Abstract

Tapak dara or Madagascar Periwinkle (Catharanthus roseus [L] G.Don), a natural plant, is empirically reported to have promising anticancer activity. To elucidate its mechanism, a research was conducted to investigate the possible ethanol extract of  C.  roseus in inducing apoptosis on breast cancer cell line (T47D). Antioxidant activity of C. roseus was investigated as well. Sub-G1 flowcytometric apoptotic analysis result showed that extract of C. roseus at 6.25 μg/mL induced apoptosis for 26.365%. Increasing extract concentration resulted an increasing apoptotic level as well, extract at concentration of 12.5 μg/mL induced apoptosis for 22.235%.  Meanwhile doxorubicin at concentration of 10  μg/mL induced apoptosis for 36.055%. The antioxidant activity was determined by using  in vitro assay: inhibition of  2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging  activity. Antioxidant activity of  C. roseus extract were compared to quercetin and butylated hydroxyanisol (BHA), as positive controls.  The results showed that DPPH IC50 of C. roseus extract, quercetin and BHA were 358.411 μg/mL, 19.200 μg/mL  and  94.178  μg/mL, respectively. We suggest that  C. roseus extract had a potential anticancer activity by inducing apoptosis.

Abstract

Various diseases including cancer and cardiovascular diseasesare induced by free radicals via lipid peroxidation, protein peroxidation, DNA damage, and cellular degeneration in thecells.Piper betle L.,commonly called betel,belongs to thePiperaceae family.It originated from South and South Eas tAsia,and has been used as a traditional medicine by people theredue to its medicinal properties.In the present study, free radicalscavenging activity of ethanolic leaves extract of Piper betle L.together with its different solvent fractions(hexane,ethylacetate,butanol,and water)were evaluated by DPPH freeradical scavenging assay.The ethanolic extract and the ethylacetate fraction had shown very significant DPPH (1,1)diphenyl)2)picryl)hydrazyl) radical scavenging activitycompared to the other fractions.In DPPH free radical scavengingassay,the IC50 value of the ethanolic extract and the ethyl acetate fraction were found to be 17.431g/mL and 11.53 1g/mL, respectively. The free radical scavenging activity was assumed due to the total phenolic content.The total phenoliccontent was found to be highest in the ethanol extract(277.68µgEGCG/mg)and the ethyl acetate fraction(559.38µgEGCG/mg).The results concluded that the ethanolic leaves extract of Piper  betle L. and its ethyl acetate fraction have a consider ably freeradical scavenging activity.

Abstract

Objective of this research is to investigate the influence of dextrin and lactose in preparation of dosage form from Centella asiatica (CA) ethanol extract. Powders dosage form of CA ethanol extract was prepared by kneading method. Previously, it had been known that to create CA extract concentrate long time is needed, i.e. more than 7 days. Drying preparation of CA extract by thin layer film in oven blower at 50oC gave a shorter drying time, i.e. 6 hours but it gave sticky form at the end of process. Preparation process to produce powders dosage by using dextrin and lactose was succesfully investigated in our laboratory. It resulted that dextrin was appropriate filler for preparation of CA extract powder. Powder dosage form of CA extract could be obtained after 6 hours of drying and using 30% w/w of dextrin (based on the weigh of wet extract at density of 1,000 gr.mL-1). Difference on amount of dextrin in CA extract gave influence on water content, acidity (pH), compressibility index, haussner ratio, flow propert,y and angle of repose significantly.

Abstract

With about 120 species, Aglaia is one of the largest genera of the plant family Meliaceae (the mahogany plants). Various Aglaia species have been investigated since the 1960s for their phytochemical constituents and biological properties. This research objective was to find secondary metabolites that have activity as anti-breast cancer compounds from endemic Indonesian Aglaia, such as Aglaia angustifolia Miq. Two cholestan type steroids, stigmast-5en-3α-acetat (1), as a new steroid with α-sterochemistry of acetyl moiety at C-3 and 23a-homostigmast-5en-3β-ol (2), with unusual side chain were isolated for the first time from the stem bark of Aglaia angustifolia Miq or known as segara tree in Kalimantan. The chemical structures of two steroids were identified with spectroscopic data, including IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, NOESY, 1H-1H COSY) and HRTOF-MS, as well as by comparing with previously reported spectral data. These two steroids were isolated for the first time from this genus. Steroids 1 and 2 were evaluated for cytotoxic activity against MCF-7 breast cancer cells and showed weak activity with IC50 values of 829.0 and 903.0 µg/mL, respectively.

Abstract

ABSTRACT. The Aglaia species, which contains triterpenoids, is the most numerous in the Meliaceae family. Aglaia foveolata (A. foveolata) is a type of plant that has many benefits, as medicinal ingredients. The potential of this plant is inseparable from the content of various bioactive compounds. This study aims to isolate, characterize the active compound from the twigs of A. foveolata and test its activity as an antibacterial. Three dammarane-type triterpenoids were isolated from the A. foveolata twigs which is, namely dammar-24-en-3β,20-diol (1), an epimeric mixture of shoreic and eichlerianic acid (2, 3). Their chemical structures were determined based on spectroscopic data using infrared, high-resolution mass spectrometry, and including one and two-dimensional NMR techniques, as well as through data comparison of the reported compound. Compound 1 was reported for the first time to be successfully isolated from this species. All these substances were tested for the first time for their antibacterial activity against two Gram-positive bacteria Staphylococcus aureus and Bacillus subtilis and two Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa, through this study. Compound 1 was inactive, the epimeric mixture of 2 and 3 showed moderate antibacterial activity with a minimum inhibitory concentration (MIC) value ranging from 31.7 to 126.6 ppm, particularly against S. aureus with a MIC value of 31.7 ppm.
