By comparing with known compound A2'P 5'A,it was shown that two ribose rings of a and b adopt predominantly S conformation at 18℃, but with elevation of temperature, the N conformation of some ribose ring increaed: the torsional angles e' and β of the phosphate backbone were estimated to have a change of +2° and ±12°respectively; two ribose rings of both A2'P(CH3)5'A and were partially overlapped and the degree of overlapping of was smaller than that of the : with increasing of temperature, the adenine moiety of A2'P(CH3)5'A showed a stronger tendency to unstack than A2'P(CH3)5'A .

它们与A2′P5′A相比发现：(1)在18℃时两个核糖环是S型构象占主要成分，但随温度升高有的核糖环趋向于转化成N型构象；(2)磷酸骨架的扭角ε′和β分别改变±2°及±12°；(3)A2′P(CH_3)5′A和的两个核糖环均属部分重叠，并且前者的重叠程度小于后者；(4)随着温度升高，A2′P(CH_3)5′A比A2′P(CH_3)5′A有着更强的去堆积效应。

Result The main components of aqueous infusion of pepper leaf were vanillic acid (75.7 μg/g) and umbelliferon (29.8 μg/g).
