Perbedaan Struktur Morfologi, Anatomi, dan Fisiologi serta Kandungan Fitokimia Daun Aur-Aur (Commelina diffusa) pada Intensitas Cahaya Berbeda di Embung Leuwi Padjadjaran

Commelina diffusa (family Commelinaceae) contains various secondary metabolites with potential antimicrobial and antioxidant properties. The production of these compounds is influenced by environmental factors, particulary light intensity, which also play a role in determining the plant’s morphological and anatomical characteristics. This study aims to analyze differences in leaf morphology, stomatal anatomical structure, chlorophyll content, and phytochemical compounds in C. diffusa leaves growing in two locaition with different light conditions at Embung Leuwi Padjadjaran, Sumedang. A descriptive method was used to examine leaf morphology, stomatal anatomy, chlorophyll content, and phytochemical compounds of C. diffusa in shaded and unshaded location. The results showed that leaf morphology was relatively similar in both location, but the leaf surface area was larger in unshaded conditions (8,33 cm²). The stomata were hexacytic type with higher stomatal density in the shaded condition (591,082 cell/mm²), as well as a higher chlorophyll content (37,73 CCI). Phytochemical analysis confirmed the presence of alkaloids, flavonoids, saponins, tannins, and quionones, were relatively higher in unshaded conditions.
