  The pentacyclic triterpenoids from birch (Betula platyphylla suk) have broad pharmacological activities and can be potentially used for the development of anti-cancer and anti-AIDS drugs. In this study, we explored the effects of spraying 3-year old white birch with different concentration of methyl jasmonate (MeJA) and salicylic acid (SA) on the expression of key genes in triterpenoid biosynthesis pathways and on the accumulation and physiological characteristics of triterpenoids in birch saplings. The results show that, spraying different concentration of MeJA and SA could obviously promote accumulation of total triterpenoids in 3-year old white birch. The triterpenoid content in the stem bark was significantly increased after 1d of treatment with 1 mmol·L-1 MeJA (MJ2) and after 14 d of treatment with 5 mmol·L-1 SA(SA1.. View More»
