Piper Betel has been used as a medicinal herb in Thailand for a long period. Not only consumption but Piper Betal also has been used for religious belief and ritual. However the piper leave should be in the good condition without any defect. As a result there are numerous fall-grade leaves to be get rid of from agriculture. Increasing the value-added of this by- product can increase the income. Extraction of bioactive compounds by using alembic is uncomplicated and green without any solvent is required. Two products come out from this process the first one is an essential oil which is expensive. The second product is hydrosol. The piper hydrosol still contained various phytochemicals. In this study total phenolic content was investigated and was found to be in the range 31.16-73.71 GAE mg/g. Total antioxidant capacity was also studied using the DPPH method. The antioxidant activity was 0. 37▁(+)0.11 mg ascorbic acid equivalent/ ml hydrosol. However the piper hydrosol cannot inhibit P.ance S.aureus and S.epideminis. To sum up the piper hydrosol can be used as an ingredient for antioxidant cosmetics rather than antibacterial skincare.

The survey team aimed to develop online marketing on Plantago Major Linn. to Promote Sustainable Economy at Ban Muang Charoenraj Agricultural Safety Community Nhan Province. Ban Muang Charoenraj community is an agricultural community enterprise which has been recently established for two years and begun to cultivate and produce Plantago major L. products and need to develop a better online marketing approach for their interesting products. The research team therefore introduced the new approach including the choice of plant stage selection raw material preparation making fermented Plantago major L. extract determination of the properties of the plants that are anti-inflammatory and antioxidant and their antimicrobial activity. The plant extracts were thus developed as a key ingredient in facial creams because of their such good characteristics helping to promote the channel of online marketing. It was on the basis that Ban Muang Charoen community has the plants good raw materials good products one already made online media system of Facebook therefore the online media system was suitably developed further and used to be a medium for people to have the opportunity to know more about such products. The work that the research team relied on “Smart Gold principles” which can analyze online marketing practices for two stores. It helped create an opportunity to develop the store to generate more income to be able to improve and develop sales management in the future obtain more page views and introduce the community get involved in selling a wide variety of products online as well as transferring the utilization of Plantago major L. from the research team to the community. In the analysis it was found that it was necessary be able to increase sales by at least 20 percentages measurable attainable consistent with reality be able to learn and implement in no more than three months. In addition 2) obtain management guidelines that need to be supplemented further; there must be a promotion to control the quality production of Plantago major L. in the community. Quality and refrain from using pesticides. By promoting the provision of a one-stop service to the community the online marketing will be a source that can manage the linkage of raw materials to the buyers. Chemicals related to herbal extraction process and the materials for making cosmetic products would be set for creating ease of operation for customers to be able to track budget used and to easily manage the product quality along the way with a quick and reliable delivery service. It is necessary to encourage a clear analysis of the business plan of each store. From these necessities of the research to promoting online marketing channels for the Ban Muang Charoenraj Agriculture Enterprise Community a communication channel and promotion for customers can generate income for the anywhere anytime without limitation suitable for the current situation.

The research team had thought of studying the properties of natural fermented Maieng extract as an important antioxidant substance in cosmetics. to transfer to the Sakadee community Nan Province. The research had started at the development of a natural fermentation process studied the extraction process yielding important substances from natural Miang fermentation and evaluated the antimicrobial activity and anti-oxidation of bioactive extracts. The outcome studies were transferred including the extraction process of bioactive compounds and formulations in skin cream cosmetics. It was demonstrated that natural fermentation by adding clean disinfected water or fermentation with a stock of Lactic acid bacteria isolated from Miang fermented water in anaerobic conditions for 2 weeks the efficiency and characteristics of fermentation were not significantly different. In the process of extracting bioactive substances with ethanol by soaking the extracts with water and virgin coconut oil with the maceration method at room temperature and shaking in 80% ethanol for 3 hours resulted in a high content of antioxidant properties. In addition the developed approach influenced the characteristics of fermented Miang meat well accepted by the users. This fermented Miang extract was acceptably used to make fermented Miang products for further sale. With the potential of Miang fermented extract in antimicrobial activity therefore the extract has been made a face cream product and tested for user acceptance. From preliminary testing it was found that the facial product with the fermented Miang extract to be satisfactory and did not cause allergic reactions. It had the ability to reduce wrinkles could clear face and transferred to the community focusing on the needs of users in the community. The community could make such face cream products and processed the commercial Miang extract cream that are acceptable to general consumers.

Premna trichostoma Miq. (Lamiaceae) mainly distribute in Asia including Thailand. Folk healers use this plant to treat fever as a juice splash and bathe. The aims of this study are to evaluate the quantity of active constituents and antioxidant activity of P. trichostoma leaf extract. Total phenolic compounds were determined using Folin-Ciocalteu method. Total flavonoid contents were determined by Aluminum chloride method. The amount of apigenin and kaempferol contents were analyzed by high performance liquid chromatography (HPLC). In addition the antioxidant activity was evaluated by DPPH and ABTS assay. The results showed that total phenolic contents total flavonoid contents and the amount of apigenin and kaempferol of P. trichostoma leaf extract was 46.45±15.30 mg GAE/g extract 25.48±2.02 mg CE/g extract 11.16±0.04 and 4.54±0.08 µg/g extract respectively. The IC50 values from the DPPH and ABTS assay was 117.50±1.22 and 36.14±1.53 µg/ml respectively. This study shows the antioxidant properties and active constituents of P. trichostoma leaf extract which indicates the potentials for further development of this plant

The purpose of this research was to analyze carotenoid content anthocyanin content phenolic compound content and the antioxidant activity by 2 2-diphenyl-1-picrylhydrazyl scavenging capacity (DPPH) and 1 10-Phenantroline (Phen). In the 3 varieties of corn milk which were the Queen Ruby Siam strain (Purple corn milk) (White corn milk) Sweet strain (Yellow corn milk). It was found that the samples of 3 types of corn milk have total carotenoid content were 0.45+0.00 0.29+0.02 and 0.68+0.00mg/l respectively. Anthocyanin content measured by pH-differential method were 2.86+0.01 1.71+0.03 and 0.80+0.01 mg/l respectively. The total amount of phenolic compounds were 12.00+0.02 10.05+0.00 and 8.62+0.09 mg/l respectively. The ability to resist free radicals by DPPH method were equal to 96.50+0.10 47.10+0.01 and 60.91+0.08 respectively. The antioxidant activity using Phen method were 133.98+0.76 111.17+0.48 and 86.61+0.98 mg/l respectively.
