Abstract

Butterfly pea flower (Clitoria ternatea) is a herbal plant known for its health benefits due to the presence of various bioactive compounds. This study aimed to identify the phytochemical compounds contained in butterfly pea flowers through an extraction method using ethanol as the solvent. The flower samples were dried and homogenized using a homogenizer until a fine powder was obtained. The powder was then macerated with 96% ethanol for 2 × 24 hours to obtain a concentrated extract. The resulting extract was analyzed through qualitative phytochemical screening to identify the presence of qualitative phytochemical screening to identify the presence of secondary metabolites, including alkaloids, flavonoids, saponins, tannins, phenols, steroids, and terpenoids. The results showed that butterfly pea flower extract positively contained flavonoids, saponins, tannins, phenols, steroids, and terpenoids. The presence of potential as a natural material with biological activity, particularly as a source of antioxidants. This study is expected to provide supporting data for the development and utilization of butterfly pea flower in the health sector and natural-based products.

Abstract

White turmeric (Curcuma zedoaria) is one of the strategic bio-pharmaceutical plants commonly used as a cooking ingredient and as a family medicinal plant. In the Lampung region, turmeric ranks among the top five highest-yielding bio-pharmaceutical crops, making it an abundantly available commodity. This research aims to explore the endophytic bacteria present in turmeric and to investigate the functional abilities of the isolated strains. Endophytic bacteria are microorganisms that inhabit plant tissues and can act as plant growth promoters. In addition, these bacteria can solubilize phosphate, thereby supporting plant growth. Endophytic bacteria also produce the phytohormone IAA, which plays an important role in plant development. This study obtained three endophytic bacterial isolates from the leaves of white turmeric plants, namely KPD1, KPD2, and KPD3. Isolates KPD2 and KPD3 exhibited phosphate-solubilizing activity, as indicated by the formation of clear zones measuring 2.5 ± 0.58 mm and 4.0 ± 0.82 mm, respectively. In addition, all isolates were able to produce indole-3-acetic acid (IAA), with concentrations of 54.98 µg/mL (KPD2), 54.14 µg/mL (KPD3), and 25.05 µg/mL (KPD1). The abilities demonstrated by these endophytic bacterial isolates indicate their potential as plant growth-promoting bacteria (PGPB).
