Abstract

This study was done to determine the chemical compounds and antibacterial activity of ki cengkeh (Urophyllum arboreum (Reinw.ex. Bl.) Korth.) essential oil. Ki cengkeh has already known as medicinal plant in some places in Indonesia. This might be correlated with its chemical compounds. The analysis of chemical compounds of ki cengkeh essential oil was done by GC-MS, while antibacterial test was done by paper disc method against 3 bacteria isolates (Staphylococcus aureus, S. epidermidis and Eschericia coli). The result of GC-MS analysis showed that there were 25 compounds with the concentration more than 1% and carryophylen oxide as the highest compound (12.03%). The highest antibacterial activity was found against S. epidermidis.

Abstract

Terminalia is the second largest genus of Combretaceae family, consists of 200 species distributed in the tropics and subtropics. Many species of Terminalia are well kown in traditional medicine  in several countries of Africa and Asia. In this study, bark extracts of four species of Terminalia (T. catappa, T. citrina, T. bellirica and T. macadamii) were evaluated for their in-vitro anti-inflammatory and antioxidant activity. Determination of the anti-inflammatory activity was carried out using red blood cell membrane stabilization assay and the antioxidant activity was carried out using DPPH free radical scavenging and ferric reducing power assay. Estimation of total phenolic   content was carried out using Folin-Ciocalteu reagent, while  total flavonoid content using alumminium trichloride reagent. The results showed that extract of T. catappa has the most potent anti-inflammatory activity (IC50= 97,83±0,0100 ?g/mL) and the most powerful  antioxidant activity of DPPH free radical scavenging (IC50= 21,8900 ± 0,0264 ?g/mL) and ferric reducing power (IC50= 87,1533 ± 0,04163 ?g/ mL). The weakest anti-inflammatory activity was T. citrina extract (IC50= 159,35±0,0200 ?g/mL), whereas T. bellirica extract demonstrated the weakest antioxidant activity of  DPPH free radical scavenging (IC50= 44,4867 ± 0,0153 ?g/mL) and ferric reducing  power (IC50= 140,89±0,04 ?g/mL). The extract of T. citrina has the highest content of total phenolic (84,8167 ± 0,53407 mg GAE/g) and flavonoid (23,1200 ± 1,7149 mg RE/g) while the T. macadamii extract has the lowest content of total phenolic (24,3700 ± 0,0173 mg GAE/g) and flavonoid (13,2667 ± 0,3386 mg RE/g).

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

Cempirit [Ervatamia svhaerocarva Burck.(Apocynaceae)] is a sticky plant found in Indonesia. This species had long been used as traditional medicine for skin diseases and ulceration of nose.Major biologically active compound was isolated from bark of E.sphaerocarDa by using combination of chromatography techniques (Thin Layer Chromatography,Colum Chromatography and High Performance Liquid Chromatography).The structure of this compound was elucidated by spectroscopic methods, mainly by NMR (Nuclear Magnetic Resonance) spectral. This compound was determined as indole alkaloide called Tabernaemontanine.
