Callistemon citrinus (Curtis.) (Family- Myrtaceae) is a popular evergreen shrub in Bangladesh. In the present study, leaves of this plant have been assessed comprehensively for free radical scavenging, thrombolytic and membrane stabilizing activities.The were collected, powdered extracted with methanol. The extract was then concentrated successively fractionated into petroleum ether, carbon tetrachloride, chloroform aqueous soluble fractions. extractives investigated activities.In case 1,1...

Adulteration of foods has become a national issue. The problem is not only ignoring the human rights for safer food but also endangering public health seriously with numerous acute and chronic diseases. Our future generation will be affected vulnerable physical mental growth inflicted by adulteration. This paper describes impact consumption adulterated on roles concerned authorities to eradicate it. key objective this blame or undermine anyone. We intend inform current scenario adulteration...

Abstract A study was undertaken to determine the contents of trace metals in 60 topsoils and 80 brinjal fruits samples from a famous brinjal-producing area Bangladesh using atomic absorption spectrophotometer. The also looked at soil pollution levels, dietary intake nutritionally important elements, human health risks toxic induced by dermal exposure consumption brinjal. content Pb, Ni, Cd, Cu, Fe, Mn, Zn harvested farmer′s fields ranged 0.204–0.729, 0.031–0.212, < 0.010–0.061,...

Diospyros blancoi, a member of the Ebenaceae family, has been broadly used in traditional medicine. This study was carried out to assess antidiarrheal, hypoglycemic, analgesic and antibacterial activities methanol extract barks leaves D. blancoi. The methanolic extracts blancoi at dose 400 mg/kg inhibited 29.22% (p < 0.01) 19.13% 0.05) diarrheal defecation, respectively. did not show significant activity acetic acid-induced writhing method. However, exhibited notable with 40.88% 0.001)...

Background Piper chaba is a common plant in Bangladesh. It enriched with many important biologically active compounds and popular for traditional healing. Method The methanol extract of the root P. was fractionated into n -hexane ethyl acetate soluble fractions. fraction subjected to various chromatographic techniques isolate pure compounds. structures were elucidated aid UV, IR, NMR, including 1 H, 13 C, DEPT-135, COSY, HSQC, HMBC, spectroscopy, LC-MS. isolated cytotoxicity assay using HeLa...

A total of four compounds namely, lupeol (1), betulinaldehyde (2), betulinic acid (3) and stigmasterol (4) were isolated from the stem extract Dillenia indica Linn. The structures (1-4) established by extensive spectroscopic studies. crude methanolic extracts its n-hexane, carbon tetrachloride, dichloromethane chloroform soluble partitionates demonstrated weak antimicrobial activity against a wide range Gram-positive Gram-negative bacteria fungi. extractives revealed significant cytotoxic...

The antimicrobial activity of methanol extracts 17 plant species Bangladesh was evaluated by the agar disc diffusion method. Among those, eight exhibited potent against a wide variety Gram positive and negative bacteria fungi at concentration 400 μg /disc.Key words: Antimicrobial activity, Disc method.DOI = 10.3329/dujps.v7i1.1213Dhaka Univ. J. Pharm. Sci. 7(1): 23-26, 2008 (June)

In this study, five compounds, lupeol (1), epilupeol (2), β-sitosterol (3), stigmasterol (4) and p-methoxybenzaldehyde (5) were isolated from the petroleum ether dichloromethane fractions of a methanolic extract stem bark Delonix regia. Antimicrobial screening different extracts (15 μg mm-2) was conducted by disc diffusion method. The zones inhibition demonstrated ether, carbon tetrachloride ranged 9-14 mm, 11-13 mm 9-20 respectively, compared to kanamycin standard with zone 20-25 mm. brine...

Drynaria quercifolia L. (Family- Polypodiaceae) is a fern grows in Bangladesh used traditional healing by the Garo tribe of Mymensingh district. In current study, rhizomes and fertile foliage fronds this plant have been investigated comprehensively to assess their vitro membrane stabilizing, thrombolytic antioxidant properties. Rhizomes D. were collected, dried, powdered extracted with methanol. Later on, crude methanol extracts parts fractionated into petroleum ether, carbon tetrachloride,...

Wendlandia tinctoria var. grandis (Roxb.) DC. (Family: Rubiaceae) is a semi-evergreen shrub distributed over tropical and subtropical Asia. The present research intended to explore the pharmacological potential of stem extract W. tinctoria, focusing on antioxidant, hypoglycemic, antidiarrheal properties, isolate various secondary metabolites as mediators such activities. A total eight phenolic compounds were isolated from dichloromethane soluble fraction this plant, which characterized by...

Abstract The simultaneous analysis of α‐HCH, β‐HCH, γ‐HCH, HCB, p , ′‐DDD, ′‐DDT, ′‐DDE, o mirex, dieldrin and 62 chlorobiphenyl congeners on two parallel capillary GC columns different polarity is described for nine Mediterranean fish species. Ten commercially available with stationary phases completely characterized in respect their PCB elution patterns were considered dual‐column GC‐ECD analysis. combination a 60 m × 0.25 mm i.d. column coated μm film 50% diphenyl dimethylsiloxane series...

The present study describes the ethnobotanical, phytochemical, and toxicological evaluations of Xanthium strumarium L. growing in Bangladesh. In toxicity evaluation on rats, methanol extract seedlings showed mortality, while both seedling mature plant extracts raised serum alanine transaminase aspartate values produced significant abnormalities histopathology liver kidney rats. On other hand, aqueous soluble fraction (LC50 = 0.352 µg/mL) crude 0.656 demonstrated brine shrimp lethality...
