Abstract

Betalains and anthocyanins are classes of natural and water soluble pigments. Now days, these pigments have been developed as a replacement colouring agents. One of betalain resource is dragon fruit and anthocyanin resource is tamarillo. These pigments are relative unstable in some condition, one of them is pH. This research aim is to determine stability of betalain and anthocyanin pigments by pH parameter. These pigments can be isolated by macerated methods, technically processed by chopping the fruit and than soaking in ethanol for ± 24 h. These extracts were condensed by rotary evaporator. These extracts were analysed by ultraviolet-visible spectrophotometer at wavelength (?) 200-800 nm. The absorption spectrum showed two major absorption peaks at 269 nm and 536 nm for betalain and 531 nm for anthocyanins. The result showed the optimal pH for betalain stability was at pH 5 and pH 3 for anthocyanin

Abstract

The anthocyanins in Ficus padana were extracted and identified by using high-performance liquid chromatography/diode array detection and electrospray ionization/mass spectrometry (HPLC-DAD-ESI-MS). The individual anthocyanins were identified by comparing between their mass spectral data and published data. The first compound (peak 1) was identify as a pelargonidin 3-(6”-p-coumarylglucoside)-5-(4”’-Malonylglucoside) and the second compound was identify as a pelargonidin 3-(6’’-Malonylglucoside). The second one is a major compound that taking up to 91% of the total anthocyanin content in F. padana extract. The antioxidant activity was determined with 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays and results showed that extract possessed high antioxidant capacity.

Abstract

Preparative High Performance liquid chromatography (HPLC) today is one of the popular methods to isolate anthocyanin from extract containing anthocyanins. The working principle of preparative-HPLC can be applied to the laboratory standard tupe of HPLC, so it can be used also to isolate the main anthocyanin compounds from anthocyanin mixtures. The function of fraction collector on preparative HPLC equipment were replaced by opening the mobile phase line after the exit of the detector and hold out the solution manually on the standard type of HPLC. Resolution value between the peaks and the computation time when cuts in the chromatogram peak collection mobile phase containing the analyte is of concern in these activities. The appearace of a single peak in the chromatogram of the isolates showed that the technique can be applied for the simple and fast technique of anthocyanins isolation.Keywords : isolation, anthocyanin, Ficus padana Burm.f, Preparative-HPLC, standar type of HPLC.

Abstract

Hornstedtia scyphifera var. fusiformis Holttum is endemic plant of Zingiberaceae family that distributed in Sumatera. Hornstedtia scyphifera var. fusiformis Holttum contained some secondary metabolite such as phenolic, saponin, triterpenoid and alkaloid. The biological activity of methanol, ethyl acetate, and n-hexane extracts from Hornstedtia scyphifera var. fusiformis Holttum suspended roots was tested for antibacterial and antioxydant activity. Antioxidant activity was analized by DPPH method. The antibacterial activity  was tested by used disk difussion method againts Staphylococcus aureus bacteria (gram-positive bacteria) and Escherichia coli (gram-negative bacteria). Almost all of Hornstedtia scyphifera var. fusiformis Holttum suspended roots extract were given antibacterial activity, nonetheless the biggest inhibition zone of Escherichia coli that was inhibited by n-hexane and ethyl acetate extracts which have inhibition zone 10 mm at  concentration 500 mg/L and also againts Staphylococcus aureus, the biggest inhibition by ethyl acetate and n-hexane extracts which have inhibition zone 10.30 mm at concentration 500 mg/L. Among all extracts tested, methanol extract of the possessed moderate free radical scavenging activity with IC50 = 51.89 mg/L.
