- Observation Leaf powder of T. macrophylla showed raphide crystals, uniseriate trichomes and parasitic stomata.
- Observation Twig powder of T. macrophylla showed raphide crystals.
- Observation Primary phenolic compounds in the active extracts of T. macrophylla were identified as 6-hydroxy-2-(2-phenylethyl) chromone, d-catechin and isorhamnetin.
- Observation Epicatechin gallate was identified as a primary phenolic compound in the active extracts of T. macrophylla.
- Observation The highest total phenolic and flavonoid contents (TPC and TFC) of T. macrophylla were found in the ethyl acetate extract.
