Limonia Acidissima

Wood apple botanically identified as Limonia acidissima is an indigenous fruit with amazing nutritional and health benefits. Reports from traditional literature of Ayurveda and Siddha portrays the medicinal properties of this fruit. The scooped pulp of the ripe fruit is consumed as such or it can be made into different recipes. But inclusion of this fruit in our diet is not found as a regular practice. Many people are still unaware of the benefits of this fruit. Hence, this study was taken up to unravel the biological potencies of this fruit by conducting in vitro experiments. Phytochemicals such as alkaloids, flavonoids, phenols, saponins and ascorbic acid have been estimated. Anti-inflammatory activity of the aqueous extract of fruit pulp combined with outer rind has been evaluated through inhibition of albumin denaturation. Among the 5 different concentrations (200, 400, 600, 800, 1000 µg/ml), at 1000 µg/ml wood apple has shown 74.55% of protein denaturation inhibition which was compared with standard Diclofenac sodium. Antioxidant capacity of the extract was expressed as mg/100g ascorbic acid equivalent through phosphomolybdenum assay. Dose dependent increase in the antioxidant activity was observed. About 8 different concentrations of the aqueous extract of L. acidissima were evaluated for their cytotoxic activity on MCF 7 cell line. At a concentration of 1000 µg/ml, the extract has shown 93.43% of cytotoxicity and 6.57% of cell viability. Apoptotic induction was evaluated and confirmed by the formation of DNA ladders through DNA fragmentation assay. GCMS analysis of wood apple fruit pulp and rind revealed the presence of several phytochemicals among which many of them had therapeutic activity reported earlier.

Background: The use of plants for healing dates back to very remote times. Nowadays with the accession of new diseases plants are increasingly used for the formulation of new drugs able to overcome the many diseases (cancer, atherosclerosis) often caused by the disorder of the system prooxidant/antioxidant. Aim/Objective: On the strength of this observation, the research of an antioxidant plant is essential, hence the aim of this study, which is to determine the antioxidant activity of the stalk and the fruit of Solanum aethiopicum L. Methods: The fruits and stalk were washed, cut into fine slats, then dried in the incubator for three days and finally crushed into powder. An extraction by decoction with ethanol (stalks and fruits) and water (fruit) was subsequently carried out to obtain three extracts (ethanol and water). Antioxidant activity was evaluated through the FRAP method, and the trapping of radical DPPH. Results: For the FRAP method, at the highest concentration (1 mg/ml) the aqueous extract of the fruit (74.84±2.97%) has a higher reducing power compared to those of the ethanolic extracts of the fruit (70.15 ± 5.72%) and the stalk (49.85 ± 2.11%). These reducing powers, although significant, remain lower than those of tannic acid (89.95±0.007%). And finally, for the DPPH method, the aqueous extract of the fruit is more effective in reducing free radical DPPH with a IC50= 162±33 µg/ml, follow up by ethanol extract from the stalk (IC50= 360± 90 µg/ml) and finally ethanol extract from the fruit (IC50= 362.5± 23.5 µg/ml). These results confirm the in vitro antioxidant activity of the studied parts of Solanum aethiopicum. Conclusion: Prospective studies could focus on acute and subacute toxicities and the determination of the molecules responsible for the activity.

The methanol extract of the whole plant of Blumea lacera (Burn.f.) DC. (BLME) has been subjected to preliminary screenings for phytoconstituents and antipyretic, analgesic and anti-inflammatory activities. Antipyretic activity was assessed by the yeast-induced hyperthermia in mice. The analgesic property was evaluated by formalin-induced writhing test. Acetyl salicylic acid (ASA) was used as standard for in-vitro anti-inflammatory activity test. In yeast-induced pyrexia, the crude extract demonstrated a significant (p=0.05) reduction in body temperature of mice after elevation by the administration of yeast. These effects were pronounced at the 2nd and 3rd h of post-treatment with the extract. BLME exhibited a dose-dependent analgesic activity with 39.13% and 56.52% protection at 200-and 400-mg/kg, b.w., respectively as compared to 76.09% revealed by the standard diclofenac sodium. In the anti-inflammatory test, the crude extract at 400 ?g/ml displayed 62.40% inhibition of protein denaturation whereas standard acetyl salicylic acid exhibited 76.74% inhibition. Results of the preliminary phytochemical screenings demonstrated the presence of alkaloids, flavonoids and triterpenoids in the extract. DOI: http://dx.doi.org/10.3329/dujps.v13i1.21863 Dhaka Univ.

Dental caries and periodontal diseases are among the most important global oral health problems, although conditions such as oral and pharyngeal cancers and oral tissue lesions are also significant health concerns. Pomegranate extracts have been used for centuries in traditional medicine to confer health benefits in a number of inflammatory diseases, microbial infections and cancer. The anti-inflammatory activity of pomegranate extract was evaluated by protein denaturation assay, and the results were read spectrophotometrically. Denaturation of proteins is a great‐ documented cause of inflammation. As a part of the investigation on the mechanism of the anti-inflammatory activity, the ability to extract to inhibit protein denaturation was studied. It was effective in inhibiting heat induced albumin denaturation at different concentrations as shown in Table 1. Maximum inhibition, 70.12±1.12% was observed at500µg/ml. IC50 value was found to be 105.35±1.99µg/ml. Aspirin, a standard anti-inflammatory drug showed the maximum inhibition, 77.12±1.42% at the concentration of 200µg/ml. Hence it can be concluded that pomegranate extract has anti-inflammatory property and also can be used in products such as toothpaste and mouth wash etc.

Various strategies have been employed in the treatment and management of Salmonella infection however, Salmonella strains have gained resistance to antibiotics. This study was to determine in vitro anti-Salmonella activity of Boerhaavia diffusa leaf extract against clinical isolate of Salmonella typhi and Salmonella typhi ATCC 14028. The aqueous and ethanol extracts of B. diffusa were studied for their antibacterial activity against pathogenic Salmonella typhi. This study was carried out between April and September 2018. The in vitro antibacterial activity was performed by agar well diffusion method and broth dilution using spectrophotometric method and the results were expressed as the average diameter of zone of inhibition of bacterial growth around the well and optical density respectively. It was observed that aqueous extract exerted slightly higher activity than ethanolic extract as revealed by the mean diameter of zone of inhibitions at a concentration of 200 mg/ml, the aqueous extract had 35.21±0.47 mm (Salmonella typhi ATCC 14028) compared with ethanol extract 26.41±0.32 mm (clinical). However, in the broth dilution method, ethanol extract significantly (p=0.05) reduced the cell, at 48 hours, the optical density of clinical isolate of S. typhi treated at concentration of 200 mg/ml of extract was 0.47±0.02 nm while at the same concentration of extract, aqueous extract had an optical density of 0.52±0.11 nm respectively. The phytochemical assay revealed that tannin (5.18±0.02 mg/g) and quinone (8.45±0.13 mg/g) in ethanol extract was significantly (p=0.05) higher than aqueous extract while saponin (14.18±0.06 mg/g) was higher in the aqueous extract. The ethanol and aqueous extracts of leaves of B. diffusa whole plant exhibited significant antibacterial activity against both clinical and typed Salmonella typhi. Therefore, the plant extract could be used for the treatment of Salmonellosis, however, the in vivo studies is needed to ascertain the safety of the extract.
