    摘要:

    利用气-质联用(GCMS)和液-质联用(HPLC-ESI-MS)技术,在我国原产和主栽的无患子科(Sapindaceae)果树荔枝 Litchi chinensis 和龙眼 Dimocarpus longan中检测到丰富的白坚木皮醇,在‘黑叶’荔枝的叶片、树皮、果皮、果肉和种子中,其白坚木皮醇质量分数分别达到7.7、4.6、10.8、1.6和9.6 g·kg-1,‘储良’龙眼中其白坚木皮醇质量分数分别达到7.6、7.3、5.6、6.3和5.6 g·kg-1,同时比较了不同荔枝品种假种皮白坚木皮醇含量的差异,并探讨了利用荔枝和龙眼栽培和加工废弃物提取市场价值高的白坚木皮醇的可行性.

    Abstract:

    Quebrachitol is one of the naturally occurring bioactive inositol stereoisomers, which can be used to synthesize nontoxic chiral medicine for cancer, Alzheimer's disease, diabetes, etc. In the present study, abundant quebrachitol was identified in Sapindaceae fruit crops, Litchi chinensis and Dimocarpus longan using GCMS and HPLC-ESI-MS. High concentrations of quebrachitol were detected in the leaf, bark, pericarp, aril and seed of the species. In litchi cv. Heiye, their concentrations were 7.7, 4.6, 10.8, 1.6 and 9.6 g·kg-1, respectively. In longan cv. Chuliang, their concentrations were 7.6, 7.3, 5.6, 6.3 and 5.6 g·kg-1, respectively. Quebrachitol concentrations in the aril of twelve litchi cultivars were surveyed. The possible use of the residue from litchi and longan processing for quebrachitol isolation was also discussed.
