Introduction: Nelumbo nucifera Linn. Flowers health drinks currently are one of the popular demand globally in Thailand and all over the world. There are plenty of substandard or over claimed of antioxidant content labeled at health drink bottles. The consumers do not obtain enough health benefits anti-oxidant contents which are destroyed by heat during their production process. Methods: This study aimed to evaluate the optimization of extraction including water, 40 \% and 50\% ethyl alcohol using maceration and ultra-sonication method to obtain the highest antioxidant activity compared with DPPH, FRAP and ABTS methods were investigated including total phenolic and flavonoid contents by HPLC in different period of time. The analysis of acute toxicity in white wistar rats by oral administrating of Nelumbo nucifera Linn. flowers extract was testing for after 24 h and 14 d. Results: It was found that Nelumbo nucifera Linn. flower extract drink consisted of high contents of gallic acid, catechin and rutin by HPLC method. Nelumbo nucifera Linn flowers Highest Total Phenolic compound in Nelumbo nucifera Linn. flower extracts with sonicating with 50\% ethanol was 0.954639 {\textpm} 0.109672. Highest Total flavonoids in Nelumbo nucifera Linn. flower extracts macerating in 50 \% ethanol at day 5th was 1.100275 {\textpm} 0.777271.and the sonication with 40\% ethanol was 0.394283+/- 0.51175. Conclusions: The result of acute toxicity analysis showed no toxicity. Nelumbo nucifera Linn. flower extract drinks which are safe as a health drink for consumers. The further market analysis with sensory test should be essential for further research.

Introduction: Gastritis or /and gastric ulcers are one of the most common symptoms which occur in a large amount of the population. It results in a very high amount of medication expense. This study investigated the prevention and treatment of gastritis or /and gastric ulcer actions using white log mushroom (Lentinus squarrosulus, (Mont.). Methods: White wistar rats were induced with 100 \% absolute alcohol to be effective for gastritis and /or ulceration within rats. The gastric lesions of white wistar rats were investigated and calculated the lesions of stomach areas under microscopic method. The results were calculated and a comparative study among white wistar rats. Ulcer prevention and ulcer healing properties were administrated though a dose of 250 mg/kg of L. squarrosulus extract and L. squarrosulus compared with 50 mg/kg of Ranetidine. Results: It was found that Lentinus squarrosulus, (Mont.) consisted of Beta-glucan was the active ingredient creating a healing effect. It showed a result of 100\% healing effect in gastritis and/or ulcers in which it had similar healing effects between extracted solutions of white log mushroom (250 mg/kg body wt.) The healing activity also showed the equivalent effect compared to Ranetidine 150mg. Conclusions: Extracted solution of white log mushroom showed prevention and treatment efficacy in gastritis and/ or ulcer are equivalent to Ranetidine 150 mg. A similar dose of 250 mg/kg of L. squarrosulus extract and L. squarrosulus snack can prevent and heal ulcers and is more effective than Ranetidine.

Aim/Background: The objectives of the study were to determine total phenolic contents, flavonoid contents, antioxidant activities and assess acute toxicity of torch ginger (Etlingera elatior Jack.) inflorescent hydroethanolic extract. Methods: The analysis of total phenolic contents, total flavonoid contents and antioxidant activities were analyzed spectrophotometrically using micro-titer plate reader. With regard to acute toxicity assessment, Wistar rats were fed with a single dose of torch-ginger either 1.0, 1.5 or 2.0 g extract/kg body weight in comparison with control group. Results: Total phenolic contents, flavonoid contents of the extract were 0.17\±0.02 mM gallic acid equivalent/g extract and 0.30\±0.01 mM quercetin equivalent/g extract, respectively. The antioxidant evaluation using DPPH radical scavenging assay, FRAP assay and ABTS radical scavenging assay were 0.14\±0.08 mg/ml (EC50), 0.13\±0.01 mmol Fe2+ equivalent/g extract and 0.30\±0.12 mM trolox equivalent/g extract, respectively. According to acute toxicity, no mortality or bizarre behavior had been observed throughout 14 days. Clinical chemistry including blood glucose, AST, ALT, BUN, creatinine, total cholesterol, triglyceride, HDL, LDL, total serum protein, albumin, globulin and total bilirubin were in normal ranges and comparable to the control (p\<0.05). In conclusion, phenolic compounds and flavonoids of torch-ginger could be measured and indicated the quality of the extract as well as antioxidant activities. Regarding acute toxicity assessment, the extract was safe for experimental animals up to 2.0 g extract/kg body weight. Conclusion: Torch-ginger extract exhibited high amounts of phenolic contents, flavonoid contents, antioxidant activities and was safe in animal model.
