Abstract

Kapol and kapolaga are the local name in indonesia for cardamom.Although their botanical name has already clear for each species,nevertheless there were stil some confusions in regional name.Some people call it kapol for kapolaga on in turn kapolaga was called  kapol. An attempt tom distinguish which is which a GLC analysis on their essential oils were determined.From the result it distinctly can be recognised due to their GLC finger print didi not match each other so their composition were not the same. Kapol oil was totally different from kapolaga oil since its main component was 1,8-cineol,while kapolaga oil contained 1,8-cineol,terpinil acetate and geralsacetate at its main component.According to perseglove (1981)the first was belong to ammomum cardamomum and the latter was belong to Elletaria cardamomum.Since the letter type was more popular and reqodnised in international market,the first type was called as false cardamon. This is no fair since every type of cardamun had their own application and market.The result of this study willbe used as data to support the international standartd organitation (ISO) proposal.

Abstract

Dewa leaf (Gynura pseudhochina (Lour) DC) often used as herbal tea to its benefit in reducing blood glucose content. One of the active compound in dewa is pyrrolizidine alkaloid. which is active against tumor. The aim of this research was to identify the active compound of pyrrolizidine in leaves of dewa green tea, black tea and dry powder which are resulted from the experiment. The analysis of pyrolizidine was done by quantitative and qualitative methods. The separation method used for the pyrrolizidine compounds was thin layer chromatograpy using methanol:water(85 : 15) as developing solvent. The determination of pyrrolizidine content was done by TLC scanner. The result showed that the RF value of dewa green tea is 0.34 relatively equal to the pyrrolizidine standard (0.360. While the Rf value of pirolyzidine compound in leaves of dewa black tea and dry powder was 0.42 and 0.41 significantly different from pyrrolizidine standard. The pyrrolizidine compound in leaves of dewa black tea and dry powder could not be detected quantitavely by TLC scanner because its concentration was too small, where as in leaf of dewa green tea the pyrrolizidine compound was detected 0.005%. So, it could be concluded that the contents of pyrrolizidine compound in leaf of dewa green tea was higher than pyrrolizidine content in black tea and dry powder of dewa leaf.
