Comparison of Aqueous Extracts from 11 LauraceaeBranches on Liquid Culture of Taiwanofungus camphorates

Our research analyzed the effect of aqueous extract of 11 species of Lauraceae plants on Taiwanofungus camphorates liquid culture through itsmycelium biomass and total triterpenoid, total polysaccharide content . The results show that the11 species of Lauraceae plants have different degrees of stimulatory effects on the mycelial growth of T. camphorates. Among them, the aqueous extracts of N. aurata, C. bodinieri, C. pedunculatum and C. austrosinense have relatively obvious stimulatory effects. The effects of aqueous extracts from 11 species of Lauraceae plants on total triterpene content of mycelium of T. camphorates are quite different, among them, N. aurata, C. kotoense and C. bodinieri have obvious stimulatory effects, the total triterpene contentof mycelium of these aqueous water extracts are 13 times, 10 times and 10 times of the control group (the T. camphorates mycelium from base liquid medium) respectively, and the content increase by 85% , 78.5% and 78.5%.The effect of aqueous extractsfrom C. pedunculatum is slightly greater than that of the pre-optimized liquid medium, while the aqueousextracts from other 8 Lauraceae plants have smaller stimulatory effect in different degrees. The effects of aqueous extracts from 11 species of Lauraceae plants on the total polysaccharide content of T. camphorates mycelia are not as good as those of the pre-optimized liquid medium. The effects ofaqueous extracts from N. aurata and C. bodinieri on the total polysaccharide content are relatively closer to the effect of pre-optimized medium. However ,the aqueous extracts from C. camphora and C. chekiangense show a certain inhibitions when compared with the control group. Through the analysis of the biomass, total triterpenes and polysaccharides of the mycelium of T. camphorates, the results show that the addition of aqueous extract from N. auratahave the most obvious stimulatoryeffect on the liquid culture of T. camphorates, followed by C. bodinieri. Comprehensive analysis of plants karyotype, elevation and natural distribution of the 11 species of Lauraceae, revealsthat N. aurata, which havethe most obvious stimulatory effect , present the same karyotype , high altitude and natural distribution in Taiwan as that of C.kanehirae.. At the same time, it has been proved that C. camphora and C. parthenoxylon have less promoting effect cause its karyotype are different from C. kanehirae, and the promoting effect is in inverse proportion to the altitude, in direct proportion to the natural distribution and relatedness of Taiwan. It is suggested that the three factors would affect the composition of Lauraceae plants,and further speculated that these components may promote the mycelium growth of Lauraceae plants.
