From South America to Southeast Asia, these fruits have been used for a wide variety of ailments, including cough, diabetes, dysentery, inflammation and ringworm. These same fruits are also used to make many food products. Based on information regarding ethnomedical use, known phytochemistry, fruit color, popularity as edibles and availability, the fruits of several edible species from the subtribe Eugeniinae have been selected for phytochemical analysis in an attempt to discover new antioxidants. The fruits of six species in this group have shown a strong antioxidant activity in the 1,1-diphenyl-2-picrylhy-drazyl chemical assay. The UV absorbance spectrum of the most active compound in Eugenia uniflora L. indicates that it is a flavonoid. Polyphenolic compounds like flavonoids have an enormous range of biological activity and are known to inhibit oxidative damage in vivo better than the classical vitamin antioxidants. In plants, they protect against lipid peroxidation and UV damage that can affect tropical fruits growing under severe conditions including high heat and intense sunlight. http://hdl.handle.net/10125/297 Title: Ethnobotany of the genus Piper (Piperaceae) in Thailand <br/> <br/>Author(s): Chaveerach, Arunrat; Mokkamul, Piya; Sudmoon, Runglawan; Tanee, Tawatchai http://hdl.handle.net/10125/251 Title: Ethnobotanical Study of Rice Growing Process in Northeastern Thailand <br/> <br/>Author(s): Mokkamul, Piya <br/> <br/>Abstract: Thailand is a developing country that relies heavily on rice agriculture. Photographic techniques are an easy and efficient method for studying human activities, culture, traditions, ethnobotany, and ethnoeconomy. In this paper, photos are used to provide an ethnobotanical description of the rice growing process of rice farmers in Northeast Thailand, from preparing the rice fields to harvesting the rice. “One picture can speak a thousand words.” <br/> <br/>Description: Photo essay http://hdl.handle.net/10125/250 Title: Conservation Status of Maianthemum Species in the Hengduan Mountains: A Case Study Analyzing the Impact of New Policies on Wild Collected Plant Species <br/> <br/>Author(s): Ying, Meng; Yongping, Yang; Weckerle, Caroline S. <br/> <br/>Abstract: Maianthemum G. Weber ex Wigg. (Liliaceae) is a popular wild vegetable in Southwest P.R. China, the consumption and trade of which has recently been stimulated by local government polices and increasing tourism. We interviewed 68 stakeholders in Northwest Yunnan to document uses, harvest methods and amounts, and locally perceived conservation status of the species. Mainly M. atropurpureum (Franch.) LaFrankie, an endemic of the region, is consumed and collected for trade. Harvest methods and amounts differ significantly between different regions. Major regional markets in Northwest Yunnan are supplied with plants collected around Fugong, Nujiang Prefecture, where the intensive harvest is facilitated by trucks. In Zhongdian, Diqing Prefecture, all harvest is transported by men and sold locally. Only collectors in the latter area perceive a decrease of population sizes in recent years. In that area Maianthemum is decreasing due to several factors, such as relative scarcity of the species, habitat destruction, harvest methods, and increasing demand by tourists. Thus, local harvest strategies, which allow a sustainable use of the populations, need to be developed.
