collect more selective research materials before bring them to laboratory.
