ABSTRACT:

 

Binahong (Anredera cordifolia (Ten.) Steenis) is one of the plant which is use generally for treatment of illness but no more research that explain about its chemical compound and efficacy. In this research had been done phytochemical screening, isolation and identification of chemical compound in n-heksana phase from methanol extract of that binahongs leaves. Isolation doing by thin layer chromatography (TLC), vaccum liquid chromatography (VLC) and column chromatography (CC). Isolate was purified by TLC preparation and then two dimension TLC by using two eluens that has different polarity to know whether that isolate still had one spot at TLC plate. The chemical structure of isolate was identified by UV-Vis spectrophotometre, IR spectrophotometer, GC-MS. The result of phythochemical screening contains steroid, triterpenoid and volatile oil. The result of datas analyses from UV-Vis, IR and GC-MS spectrum showed that isolate which had been identified given maxsimum absorbance at 230 nm has functional groups such as O-H, C-H, C-C, C=C and C-O with molecural weight 281. Based on data base Willey275.L assumed that chemical compound from n-heksana phase is 4-terpineol with 97% similarities.

Abstract: Problem statement: Propolis has been ethno medically claimed to possess a wide array of biological activities including anticancer activity. The purpose of this research was to verify the folklore claim. Approach: This study was performed in a human breast carcinoma cell, MCF-7. Extract of propolis from different solvent, ethylacetate and n-buthanol showed induced apoptotic cells was detected by flow cytometry. Results: The results demonstrated that ethylacetate extract of propolis can induce apoptosis in MCF-7 as large as 13.21% during the 24 h incubation. On the other hand, doxorubicin is able to induce apoptosis as large as 18.89% during the 24 h incubation. Conclusion: The extracts of propolis ethylacetate had cytotoxic activity and triggers apoptosis on MCF-7 cells.

Abstract : Clove buds and clove leaves (Syzygium aromaticum (L.) Merr. & Perry.) contain of volatile oil, but most people only use the buds for traditional medicine. Due to the statement above, author had made the research to isolated the volatile  oil  of  buds  and  leves  clove  by using  water  and  steam  distillation  then identified by using Thin Layer Chromatography (TLC) and Gas Chromatography – Mass Spectrometry (GC-MS). The result showed that there is a differences of total value from clove buds and clove leaves. Clove buds yield 12,94 per cent of volatile oil, containing 94,86 per cent of eugenol and clove leves yield 5,68 per cent of volatile oil, containing 98,30 per cent of eugenol. Meanwhile, the chromatogram based on the examination by using TLC and GC-MS from cloves buds and cloves leaf didn`t show any significant differences. Both of them have a same chemical constituent called eugenol.nevertheless, there are also the other different component on clove buds and clove leaves. The chemical constituent of clove buds that didn`t exist on clove leaves are Eugenyl Acetate, Methyl eugenol, and α-Humulene. On the opposite, the chemical constituent of clove leaves that didn`t exist on clove buds are

4,7,10-Cycloundecatriene, CaryophylleneOxyde, dan 3-Cyclohexen-1-ol,5-(2- butenylide).

Abstrak : Bunga cengkeh dan daun cengkeh (Syzygium aromaticum (L.) Merr. & Perry.) mengandung minyak atsiri, tetapi masyarakat pada umumnya menggunakan bunga cengkeh untuk obat tradisional. Berdasarkan hal tersebut diatas, penulis melakukan penelitian yang bertujuan untuk mengisolasi minyak atsiri yang berasal dari bunga dan daun cengkeh dengan metode destilasi uap dan air, kemudian minyak atsiri dari bunga dan daun cengkeh diidentifkasi secara Kromatografi Lapis Tipis dan Kromatografi Gas-Spektrometri Massa. Hasil penelitian menunjukkan perbedaan kadar total minyak atsiri yang berasal dari bunga cengkeh sebesar 12,94% dengan kandungan eugenol sebesar 94,86 %, dan kadar total minyak atsiri dari daun cengkesebesar 5,68% dengan kandungan eugenol sebesar 98,30 %. Sedangkan dari pemeriksaan Kromatografi Lapis Tipis dan Kromatografi Gas - Spektrometri Massa dari minyak atsiri daun dan bunga cengkeh diperoleh bercak kromatogram yang tidak jauh berbeda,

Abstract: According to literatures, many plants of Papilionaceae family such as red bean (Phaseolus vulgaris L.), green bean (Phaseolus aureus Roxb.) and soybean (Glycine soja Sieb. & Zucc.) contain favonoid,  isofavonoid  and vitamin E. They all have antioxidant activity and are potential to reduce free radical. This research was aimed to identify secondary metabolites of crude powders and extracts of red bean, green bean and soybean. The bioactivity of each extracts was evaluated with Brine Shrimp Lethality Test (BSLT) method for preliminary assesment of toxicity. It was also evaluated for antioxidant activity using 1,1 difenil-2-pikrilhidrazil (DPPH) method. The results showed that red bean, green bean and soybean contain saponin, favonoid, steroid/triterpenoid, coumarin, and tannin. The result of BSLT showed that LC (Lethality Concentration 50) of red bean was 213.21 ppm; green bean 390.71 ppm;

and soybean 252.75 ppm. The result of DPPH tests showed that IC (Inhibition Concentration 50) of red bean was 47.54 ppm; green bean 95.08 ppm; and soybean 90.43 ppm.

 

 

Keywords: Papilionaceae, free radical, antioxidant, DPPH, BSLT.
