“…As an edible plant, the use of S. zeylanica for human consumption was rst recorded in 1977 by Holm et al in Thailand and Indonesia, where it was said to have been steamed and eaten with rice. In a later study during the 21st century, consumption of the plant was also recorded in Assam, northeast India, where it was fried or boiled (Narzary and Basumatary, 2019). Apart from these reports, however, there are few known instances or cases surrounding the usage of S. zeylanica as a food resource.…”

Background Diversifying food sources by including edible wild plants or weeds as food resources can help to combat the issues of simplified diets and food security in the modern world. The present study investigated the case of Sphenoclea zeylanica Gaertn. (gooseweed or wedgewort), an edible wild plant with traces of historical consumption in Indonesia. Because previous studies have failed to clarify its significance for consumption by society, the present study aimed to clarify the significance of S. zeylanica as a food resource in the 21st century.Methods Data were collected in Bali Province (Denpasar City and Timpag Village, Tabanan Regency) through interviews with a farmer, direct field visits to wet markets and supermarkets, and an online questionnaire. Supply distribution was analyzed using geographical information system mapping to visualize point data density, while statistical significance of consumption data was analyzed using the R software.Results The results showed that S. zeylanica was cultivated as a vegetable crop by local farmers in Timpag Village from 2014. Fresh S. zeylanica could be found mainly sold in wet markets within Denpasar City, while prepared or cooked versions of the plant were noted to be sold in several food and beverage establishments. The selling price of S. zeylanica was also found to be high among other similar vegetables. A majority of the study’s survey respondents have consumed S. zeylanica at least once in the past, with most of them tended to be older and were more often female. However, it was identified that factors such as low production, unequal distribution, and high market pricing were probable causes in limiting its use and consumption. Conclusions It was concluded that S. zeylanica has limited significance in 21st century urban Bali, Indonesia, despite high awareness of the plant as a food resource. However, commercialization and preservation of cultural plant knowledge surrounding S. zeylanica were thought to be potentially important actions for maintaining its use as a future food resource. Consequently, further research is necessary on potential marketing methods and strategies to generate greater interest or demand towards S. zeylanica as a vegetable crop.

Antioxidant Activity, Phenolic Composition, and Hormone Content of Wild Edible Vegetables

et al. 2022

Wild edible plants have been used since antiquity as folk medicine and as preservatives in foods. This study aimed to determine the antioxidant activities, phenolic compounds, and hormone contents of 12 species of edible wild plants belonging to 9 families, which are consumed as vegetables by the local people at Ergan Mountain in Erzincan in Turkey. Polygonum cognatum and Malva neglecta were determined to have more antioxidant enzyme activity, more phenolic compounds, and higher hormone content than the other species. The highest catalase (CAT), peroxidase (POD), glutathione reductase (GR), glutathione-s-transferase (GST) values for P. cognatum were determined as 45.12, 94.83, 36.76, and 1218.35 EU g−1, respectively. The highest superoxide dismutase (SOD) and ascorbate peroxidase (AxPOD) content for M. neglecta were determined as 97.53 EU g−1 and 81.93 EU g−1, respectively. P. cognatum is the species in which the highest levels of the hormones indolacetic acid (IAA), gibberellic acid (GA), salicylic acid (SA), cytokinin, zeatin and jasmonic acid were detected. The highest levels of caftaric acid (CA), catechin (CAE), ferulic acid (FA), malvidin-3-o-glucoside (MG), myricetin (MYR), rutin (RT), trans-coumaric acid (TPCA), tyrosol (TY), and vanilic acid (VA) compounds were found in M. neglecta. It was determined that Falcaria vulgaris species had the highest levels of ferulic acid (FA) and quercetin (QUE) phenolics. The results show that edible wild vegetables consumed and studied by the people of the region are an important source of natural antioxidants. The possibilities of using these wild plants as functional foods should be investigated.
