The Hemerocallis accessions is widely consumed as nutritious vegetable and traditional medicine in eastern Asia and used as an ornamental flower worldwide. Compared with most other horticultural products, its flower is richer in polyphenols, flavonoids, carotenoids, and anthocyanins. Therefore, the flower has strong antioxidant activity that inhibits cancer cell proliferation, which could used for health and pharmaceutical purposes. The flavonoids composition and distribution in the flowers, and the content varied between different accssions is still unclear. In this context, eight flavonols, two flavones, and two anthocyanins were determined in Hemerocallis flower by high-performance liquid chromatography (HPLC) coupled with photodiode array and mass spectrometric detectors. Rutin was the most abundant flavonols and cyanidin 3,5-glucoside and cyanidin 3-rutinoside were the major anthocyanins in Hemerocallis tepals, resulting in flower petal coloration, and their content in the petal was higher than that of the sepal. Hierarchical cluster analysis grouped the 42 accessions into four groups, and they were significantly different (p < 0.05) from each other in the ten significant compounds by One-way ANOVA. Overall, the qualitative and quantitative analysis of flavonoid constituents in six floral parts of 42 Hemerocallis accessions were elucidated, which could be helpful for the food and pharmaceutical industries, and lay the foundation for the Hemerocallis flower color research.

Empowerment of Horticultural Farmers: The Case of Werdhi Guna Farmer Group of Pempatan Village, Rendang District, Karangasem Regency Pempatan Village, Rendang District, Karangasem Regency has great vegetable potential, but farmers have not been able to utilize the condition well. There needs to be empowerment to increase farmer's income and farmer's prosperity. The purpose of this research is to know (1) horticultural potential (2) process of empowering horticulture farmers. This research used qualitative and quantitative analysis methods. The results showed the potential of vegetable horticulture (Olericulture) in Werdhi Guna Farmer Group with the achievement of score 4.2 with the good category meaning that Werdhi Guna Farmer Group has a tropical area and is suitable for horticultural cultivation. Horticultural plants grow with maximum results, seen from the fact that vegetable crops are fertile although obstacles still persist such as the limited availability of water for watering plants. As for the empowerment of farmers, it is of good category with averageachievement score of 3.9 meaning that the farmers play an important role in horticultural cultivation and the importance of government roles given to Werdhi Guna Farmer Group in enhancing knowledge or innovation in agriculture. In this research, it is suggested that farmers in Werdhi Guna Farmer Group are expected to be able to increase their horticultural products in order to be able to compete in the market to improve farmer's welfare, and of course to promote vegetable farming (Olericulture) and the government should pay more attention to horticultural farmers and provide support in the form of aid and training that can make them able to increase their farming.

AbstractThis study presents the results obtained from qualitative and quantitative analysis of gallic acid from hydro-alcoholic extracts (methanol, ethanol) of plants from Plantae regnum. Plant qualitative analysis was performed using a novel mass spectrometric (MS) method based on fully automated chip-nanoelectrospray ionization (nanoESI) high capacity ion trap (HCT) while quantitative analysis was carried out by high performance liquid chromatography (HPLC). These methods were applied to Alchemilla vulgaris — common lady’s-mantle (aerial part), Allium ursinum — bear’s garlic (leaves), Acorus calamus — common sweet flag (roots), Solidago virga-aurea — goldenrod (aerial part). Obtained results indicated that methanol extracts (96%, 80%) have a gallic acid content ranging between 0.0011–0.0576 mg mL−1 extract while the ethanol extracts (96%, 60%) exhibit a gallic acid concentration that varies between 0.0010–0.0182 mg mL−1 extract.
