Cytotoxic and Antimicrobial Activities of Mushrooms and Medicinal Plant

Extractions of bioactive constituent from the Russula eburneureolata Hongo.stem bark of Xylocarpus gangeticus Parking. root and leaf of Walsura trichostemon Miq.and Parinari anamense Hancewith a polarity sequential extraction and maceration technique with hexaneethyl acetate and methanol.respectively.Crude extract was employed to evaluate the biological activity for their cytotoxic activity against human mouth carcinoma (KB) human small cell lung cancer (NCI-H187) and breast cancer (MCF-7)cancer cell lines tested using the Resazurin microplate assay (REMA).Antimycobacterial activity against Mycobacterium tuberculosis H37Ra strain (Anti-TB) using the Green Fluirescent Protein Microplate Assay (GFPMA)

This special project. The objective is to study the basic formulas and processes of rice crust production. Study the suitable amount of mushrooms in the production of rice crust. Study the suitable flavor in the production of rice crust Phoenix Mushroom. and study the quality changes during storage of Rice crust Phoenix Mushroom. from the study of the basic formula and the production process of rice crust the sensory evaluation results from 50 tasting testers. Found that formula 2 contains a mixture of steamed rice (Rice Sao Hai) steamed rice (Thai jasmine rice) and salt. The highest average rating. Study the suitable amount of mushrooms in the production of rice crust. Found that the formula with the amount of mushrooms: steamed rice 30% : 70% The highest average rating. The brightness (L*) red (a*) and yellow (b*) were 58.17±0.42 9.23±0.10 and 23.04±0.03 respectively. The aw value is 0.48±0.01. The moisture content is 2.60±0.01 percent. Study the suitable flavor in the production of rice crust Phoenix Mushroom. From the sensory tests of 3 flavors : Tom Yum flavors chilli flavors and pizza flavors showed that taste testers rated their liking for appearance color aroma flavor taste texture (Crispness) and overall liking Of the rice crust with the highest chilli flavor. Quality analysis chemical moisture protein fat ash fiber carbohydrate and peroxide values equal to 2.35±0.12 7.23±0.85 15.71±0.20 2.85±0.02 7.16±0.67 64.70±0.01 and 0.93±0.06 respectively. Study the quality changes during storage of rice crust Phoenix Mushroom. It was found that the brightness (L*) red (a*) and yellow (b*) increased from week 2 to week 6. The hardness value increases every week causing the breakage value to decrease. Moisture content not more than 4.0% and peroxide value not more than 30 mg. Equivalent Not exceeding the standards set by the industrial products. Therefore Phoenix Mushroom Rice Crust Products (chilli flavor). Therefore can be stored for more than 6 weeks

Drying an agricultural product with hot air (HA) method causes a long drying time and results in high specific drying energy consumption (SEC). The dried product has high shrinkage percentage and low rehydration. Therefore this research aims to develop dried shiitake mushroom using belt-conveyor combined microwave-hot air drying method (MHB). The shiitake mushroom was dried by MHB at microwave power of 300 W 400 W 500 W and 600 W and air temperature of 65 oC with air velocity of 0.3 m/s and recycled air of 80% and by the HA drying method at air temperature of 65 oC. The samples were dried until their final moisture content less than 11.1% dry basis. The drying kinetics SEC of drying process and quality of dried shiitake mushroom were evaluated. The quality of dried product was considered in terms of color shrinkage rehydration texture water activity and microstructure. The results showed that the shiitake mushroom drying using MHB gave higher drying rate than that of HA drying method leading to short drying time and resulting in low SEC. The drying rate of un-blanched shiitake mushroom was higher than that of blanched shiitake mushroom. Dried shiitake mushroom from MHB drying gave lower values in shrinkage percentages and hardness but higher rehydration and larger pore size than that dried by HA drying. However the color values (L* +a* and +b*) of dried shiitake mushroom in all cases were not significantly different. Meanwhile dried shiitake mushroom from un-blanched case gave lower values in shrinkage percentage and hardness but higher values in all colors and rehydration and larger pore size than those of blanched case.
