Phytochemical and agronomic evaluation of selected niyog-niyogan (Combretum indicum (L) DeFilipps) accessions of the Philippine biorepository network
(Don Mariano Marcos Memorial State University- North La Union Campus, 2024-05) Bartolome, Michael Cedric B.
C. indicum is an important but understudied medicinal plant in the Philippines that is often misidentified in the literature and has limited utilization due to the side effects of its seeds. This study evaluated the two preselected C. indicum accessions of the PBN regarding the phytochemical and agro-morphological traits of the leaves as a potential alternative to the seeds as a vermifuge to select a taxonomically verified reference germplasm. Qualitative characterization and quantitative evaluation were adopted, and t- test was used to check differences between the two accessions, with significance evaluated at a 95% confidence level. Flavonoids, saponins, and tannins were detected, and similar levels of antioxidant activity were evaluated in both accessions. Accession 2018-221 was selected as the suitable candidate based on its significantly lower ash (8.90(0.09)%) and crude fiber content (15.02(0.11)%) and its larger (average leaf area – 29.29(11.13)cm2) and heavier leaves, (average fresh weight – 0.44(0.16)g, oven-dried weight – 0.14(0.06)g).
