A Qualitative test of Primary and Secondary Metabolites of Bintaro Plant as a Rat (Rattus argentiventer) Pest Repellent

Abstract

Bintaro is a mangrove plant that grows on the coast and is often used as a shade tree in megacities. The toxic content of the Bintaro plant is found in all parts of the plant. The toxic content of cardiac glycoside compounds contained in the Bintaro plant can be used as a rat repellent. Rat pests are important pests in crops, especially in rice plants which are difficult to control in mechanically and chemically, thus rice production always decreases. Therefore, it is necessary to search for effective, efficient, and environmentalfriendly control technology, namely by using fruit extracts. The plant-based rodenticides made from Bintaro fruit extracts are effective for overcoming rat pests. The purpose of the study was to determine the qualitative levels of primary and secondary metabolites from Bintaro plants which act as antifeedants for rat pests (Ratus argiventer). The method used in this research was qualitative testing using phenol method to test the content of primary and secondary metabolites in the leaves and stems of Bintaro plants. From the results of the research conducted, it was found that the qualitative levels of primary metabolites from Bintaro leaves and stems contained protein content. Fat and carbohydrate content of secondary metabolites found in the stems and leaves of the Bintaro plants were Alkaloids, Saponins, Flavonoids and Polyphenols in Bintaro leaves and on its stems contained Flavonoids, Saponins, Tannins and alkaloids.

Skrining Fitokimia Hasil Ekstraksi Bertingkat Daun Jengkol (Archidendron jiringa) dan Aplikasinya Sebagai Zat Antijamur

“…Ada dua jenis metabolisme pada tumbuhan, yaitu metabolisme primer dan metabolisme sekunder. Metabolisme primer menghasilkan senyawa yang digunakan dalam proses biosintesis, sedangkan metabolisme sekunder menghasilkan senyawa aktif yang dapat digunakan sebagai zat antimikroba, antioksidan, antijamur, antitumor, dan banyak fungsi lainnya (Susanti et al, 2020). Beberapa jenis metabolit sekunder yang ada pada tumbuhan adalah alkaloid, fenolat, glikosida, terpenoid, dan steroid (Teoh, 2015).…”

“…Flavonoid menyerang beberapa organ saraf (Muta'ali dan Purwani, 2015). Alkaloid bersifat toksik dan menghambat aktivitas makan (Susanti et al, 2020). Senyawa triterpenoid sebagai senyawa antimakan (Budianto dan Tukiran, 2012).…”
