This research aims to study phytochemicals and potential of Mapok (Parinari anamense Hance) extracts to inhibit germination and growth of Barnyard grass (Echinochloa crus-galli) a common weed in the rice fields. Organic solvents extracted the part of fruits barks and leaves of Mapok included hexane ethyl acetate and methanol. Crude extracts compose of fruit hexane extract fruit ethyl acetate extract fruit methanol extract bark hexane extract bark ethyl acetate extract bark methanol extract leaves hexane extract leaves ethyl acetate extract and leave methanol extract. Crude extracts were tested of phytochemical tested of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition of Barnyard grass. Leaves ethyl acetate extract showed highest inhibit germination and growth of Barnyard grass The leave ethyl acetate extract was separated by column chromatography to yield nine fractions (F1 – F9 fraction) and tested inhibit germination and growth repeating. The results showed that 1. The crude ethyl acetate extracts from the bark of Mapok at a concentration of 3000 ppm showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition. 2. Fraction F8 of leaves ethyl acetate extract showed the highest inhibited percentage of germinating inhibition root length inhibition stem length inhibition and dry weight inhibition.

The research project on The potential of Siphonodon celastrineus Griff traditional medicinal plants of Thailand for treatment from local wisdom knowledge lead to the development of sustainable use with the objective of studying the botanical phytochemical and biological activity of the Siphonodon celastrineus to create confidence in the use of S. celastrineus in herbal medicine by using the bark leaves and fruit of the S. celastrineus to extract with 3 types of solvents. Each of hexane ethyl acetate and methanol respectively from low to high polarity. All nine extracts will be extracted. Preliminary examinations for phytochemistry Antioxidant activity by DPPH radical scavenging assay and quantitative determination of phenolic compounds by Folin-Ciocalteu method and antimicrobial activity were tested. The research found that. 1. The extract of the results of the methanol layer of the S.celastrineus shows a reduction in the amount of 11-diphenol-2-picrylhydrazyl (DPPH) had the highest EC50 equal to 31 mg/ml. The amount of phenol compounds found that the extracts from the methanol extract of S. celastrineus contain the amount of phenol. The highest concentration of 95.23 mg GAE / g dw 2. Extract from the bark of the S. celastrineus with methanol showed the best inhibition of the growth of Vibrio paraheamolyticus with the MIC value of 15.60 mg/ml. The extracts of the S. celastrineus leaf extracts with hexane showed the best inhibition of the growth of Vibrio cholerae with the MIC value equal to 31.25 mg/ml and leaf extracts with ethyl acetate showed the best inhibitory effect on the growth of Vibrio cholerae with a MIC value of 31.25 mg/ml and the extract of the fruit with ethyl acetate to inhibit the growth of Vibrio paraheamolyticus most with MIC equal to 15.60 mg/ml.

The Potential of food crops in the Phraek Nam Daeng community Amphawa Samut Songkhram province for food security and sustainable use of biodiversity Local plants were tested phytochemical composition antioxidant activity antimicrobial activity and nutritional analysis. The results showed that phytochemical composition of local plants most of the cardiac glycosides tannins and antraquinones. Acanthus is the highest antioxidant activity Kloe and Hnampugda respectively. Antimicrobial activity of both Gram-positive bacteria. Gram- negative bacteria and yeast is very low.The nutritional value is the maximum on each side The amount of water is Phak Protein is Acanthus Fat is Hnampugda fiber is Kloe and carbohydrate is Hnampugda.

The study used the bark leaves and fruit of Ficus hispida Linn to separation by Maceration and sequential extraction method with hexane ethyl acetate and methanol to crude extracts. Crude extracts were assessed for their antioxidant activities tested using DPPH radical scavenging assay total phenolic contents tested using the Folin–Ciocalteu method cytotoxic activity against oral cavity cancer (KB) human small cell lung cancer (NCI-H187) and breast cancer (MCF-7) cancer cell lines tested using the resazurin microplate assay (REMA). The results showed that 1. Crude methanol extracts from the fruit exhibited free radical scavenging effect on the DPPH assay with IC50 value of 27 g/ml with the total phenolic contents value of 102.39 mg GAE/g dw of standard BHT. 2. Crude hexane extracts from the bark showed highest inhibited the growth of Vibrio paraheamolyticus crude ethyl acetate extracts from the bark showed highest inhibited the growth of Streptococcus mutans ATCC 27175 and crude methanol extracts from the leaves showed highest inhibited the growth of Vibrio cholerae most with MIC value of 7.80 g/ml. 3. Crude ethyl acetate and methanol extracts from F. Hispida exhibited inhibitory effect against oral cavity cancer (KB) human small cell lung cancer (NCI-H187) and breast cancer (MCF-7) cancer cell lines. These data support traditional uses of F. Hispida in folk medicine

The objective of this research was to determine the formulation of soap for carving operations and study the satisfaction of developed carved-soap by carving person. There were 3 basic formulas of the soap e.g. olive oil formula (formula 1; 500 ml olive oil 60 g sodium hydroxide and 140 ml water) coconut oil formula (formula 2; 200 ml coconut oil 34 g sodium hydroxide and 80 ml water) and glycerin formula (formula 3; 200 g glycerin and 5 g sodium hydroxide). The basic formula 3 showed the highest satisfaction scores from carving person when compared with other formulas. The next experiment was to find the optimal temperature for heating the mixtures in the range of 40-60oC. The results showed that the temperature of 45oC was the best treatment for heating three types of soap mixtures. Moreover the formula 3 soap received the highest satisfaction scores ( X = 4.21-4.53) from carving person which had the good appearance exquisite styles shape and proportion right. There was no crack no visible of mold growth and soap powder on the product after caving operations. The satisfaction of 52 carving persons between the general soap and developed carved-soap for carving operations was studied using 5-point rating scales. The satisfaction scores of softness stickiness and aroma were significant different (p<0.05) between two types of soap. However the dryness/hardness silkiness color painting property and overall quality scores were not different. The suitable shape of soap for carving operations was a round shape followed by square shape oval shape and heart shape respectively.
