Abstract

Rambutan (Nepelium lappaceum) is one of tropical fruit plant that poses high morphological character, both cultivated or wild plants. The exploration of Nephellium in Riau Province had indicated 3 variations of wild Nephellium (Mone, Tunyiang dan Rambutan Hutan). The aim of this study was to examined the phytochemical contents of fruit from three wild Nephellium from Riau Province. Samples used in this study were three fruit parts (pericarp, aril and seed). Phytocemical tests were conducted qualitatively for alkaloid, terpenoid, steroid, flavonoid, saponin and tannin. The result showed that each fruit part had different phytochemical contents. Alkaloid was only found in aril of all wild Nephellium (Mone, Tunyiang dan Rambutan Hutan). Terpenoid and saponin were found in all fruit parts, while saponin was absent in all fruit parts from three wild Nephellium.  ditemukan pada semua bagian buah dari ketiga buah rambutan liar. The result of this study provides additional information of phytochemical content of wild N. lappaceum.

Abstract

Minangkabau ethnic has rich natural and cultural resources. The Minangkabau ethnic community in Lima Puluh Kota Regency, West Sumatra, possesses rich traditional knowledge in utilizing local plant species as ingredients in their culinary heritage. This study aimed to document the ethnobotanical use of food plants and examine their phytochemical properties to assess their potential as functional foods. Ethnobotanical data were collected using open-ended interviews and field observations involving key informants from various Nagari (villages) selected using purposive sampling methods. Phytochemical tests were conducted to identify alkaloids, saponins, steroids, tannins, and triterpenoids in the plants used. The study identified 43 plant species belonging to 29 families used as the main ingredients in 20 types of traditional culinary with plant species are dominated by Fabaceae. Leaves were the most frequently used plant parts, followed by fruits, stems, flowers, and tubers. These ingredients were sourced from wild and cultivated plants growing in yards, gardens, and fields. Phytochemical screening of  plants revealed the presence of secondary metabolites including alkaloids (13 species), flavonoids (26), saponins (21), tannins (21), triterpenoids (16), and steroids (8). The findings of our study indicate that traditional Minangkabau food plants are not only culturally significant but also possess medicinal potential, warranting further scientific exploration and conservation of local knowledge.
