Identification
Morphology
Halleria lucida is a versatile plant that primarily takes the form of a self-supporting tree. Depending on its specific environment, its growth can vary significantly in scale. While some specimens may remain quite small at a height of only 0.3 m, others can develop into much more substantial structures. Many healthy trees reach a substantial stature of at least 10 m. Ultimately, these trees can achieve a maximum height of up to 12 m.

Biological Activities
Halleria lucida has demonstrated significant medicinal potential through its documented antibacterial and antioxidant properties. Research indicates that the methanol extracts of the plant's leaves and stems possess notable antioxidant activities, with the leaves showing higher efficacy in tests like DPPH and ABTS. While the overall antibacterial response against Gram-positive and Gram-negative bacteria was somewhat limited, specific successes were observed in the stem extracts. Notably, the stem extract exhibited targeted antibacterial activity against Bacillus cereus and Staphylococcus epidermidis. Ultimately, these findings provide valuable validation for the therapeutic uses of both the leaves and stems of this species.
Compounds
Halleria lucida possesses significant medicinal potential, particularly through the presence of bioactive compounds in its leaves and stems. Chemical evaluations reveal that this plant contains essential flavonoids, which contribute to its overall biological profile. Additionally, the presence of proanthocyanidins plays a key role in the plant's antioxidant properties. Research indicates that the concentration of these substances varies between the leaves and the stems, influencing their specific medicinal efficacy. Ultimately, these phytochemical components help validate the therapeutic value of Halleria lucida in various applications.
Conditions
Halleria lucida demonstrates antibacterial properties through the use of its stem methanol extracts. Specifically, these extracts are effective in treating the bacteria Bacillus cereus. The plant also shows activity against Staphylococcus epidermidis when the stem extract is applied. Both of these bacterial targets were inhibited at a minimum inhibitory concentration of 1.0 mg/ml. Consequently, the stem of Halleria lucida serves as a medicinal agent against these specific organisms.
Preparations
Parts used
Halleria lucida serves as a significant subject of study due to the diverse medicinal properties found within its various components. Research indicates that both the leaves and the stems of this plant contain valuable methanol extracts for pharmacological evaluation. While the leaf extracts demonstrate superior antioxidant activities, the stem extracts possess higher concentrations of total phenols and flavonoids. Additionally, the stem has shown specific antibacterial effectiveness against organisms such as Bacillus cereus and Staphylococcus epidermidis. Ultimately, these findings validate the medicinal potential inherent in both the leaves and stems of the species.
