The presence of S.jamaicensis in Fields Grow With Other Plants : A Part from the Book Chapter : Determination of Plants Diversity and Similarity in Selected three Communities of Stachytarpheta jamaicensis (L.) Vahl

The presence of S.jamaicensis in fields grow with other plants either native or aliens plants in diverse composition, structure and dominance. These are influenced by environmental factors such as soil, light, human activity and land use systems around the plant. Systems, types, and land use intensity also influence the diversity and composition of plant species in a habitat or region where the plant growing. Solikin reported that the composition and dominance of plant species in the two sites growing areas of S. jamaicensis between in Jeru Village of Malang and Gajahrejo Village Pasuruan which had different environmental conditions, such as the type of land management and climate were different. Whereas the plants’ composition and dominance in the growing area of S. Jamaicensis between Pemping Island and Kepala Jeri Island Batam had similar composition. It is interesting to study whether the composition, dominance and diversity of plant species in three growing sites growing area of this plant in three islands is different or similar.

S. Jamaicensis is distributed and widespread in Central America, the Caribbean, East and Southern Asia, the Pacific, and Africa. Witt and Luke reported that this plant is invasive in Kenya and Tanzania. Although it has potency as an invasive plant and weed on abandoned agricultural land, controlling growth and eradication of this plant by farmers cause S. jamaicensis is rarely found to be invasive and dominant in crop cultivation such as in maize, ground nut, and cassava. Invasive plant species are native or introduced plant species that have become established, dispersed, and generated negative impacts on local ecosystems and the biodiversity of local species. They grow and spread fast so that they were to be dominant and effect on reducing local biodiversity, competing with native organisms for limited resources, ecosystem services, environmental quality, altering habitats, and human health.

Recent Global Research Developments in Antioxidant and α-Glucosidase Inhibition in S. jamaicensis

Antioxidant Activity: The methanol extract of S. jamaicensis leaves demonstrated significant antioxidant activity. This was evaluated using the DPPH (2,2-Diphenyl-1-picrylhydrazyl) and ABTS (2,2’-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid)) methods [1,2].

α-Glucosidase Inhibition: The same methanol extract also displayed α-glucosidase inhibitory activity. Researchers successfully isolated a compound called 6β-hydroxyipolamiide from the leaves, which showed α-glucosidase inhibitory activity with an IC50 of 539.17 μg/mL [1].
