Six experimental stages were designed in our procedure, those are:(1) metabolite recovery and tested sample preparation: the metabolites were recovered by Amberlite XAD-2 absorption, followed by MeOH elution and solvent concentration;(2) antioxidant detection and strain selection: samples were quantitatively analyzed by the inhibition effects on formation of lipid peroxides and TBARS to screen the strains able to produce antioxidants. According to the established screening methods, we chose out a strain of actinomycetes, designed as AMBL-029C;(3) antioxidant purification: the fermentation broth was recovered by a series of separation techniques including centrifugation, Amberlite XAD-2 absorption, followed by MeOH elution and a successive TLC purification. The resulting primary purified compound [temperately designed as AMBL-029C-TS] was further analyzed by HPLC to monitor its purity;(4) physical-chemical characteristics: judging from the acid-base fractionation experiments, and the pH and temperature stability tests, the compound was deduced to be a acidic compound with the properties of low polarity and highly pH and temperature stable;(5) mechanism of the antioxidant: in comparison with some other known antioxidants, TS was subjected to investigate its antioxidant mechanism, together with BHT,-tocopherol, as well as two streptomyces metabolites, homogentisic acid and -phenylpyruvic acid, which were previously isolated as the natural antioxidants in our laboratory.

dioecious：雌雄异株

与上述园艺植物不同,杨梅、银杏、猕猴桃、阿月浑子、石刁柏等为雌雄异株(dioecious)植物. 由于同种植物雌株与雄株在性状及生产性能上有差异,应区别使用. 如银杏用作行道树时,宜选雄株,以防种实污染行人衣物. 而在大型绿地中结合生产可多选雌株.

Platanus acerifolia：悬铃木

如银杏、合欢、悬铃木(platanus acerifolia)、毛白杨(populus tomentosa)、旱柳(salix matsudana)等. 选择时毛白杨、银杏选雄株,悬铃木选择新育品种少球果悬铃木.
