Abstract

An in-vivo anti-inflammatory study of pyrazoline compound synthesized from chalcone has been carried out using Paw Edema method.Compound (R)-3-(4-florofenil)-1-fenil-5-(tiofen-2-il)-4, 5-dihidro-1H-pyrazole was synthesized by milling method in alkaline condition,with no solvent addition and was conducted under room temperature. Characterization of the synthesized compound was determined using1H-NMR and HR-MS spectrometer. As for anti-inflammatory study, suspension of compound (R)-3-(4-florofenil)-1-fenil-5-(tiofen-2-il)-4,5-dihidro-1H-pyrazol was administrated orally to white female mice (Rattus novergicus) with doses 20, 40, 80 mg/kg bw, respectively. Theresult showed that the compound with doses 40 and 80 mg/kg bw exhibited insignificant difference compared with standard drugs Celecoxiband Piroksikam (p>0,05). Futhermore, all doses of compound did not cause any damage of stomach organ of mice, which is given the same“ulcer index” (Iu) with negative control (Iu 2,00). Meanwhile, ulcer index for Celecoxib of Iu 35,99 and Piroksikam of Iu 70,01.

Abstract

Plectranthus amboinicus or bangun-bangun is a traditional medicinal plant used for postpartum recovery in North Sumatera. The aims ofthis study were to detemine antioxidant and antimicrobial activity of leaves Plectranthus amboinicus. The leaves of Plectranthus amboinicuswere extracted with using n-hexane, ethyl acetate and methanol, successively. The extracts were tested to antioxidant activity assay usingDPPH with two fold dillution tehnique and ascorbic acid was used as standard. The antimicrobial activity was conducted using agar diffusionmethod against Escherichia coli, Staphylococcus aureus and Candida albicans. The Amoxsan used as positive control for antibacterialassay, while ketokenazole was for antifungi test. Extracted solvents were used as negative control. The n-hexane and ethyl acetate extractsdid not show any antioxidant activity. While, the IC 50 free radical DPPH of methanol extract was 90.96 mg/mL and ascorbic acid was 58.792mg/mL. The antimicrobial activity of n-hexane and Amoxsan againts Escherichia coli were 11.95 and 7.53 mm. The inhibition zone againtsStaphylococcus aureus were 11.30 and 11.57 mm. The antimicrobial activity of ethyl acetate and Amoxsan againts Escherichia coli were12.29 and 7.71 mm. The inhibition zone against Staphylococcus aureus were 13.72 and 11.57 mm. The n-hexane and ethyl acetate did notshow any antifungi activity towards Candida albicans. The methanol extract did not show any inhibition zone againts the selectedpathogens.

Abstract

An alkaloid has  been isolated from the stem bark of Polyalthia  rumphii and the toxicity activity was determined using the Brine Shrimp Lethality Test method againts larvae of Artemia salina  Leach. The sample was extracted by maceration method using  n-hexane and methanol  respectively. The dried sample produced  4.19  g  of  n-hexane  extract  and 80.56 g of methanol extract. The methanol extract was  extracted using acid-base method produced  0.04 g  of crude  alkaloids  which  then  was subjected  to  column chromatography  produced  three fractions.  Since the amount of fraction 1 & 3  was insufficient for further purification, only fraction  2 was purified using Sephadex LH-20 to give a  compound  coded as  DK1. The structure of DK1 was determined using 1H-NMR spectroscopy   and indicated that DK1 had aromatic rings and a methoxy group.The toxicity assay showed that  the  extract of methanol and the fraction 2 were toxic with LC50 154.98 and 243.91 ppm, respectively .

Abstract

Flavanones have been reported to possess many of interesting biological  activities  such as antimicrobe, antitumor, antioxidance, antiinflammatory, antimalaria, anticancer, and anti-HIV. In this research, a  halogenated flavanone 2-(3 -bromophenyl)chroman-4-one was synthesized by cyclization of  (E)-3-(3-bromophenyl)-1-(2-hydroxyphenyl)-2-propen-1-one  using  sodium  acetate as catalyst  under microwave  irradiation. The compound showed a good yield, and then was characterized by UV, IR and 1 H-NMR spectroscopy. The toxicity activity of this  compound was determined using Brine Shrimp Lethality Test (BSLT) method against larvae Artemia salina  Leach and showed a good activity with LC50  = 0,457 µg/mL. The result indicated that this compound  was potential  as anticancer.

Abstract

The crude polar extract of mangosteen fruit pericarp not only has a moderate antioxidant activity of (55±4 μg/mL) but also has high cytotoxicity (16±0.5 μg/mL). The high cytotoxicity presumably is caused by the presence of complex cytotoxic compounds from the mangosteen pericarp. To obtain a non-toxic extract preparation with high antioxidant activity, polar crude 50% ethanol extracts of mangosteen pericarp were partially purified using reverse-phase column chromatography with Silica C18 as the stationary phase and acetonitrile-water gradient elution. Six of the ten fractions collected had high antioxidant activities, with IC50 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging antioxidant levels <50 μg/mL. Three fractions (fractions 3, 5, and 7) with the highest antioxidant activities of (16.4 ± 0.6 µg/mL), (17.8 ± 2 µg/mL) and (17.4 ± 1.8 µg/mL) respectively, were chosen for further cytotoxicity, phenolic content and High-Performance Liquid Chromatography (HPLC) analysis. The cytotoxic tests were conducted with the Brine Shrimp Lethality Assay. Fraction 3 had low cytotoxicity (LC50 485 ± 96 µg/mL) and fraction 5 was non-toxic (LC50 ≥ 1000 µg/mL), while fraction 7 still had high cytotoxicity (LC50 2.8 ± 0.8 µg/mL). The chromatogram profiles of HPLC showed that fractions 3 and 5 contained more polar compounds than the compounds present in fraction 7. It can be concluded that the reverse phase method succeeded in the isolation of a non-toxic polar fraction, that is, fraction 5, with a significantly higher (p<0.05) antioxidant activity than in the original crude polar extracts. This fraction had a high total phenolic content of 43.3 ± 0.3 g GAE per 100 g extract.

Abstract

Plectranthus amboinicus (Lour.) is a perennial plant belonging to the family of Lamiaceae which have been widely used in traditional herbal medicine. In the present study, the extracts of the leaves of P. amboinicus that was extracted by different solvents were evaluated for their antioxidant and antibacterial properties. The fresh leaves of the plant were extracted using subsequent methanol, n-hexane and dichloromethane. The antioxidant activity was determined by DPPH free radical scavenging assay and the antimicrobial activity was tested against Escherichia coli and Staphylococcus aureus by agar well diffusion assay. The results of antioxidant activity test showed that dichloromethane extract of the leaves had the highest antioxidant activity among all with  IC50 value of 50.2 μg/mL Methanol and n-hexane extracts were still active in DPPH with IC50 value of 71.3 μg/mL and 205.9 μg/mL, respectively. Furthermore, the dichloromethane and methanol ektracts have shown a promising antibacterial activity in E. coli. The findings indicated that dichloromethane and methanol extracts of the leaves of P. amboinicus were potential further study as herbal medicine as they showed high antioxidant and antibacterial activities.

Abstract

Nanas Bongsai (Ananas comosus var. microstachys L.) is an amazing herb which is used in traditional medicine by local people of Muara Lembu district as a potion to reduce pain while menstruation period for a women. The present work was designed to investigate its probable side effects on the histopathologic changes in limph and uterus tissues after treated with A. comosus var. microstachys L extract in female white rats. This is an experimental research consisted of five treatments and three repetitions. Treatment composed of two controls (P0 and P+) and given Nanas Bongsai extract with three different dosages. Histology result of lymph show that all treatments given with Nanas Bongsai with three different dosages have different diameter average of white pulp and there is no significant changes with normal control. While observation towards histology structure of endometrium thickness with dosage P1, dosage P2, dosage P3 is 206.333±33.486; 215.667±33.486; 197.667±60.871 respectively. The most thin endometrium layer found in treatment with dosage P3 compared to control P0. From this study showed that there is no toxic effect on uterus and lymph function of of Nanas Bonsai (A. comosus var. microstachys L.) at different doses, so the plant is secure for consumption by the community.
