Studi Floristik Famili Euphorbiaceae Berdasarkan Karakter Morfologi Dan Fitokimia Di Universitas Riau
Euphorbiaceae is one of the angiosperms, including diverse flowering plants and a wide distribution. This family is widely used as a medicinal plant, plays a role in industry, medicine, and agriculture and contributes to biodiversity in the plant world. This study aims to identify the diversity of plants from the Euphorbiaceae family based on morphological characters and phytochemical content in the Riau University area. Sampling was done by exploration method. Samples were identified based on morphological characters and phytochemical tests. Kinship analysis of Euphorbiaceae plant species was carried out using the NTSys pc 2.02i program. The data obtained were presented in the form of tables, figures, identification keys, dendrograms and descriptive analysis. The results showed that in the Euphorbiaceae family there were 14 genus, 24 species and 29 plant collections. The genus of the Euphorbiaceae family found are Acalypha, Aleurites, Blumeodendron, Cnidoscolus, Condiaeum, Endospermum, Euphorbia, Excoecaria, Hevea, Homalanthus, Jatropha, Macaranga, Mallotus, and Manihot. All plant species were identified as containing chemical compounds such as alkaloids, flavonoids, saponins, and tannins, while most contained steroids and terpenoids found in several plant species. These results indicate the potential of plants of the Euphorbiaceae family as medicinal plants. The results of kinship analysis of 29 Euphorbiaceae plant collections have coefficient values ranging from 0.16-0.92. The dendrogram results are divided into two large groups, namely group A consisting of plants with herbaceous habitus and group B consisting of large plants with shrub and tree habitus with a coefficient of 0.35. The separation of these groups is based on differences in the morphological characteristics of each species.
