A novel chromone analogue, phyllomakin A (1), and a new flavonolignan, (-)-quiquelignan C (2), along with 18 phenolic and 2 triterpenoids, were isolated from the leaves of Phyllostachys makinoi Hayata. The structures of 1–22 were elucidated by an application of various spectroscopic analyses (1D & 2D NMR and MS) and compared with reported data. A biological evaluation showed that compound 3 had very potent anti-NO production activity (IC₅₀ = 4.80 µM), while compounds 2, 6, 11, and 15 showed moderate inhibitory effects (IC₅₀ = 10.19, 13.26, 13.56, and 10.96 µM, respectively) without affecting cell viability at 20 μM.
