Karoune S, Kechebar M S A, Djellouli A, Belhamra M, Rahmoune C, Ksouri R
Abstract
The mainly aims of this work is to study the interspecific variability of polyphenol contents and anti-radical activity of two species, Acacia albida and Acacia raddiana in order to select the best species in both respects, quantitative (phenolic content) and qualitative (antioxidant activity). Initially we performed a sequential extraction with four solvents: Hexane, Chloroform, Ethanol and Water on three organs leaves, fruit and bark, collected on field in the Tindouf region. The eighteen extracts obtained were assayed for total polyphenols by the Folin-Ciocalteu method and an evaluation of the antioxidant activity by testing the free radical DPPH. Results showed significant differences between organs of both species for the three extracting solvents as well as for the polyphenol contents and antioxidant properties. The ethanol extracts of Acacia albida exhibit the best results of total polyphenol concentration with 100.94 and 59.50 mg GAE.g-1DW, respectively for the leaves and bark. The IC50 values of the DPPH test is in favor of leaves and bark of Acacia albida for both aqueous and ethanolic extracts. For the ethanolic extract we recorded IC50 values of 28 and 26 µg.ml-1 for leaves and bark, while the aqueous extract exhibited the values of 22.5 and 29 µg.ml-1 for leaves and bark, respectively. Both extracts were analyzed by high performance liquid chromatography (HPLC-DAD). These results allow us to conclude that the Acacia albida is the most active species in comparison to Acacia raddiana and the ethanol and aqueous extracts of leaves and bark have achieved the best values.

Abstract
Barringtonia acutangula belongs to family Barringtoniaceae, useful in the treatment of wound, syphilis, liver troubles. The present study has been attempted to evaluate pharmacognostical and physico-chemical studies of Barringtonia acutangula fruit and seed. Transverse section of fruit shows the presence of mesocarp, endocarp and endosperm. Seed shows the presence of endocarp, sclereids, endosperm and starch grains. The powder microscopy of fruit and seed show lignified sclereids, fragment of endosperm, starch grains, fibres, crystals and xylem vessels. Histochemical tests of fruit reveal the presence of lignins, starch and phenols which are characterised by different histological zones. Physico-chemical studies such as ash value, extractive value, moisture content, powder behaviour and fluorescence analysis were carried out on both fruit and seed. Total ash, water soluble and methanol soluble extractive values were found more in fruit than seed. Moisture content was found more in seed. Phytochemical screening of methanolic extract indicates the presence of important secondary metabolite like carbohydrate, glycoside, saponins, alkaloids, tannins and phenols. These studies help in identification and authentication of the plant material. Such information can act as reference information for correct identification of particular plant and useful in making a monograph of the plant

Chaveerach A, Lertsatitthanakorn P, Tanee T, Puangjit N, Patarapadungkit N, Sudmoon R
Abstract
Tiliacora triandra has long been used as a traditional medicine and in cuisine in Thailand and neighboring countries. Leaf samples were randomly collected and extracted with methanol. The extracts were chemically analyzed by gas chromatography-mass spectrometry (GC-MS), and free radical scavenging activities were assessed by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. After drying and re-dissolving the extracts in dimethyl sulfoxide (DMSO), cytotoxicity and genotoxicity tests were performed using lymphocytes and HeLa cells. The major components found in all extracts, with yields of 8.59-26.29%, were vitamin E, phytol and 1-cyclohexenylacetic acid. At a concentration of 8.4 mg/ml, the methanol extract reduced the concentration of free radical DPPH (DPPH•) to 50% (EC50). Lymphocyte viability was 72.78% when treated with 10 mg/ml extract, a concentration that significantly affected DNA (p<0.05). The viability of HeLa cells was 50% (IC50) when treated with 0.41 mg/ml; this concentration also significantly affected DNA (p<0.05). The extracts showed good antioxidant activity, in agreement with their high content of vitamin E, and significantly affected the stability of lymphocyte and HeLa DNA, though without major toxicity at the cellular level. These results reveal guidelines with regard to consumption of this plant, which is particularly common in Thailand.

Abd. Rahim, Andi Arjuna, Ermina Pakki, Syatriani A. Syaiful, Abd. Muzakkir Rewa, Gemini Alam, Mufidah Murdifin
Abstract
Black glutinous rice (BGR) is one of widely used materials for Buginese and Makassarnese people as traditional medicine ingredients and food compositions. It is a daily-consumed mixture for people with health problems such as diabetes mellitus, asthma, post-partum treatment, and gastritis. It has antioxidant effects due to its unique natural colorants, anthocyanin which been claimed as the main cause of its early-mentioned medicinal effectiveness. In order to have clear scientific evidence, this research was aimed to determine HPTLC profile and antioxidant activity of BGR. Black glutinous rice was extracted with acidic methanol, ethanol, and acetone solvents, then the analysis of anthocyanin was determined by the pH-differential and high-performance thin-layer chromatography (HPTLC) method. The antioxidant activity was investigated using 2,2-diphenyl-1-picryl hydrazine (DPPH), Nitric Oxide (NO) radicals scavenging, and β-Carotene bleaching (BCB) assay. The highest total anthocyanin content was found in methanolic extract (0.166% b/b), followed by ethanolic extract (0.126% b/b) and acetonic extract (0.076% b/b). The antioxidant activity was inversely significant correlated (p<0.01) with the anthocyanin content; the highest antioxidant was observed in acetone extract with IC50 of 14.49 µg/ml for DPPH, 48.97 µg/ml for NO and 131.97 µg/ml for BCB assay. Furthermore, the HPTLC profile revealed that the primary compound in all BGR samples is cyanidin-3-o-glycoside, but there is another compound content that contributes to the higher activities of the BGR acetone extract. The antioxidant activity of black glutinous rice (Oryza Sativa Linn. var glutinous) may be due to the presence of the anthocyanin and other nonpolar compounds.

23. Studies on the Enhancement of Cancer-Selective Cytotoxicity of Herbal Medicine by Combination
Susanti S, Iwasaki H, Oku H
Abstract
In this study, we evaluated the selective cytotoxicity of 9 herbal plant extracts in single or mixed doses by using a panel of normal and cancer cell lines. Single and higher doses of herbal extracts selectively suppressed the viability of cancer cells with slight toxicity to normal cells. A combination of lower doses of these extracts significantly increased the cytotoxicity to cancer cells with no adverse effect on normal cells suggesting that selectivity against cancer cells was enhanced and toxicity to normal cells was reduced by interactions between the wide arrays of compounds in the mixed formulations. We further tested for the positive or negative interactions between these crude extracts and arctigenin, the compound responsible for cancer-selective cytotoxicity in extracts of the herb Arctium lappa L. On the basis of changes in ED50 values, it was found that a combination of arctigenin with extracts from Prunus mume or Carum carvi enhanced the cytotoxicity to cancer cells with no detrimental effect on normal cells. These observations suggest that combination of herbal medicine can optimize cytotoxicity specifically to cancer cells while normal cells experience minimal toxicity. This study thus describes the optimization of herbal formulations through interactions between herbal plant extracts, and discusses the importance of this approach for enhancing cancer-specific cytotoxicity and opening a new avenue for cancer chemotherapy.

Raja S, Ramya I, Ravindranadh K
Abstract
Heart disease remains the principal cause of death claiming millions of lives every year. Owing to technology and changes in life style the myth of myocardial infarction primarily affecting elderly people has been busted with heart disease claiming significant number of lives among young people also. Myocardial infarction occurs when a section of the heart is deprived of oxygen leading to necrosis of the tissue. Isoproterenol induced myocardial necrosis came to light during the late fiftees. Conventional drugs are likely to reduce mortality, but their general applicability is limited by problems with toxicity and cost. Herbal medicine is used by more than one-fifth of the global population and it is an adept alternate to synthetic drugs. The objective of current review is to assess the cardio protective potential of phyto constituents like alkaloids, organo sulphur, carotenoids, flavonoids, glycosides, terpenoids, saponins and phenolic acid against isoproterenol induced myocardial necrosis in rats. Pretreatment of rats with these phytoconstituents significantly prevented the deviated biochemical variations such as marker enzymes, lipid profile and antioxidant parameters to near normal status. This review article provides a comprehensive account of structure, dose and medical efficacy of cardio protective phytoconstituents.

Abstract
Background and Purpose: Cardiac ischemic preconditioning represents the most powerful endogenous protective mechanism against ischemia. Spondias pinnata is rich source of flavonoids and phenolic compounds. The purpose of present study is to investigate the effect of ethanolic extract of stem bark of Spondias pinnata (100 mg/kg or 200 mg/kg) on ischemia- reperfusion injury and ischemic preconditioning of heart. Experimental Approach: Hearts from albino rats of Wistar strain were isolated and immediately mounted on Langendorff’s apparatus for retrograde perfusion. Myocardial ischemia reperfusion injury was produced by mounting isolated rat hearts on Langendorff’s apparatus and global ischemia was produced for 30 min followed by reperfusion for 120 min. In ischemic preconditioning group, the hearts were subjected to four episodes of 5 min ischemia and 5 min of reperfusion after 10 minutes of stabilization and then 30 min global ischemia, followed by 120 min of reperfusion. Myocardial infarct size was estimated macroscopically using TTC staining. The magnitude of cardiac injury was measured by Lactate Dehydrogenase (LDH) and Creatine Kinase (CK) concentration in the coronary effluent. The increase in infarct size and the release of LDH and CK are documented to be an index of I/R induced myocardial injury. Key Results: Spondias pinnata ethanolic extract significantly reduced ischemia reperfusion- induced myocardial injury in vitro, but it does not enhanced the cardioprotective effect of ischemic preconditioning. Conclusion and Implications: Administration of Spondias pinnata ethanolic extract may prevent ischemic and reperfusion induced myocardial injury probably by its antioxidant activity.
