摘要

Angiogenesis is a critical biological process that supports tumor growth and metastasis by enabling sustained oxygen and nutrient delivery. Inhibiting angiogenesis is therefore a mechanistically relevant strategy in cancer research, and natural products—including marine-derived extracts—remain important candidates for screening. This study evaluated the anti-angiogenic potential of Kappaphycus alvarezii (sea moss) crude extract using a chorioallantoic membrane (CAM) assay on fertilized duck eggs. A true experimental design was implemented with four extract concentrations (1, 10, 100, and 200 µg/mL), a negative control (distilled water), and a positive control (70% ethanol). Phytochemical screening reported the presence of sterols, triterpenes, flavonoids, alkaloids, saponins, glycosides, and tannins. Anti-angiogenic outcomes were quantified through ImageJ-derived vascular length, vessel diameter, and vascular density metrics, assessed across three independent trials (n = 18 eggs total; 3 trials × 6 groups). One-way ANOVA results indicated no statistically significant group differences for vascular length (p = 0.153) and vascular diameter (p = 0.367). In contrast, vascular density differed significantly across groups (p = 0.001), with post-hoc tests indicating significant differences between the negative control and the 100 µg/mL and 200 µg/mL conditions. The 200 µg/mL condition was not significantly different from the positive control for vascular density. Overall, the findings provide preliminary CAM-based evidence that K. alvarezii crude extract exhibits anti-angiogenic activity most clearly via vascular density reduction at higher concentrations, warranting further fractionation, safety testing, and validation in additional models.
