From the leaves of Neolitsea sericea (BLUME) KOIDZ., 3 kinds of phenolic base (I to III), 3 kinds of non-phenolic base (IV to VI), 3 kinds of water-soluble base (VII to IX) as styphnates, were isolated. Of these, boldine (I) and roemerine (IV) are structurally known bases. (II) and (VI) were thought to be new bases and were respectively named laurolitsine and litsericine. (III) and (V) were contained in the plant in trace amounts and were respectively designated as base-III and base-V. Molecular formulae presumed from their analytical values are as follows: Laurolitsine (II), C18H19O4N=C16H10(OH)2(OCH3)2(NH). Base-III, C19H19O4N=C16H10(O2CH2)(OH)(OCH3)(NCH3). Base-V (isolated as its hydrochloride), C19H17O4N⋅HCl. Litsericine (VI), C17H21O3N=C16H18N(O2CH2)(OH). (VII)-styphnate, C6H14(16)ON⋅C6H2O8N3. (VIII)-styphnate, C9H18ON⋅C6H2O8N3. (IX)-styphnate (choline styphnate), C5H14ON⋅C6H2O8N3.
