Some attempts have been carried out to synthesize polycyclic heterocyclic compounds derived from new benzocarbazoles (1). New 6-(3-indolyl)benzo[b]-carbazoles (2a) have been synthesised in good yields from the reaction of simple indoles and o-phthaldialdehid in methanol catalysed by p-toulenesulfonic acid monohydrate. Their precise structure were established by microanalysis, spectroscopy, and X-ray crystallography of the benzo[b]carbazole (2a).Keywords: indoles, polycyclic heterocyclic compounds, benzo[b]carbazoles

The aim of the study was to find out a formula of granules giving a constant release of drug and also to search for the influence of pH on the drug release from the formula. One type of drug-resin complexes was used in this study ion exchanger the complex of diclofenac sodium and dowex. After 12 hours mixing the drug-resin complex was dried at 40 oC in an oven for 3 days. Afterwards, they were granulated and shieved. The particle size used were 20-40 mesh. The granules were tested for the dissolution of diclofenac sodium from the granules. The dissolution experiments were performed in a modified model of USP XX and the dissolution media used were phosphate buffer with the pHs of 5,8; 6,8 and 7.6 and the temperature was maintained at 37 oC. The amount of diug released in to the medium was assayed spectrophotometrically. The extent of dissolution was expressed as dissolution efficiency in 8 hours (DE8, % ). The results showed that the extent of dissolution of dtclofenac sodium from the granules complexed with the resin were low. The correlation between the amount of drug release from the complex and time was linier with the highest coefficient correlation having the ratio of l:5. The higher the pH values of the media, the higher the drug release from granules was. The drug release from drug-resin complex was well controlled which may be used for making a sustained release dosage form.Key Word : sustained release, diclofenac sodium, ion exchanger resin, granules

Furosemide is a poorly soluble diuretic drug, the solubility of which can be enhanced by solid dispersion with polyvinylpirolidon (PVP). The solid dispersion system was prepared by a solvent method in various ratios of 1 : 5 and 1 : 7 of the drug and PVP, respectively, in order to improve furosemide bioavailability. The bioavailability of furosemide - PVP solid dispersion was compared with pure furosemide (control) and Lasix (reference). The study was done in a cross over design with a single-dose peroral that administered to the white male rabbits (n = 6). Furosemide blood levels were determined spectrofluorometrically by an extraction method. The area under the blood concentration-time curve AUC0 - , peak blood concentration Cmax and time to reach peak blood concentration Tmax were used to compare their bioavailabilities. The solid dispersion systems produced a higher extent of bioavailability than pure furosemide (P < 0,05). On the contrary, no statistically significant difference about the extent of bioavailability between solid dispersion and Lasix (P > 0,05). Finally, furosemide – PVP solid dispersion (1 : 7) was the best formulation with the highest extent of bioavailability and bioequivalence with the Lasix formula.Key Word : Solid dispersion, solubility, dissolution, bioavailability, furosemide.

PROTOPLAST SUSPENSION CULTURE OF LEAVES MESOPHYLOF Centella asiatica (L.) Urban AND QUALITATIVE ANALYSIS ASIATICOSIDE Prihastanti, Erma; Soegihardjo, C. J.; Purbaningsih, Susiani

Centella asiatica leaves has been used as diuretic, antihypertensi, anti leprae, skin infection, burning skin and celloid. Cells suspenson culture of mesophyll of Centella asiatica leaves were carried out in three steps: isolation, purification, and cell culture. The aim of this research is to investigate the influences of leaves position (age of leaves) and concentration of macerozyme R-10 for cells number and viability, and the influence of sucrose concentration for cells growth and biosynthesis of asiaticoside. Isolation and purification of mesophyll cell has been performed using factorial completely randomized design. The first factor was leaf position (age of leaves), and the second factor was concentration of macerozyme. Collected data were analysed using Anova and Duncan’s test at 0.0 – 2.5 – 5.0 and 7.5 per cent respectively. Asiaticoside produced by cell biomass were analyzed qualitatively using thin layer chro- matography. The result revealed that mesophyll cells could be used as explant for suspension culture. The highest biomass produced with highest viability were found in cells isolated from second leaves treated with 0.1% macerozyme (1.32 . 107 cells/ml). Addition of sucrose to suspension culture medium produced higher packed cells volume (pcv) percentage than no sucrose was added, (0% sucrose gave pcv 8.5%, 2.5% sucrose pcv 22%, sucrose 5% pcv 21.5%, and 7.5% sucrose pcv 15.75%). The asiaticoside production not only depended on sucrose, because without any sucrose was added, the asiaticoside was also available..Key Words: Cell suspension culture, mesophyll, Centella asiatica (L.)

A research has been conducted to study the sedative effect of the Clary sage oil (Salvia sclaria, L), using an olfactory aromatherapy method, on male white mice, which have been tested using rotarod, platform and chimney tests. Clary sage oil was given to the male white mice in three different exposed times : 0.5, 1, and 1.5 hours. As a reference standard was used diazepam 170 ug/kg body weight (intraperitoneal). The research indicates that the administration of Clary sage oil can indeed cause the sedative effect. There is also a correlation between the exposure time of Clary sage oil and the sedative effect observed. Key-words : sedative effect, clary sage oil, olfactory aromatherapy

Tensigard is a phytofarmaca product of Agromed ( PT. Phapros Tbk., Semarang) formulated for antihypertension therapy. The product comprises celery extract (Apium graveolens) 75 % and kumis kucing extract (Orthosiphon stamineus Benth) 25 %. The aims of the research is to study whether Tensigard has an effect to decrease blood pressure in the normo and hypertensive (adrenaline induced hypertension) experimental animals. The specific aim of the study is to determine the D50 value of Tensigard to lower the blood pressure of the hypertensive experimental animals. The tests were conducted using anesthetized using anesthetized cats which were randomly divided into two groups, each of which consisted of 35 normotensive cats and the other 35 cats with hypertension (due to adrenaline treatment, in which the blood pressure was increased about 1,5 times than normal value). Furthemore, each group was devided into seven sub groups, each of which consists of 5 cats. One sub group was used as the control group, while the remaining sub groups were treated with Tensigard (6 dosage levels). The results of the studies indicated, that Tensigard has a hypotensive effect in the cats,either with normal or hypertension (adrenaline induced). The D50 value of the hypotensive effect in hypertensive cats is 16,37 ï± 1,08 mg/kg BW., in which the extrapolation of this dosage value for a 50 kg, human being is about 249,05 mg.Key Word : tensigard, antihypertension, effective dosage
