Abstract: A study was
conducted on the determination of vitamin C content in red dragon fruit
(Hylocereus costaricensis (F.A.C. Weber) Britton & Rose) from three regions
in West Sumatera using UV-Vis spectrophotometry method. Each sample was
measured by a UV spectrophotometer with a wavelength of 264 nm. The results of
this study showed the levels of vitamin C of H. costaricensis S.1 sample from
Sumani, Solok 0,3003 mg / g, S.2 sample from Ketaping, Padang Pariaman 0,3205
mg / g and S.3 sample from Lubuk Minturun, Padang 0.2673 mg / g. Statistical
analysis using one-way ANOVA showed that vitamin C content was significantly
