Effect of Betulinic acid Extraction from Guava (Psidium guajava Linn.) Leaves Against Human Cholangiocarcinoma Cells.

ABSTRACT:

Background

Betulinic acid (BA), a pentacyclic triterpene glycoside extract from guava (Psidium guajava Linn.) leaves, displays a variety of biological activities which exhibit cancer therapeutic properties associated with cancer growth inhibition in various kinds of human cancer cells including brain, breast, colorectal, cervical, lung and prostate gland. However, the effects on human cholangiocarcinoma cells have not previously been reported. Current study, we evaluated the activity of BA against human cholangiocarcinoma (HuCCA) cells.

Methods

The cytotoxicity analysis was measured by using MTT assay on HuCCA and BHK-21 cells. Analysis of apoptosis was evaluated by using staining with Hoechst 33342 and quantitative real-time PCR.

Results

The BA (50-800 µg/mL) significantly reduced the viability of HuCCA cells in a dose-dependent action with 50% inhibitory concentration (IC50) of 92.45 µg/mL at 24 h. It also induced apoptosis signaling pathway, such as nuclear chromatin condensation and fragmentation. Quantitative real-time PCR analysis demonstrated that BA increased p53, Bax and caspase-3 expression whilst it decreased Bcl-2 expression in the HuCCA cells in a dose dependent manner.

Conclusion

BA can inhibit the HuCCA cell viability and induce apoptosis of neoplastic cells. This study indicates that BA has effective treatment for cholangiocarcinoma in vitro. Consequently, BA may be used as a novel therapeutic agent for the treatment of cholangiocarcinoma in the future.

Project description:The Brazilian guava processing industry generates 5.5 M Mg guava waste year(-1) that could be recycled sustainably in guava agro-ecosystems as slow-release fertilizer. Our objectives were to elaborate nutrient budgets and to diagnose soil, foliar, and fruit nutrient balances in guava orchards fertilized with guava waste. We hypothesized that (1) guava waste are balanced fertilizer sources that can sustain crop yield and soil nutrient stocks, and (2) guava agroecosystems remain productive within narrow ranges of nutrient balances. A 6-year experiment was conducted in 8-year old guava orchard applying 0-9-18-27-36 Mg ha(-1) guava waste (dry mass basis) and the locally recommended mineral fertilization. Nutrient budgets were compiled as balance sheets. Foliar and fruit nutrient balances were computed as isometric log ratios to avoid data redundancy or resonance due to nutrient interactions and the closure to measurement unit. The N, P, and several other nutrients were applied in excess of crop removal while K was in deficit whatever the guava waste treatment. The foliar diagnostic accuracy reached 93% using isometric log ratios and knn classification, generating reliable foliar nutrient and concentration ranges at high yield level. The plant mined the soil K reserves without any significant effect on fruit yield and foliar nutrient balances involving K. High guava productivity can be reached at lower soil test K and P values than thought before. Parsimonious dosage of fresh guava waste should be supplemented with mineral K fertilizers to recycle guava waste sustainably in guava agroecosystems. Brazilian growers can benefit from this research by lowering soil test P and K threshold values to avoid over-fertilization and using fresh guava waste supplemented with mineral fertilizers, especially K. Because yield was negatively correlated with fruit acidity and Brix index, balanced plant nutrition and fertilization diagnosis will have to consider not only fruit yield targets but also fruit quality to meet requirements for guava processing.

Project description:BackgroundGuava (Psidium guajava Linn.) has been traditionally used in the treatment of a wide range of diseases due to its rich content of secondary metabolites.AimThis study was aimed to evaluate the effect of altitude and solvent systems on guava leaves crude extract's phenolics and flavonoid content, antioxidant, antimicrobial, and toxicity nature.MethodsGuava leaves were collected from three different geographical locations in Nepal while solvents with an increasing polarity index were used for extraction. The yield percentage of extracts was calculated. Total Phenolic Content, Total Flavonoid Content, and antioxidant activity were determined by the Folin-Ciocalteu method, Aluminium chloride colorimetric method, and DPPH (2,2'-Diphenyl-1-picrylhydrazyl) assay respectively. The quantification of fisetin and quercetin was performed using the HPLC with method validation. The antimicrobial activity of the extracts was tested against bacteria and fungus isolated from spoiled fruits and vegetables and identified through 16s and 18s rRNA sequencing. Finally, Brine Shrimp Lethality Assay (BSLA) was used for testing the toxicity of the extracts.ResultsThe phenolic and total flavonoid content was found to be higher in ethanol extract (331.84 mg GAE/g dry extract) and methanol extract (95.53 mg QE/g dry extract) from Kuleshwor respectively. Water extract of guava leaves from Kuleshwor (WGK) did not show significantly different antioxidant activity when compared to methanol and ethanol extracts. Fisetin and quercetin were higher in WGK (1.176 mg/100 g) and (10.967 mg/100 g) dry extract weight respectively. Antibacterial activity against food spoilage bacteria was dose-dependent and found to be highest for all the extracts from different solvents and altitudes at higher concentrations (80 mg/ml). Similarly, methanol and ethanol guava extracts from all locations showed antifungal activity against Geotrichum candidum RIBB-SCM43 and Geotrichum candidum RIBB-SCM44. WGK was found to be non-toxic.ConclusionOur study concludes that the antioxidant and antimicrobial activity of WGK was found to be similar statistically to that of methanol and ethanol extracts of Bishnupur Katti and Mahajidiya. These results suggest the possibility of using water as a sustainable solvent to extract natural antioxidant and antimicrobial compounds which can further be used as natural preservatives to extend the shelf life of fruits and vegetables.
