6-O-beta-D-Xylopyranosyl-beta-D-glucopyranosides (beta-primeverosides) of (Z)-3-hexenol and trans-linalool 3,7-oxide were newly isolated from fresh leaves of a tea cultivar (Camellia sinensis var. sinensis cv. Yabukita). In addition, the already identified beta-primeverosides of benzyl alcohol, methyl salicylate, and trans-linalool 3,6-oxide from an oolong tea cultivar were isolated from the Yabukita cultivar. It was confirmed that all aglycones of the linalool oxide glycosides isolated here were of the optically active S-form by chiral GC after enzymatic hydrolysis with glycosidase.
从茶树品种（Camellia sinensis var. sinensis cv. Yabukita）的新鲜叶片中首次分离出了(Z)-3-己烯醇和反式芳樟醇3,7-氧化物的6-O-β-D-吡喃木糖基-β-D-吡喃葡萄糖苷（β-樱草糖苷）。此外，从Yabukita品种中还分离出了已在乌龙茶品种中鉴定出的苯甲醇、水杨酸甲酯和反式芳樟醇3,6-氧化物的β-樱草糖苷。在用糖苷酶进行酶促水解后，通过手性气相色谱法证实，这里分离出的芳樟醇氧化物糖苷的所有苷元均为旋光活性的S型。
