Abstract

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.

Abstract

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 one's 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).

Abstract

Wati(Piper methysticum Forst.f.)leaves has been used as narcotic in some parts of Irian Jaya since longtime ago. The GCMS analysis of wati leaves organic extracts(hexane,chloroform, methanol)has detected 48 components consisted alkanes,oxygenated hydrocarbons, fatty acid, steroids and alkaloids,including 5 major components, i.e. dihydro kawain,anisol p-undecyl, 2,3-dihydro-3,5-dihydroxy-6-methyl-4H-pyran-4-on, levulinic acid and one of unknown component.Forty-three other minor components will be discussed.

Abstract

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).

Abstract

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.
