摘　　要：以松树皮为原料,采用微生物破壁法提取原花青素。对固液比、接种量、发酵温度及培养时间4个因素进行单因素试验,在此基础上通过正交试验确定了松树皮中原花青素的最佳提取工艺条件:固液比为5%,接种量7%,发酵温度35℃,培养时间24h。在此条件下,松树皮中原花青素提取率达8.15%。The proanthocyanidins was extracted from the pine bark by microbial wall-broken method.Four conditions for fermentation including ration of liquid to material,inoculation size,fermentation period and fermentation temperature were explored by single factor experiments.Based on orthogonal experiments,optimum extract conditions were obtained：ratio of liquid to material was 5%,inoculation size 7%,the temperature of fermentation was 35℃ and the formation period was 24 h.Under these optimized conditions,the extraction yield of proanthocyanidins reached 8.15%.
