Bamboo is the dried fruit of the small tiller plant Nandina domestica Thunb. The author isolated and identified from the fruit a variety of alkaloids. Isolation and identification: commercially available bamboo 1.5kg, extracted with methanol, obtained from the non-phenolic basic part of the main known components of oxymethyl nbutane (C_ (20) H_ (21) O_ (4) (Ⅰ) 5.9g, and the mother liquor was separated by silica gel column chromatography. From the part of the CH_2Cl_2 eluted, 12mg of alkali A (Ⅱ) and 12mg of alkali B (Ⅲ)
