GC-MS analysis of the metatarsal gland secretion from a female sika deer, Cervus nippon, showed 35 major volatile compounds that included 13 straight-chain carboxylic acids, a single branched-chain carboxylic acid, 9 straight-chain aldehydes, 3 monounsaturated aldehydes, 5 long-chain alcohols, a ketone, and cholesterol. The four most abundant compounds were heptanal, nonanal, octanoic acid, and 6-methyl-2-heptanone. Many of the compounds have previously been found in cervid secretions, but the unsaturated aldehydes, (E)-2-octenal, (E)-2-nonenal, and (E)-2-decenal, have not previously been reported in the glands of any cervid. The compounds in this gland may be pheromones, since metatarsal gland odor has been implicated in chemical communication among conspecifics of other cervids.
对一只雌性梅花鹿（Cervus nippon）跖腺分泌物的气相色谱-质谱联用（GC-MS）分析显示，其中有35种主要挥发性化合物，包括13种直链羧酸、1种支链羧酸、9种直链醛、3种单不饱和醛、5种长链醇、1种酮和胆固醇。含量最高的四种化合物是庚醛、壬醛、辛酸和6-甲基-2-庚酮。许多化合物此前已在鹿科动物分泌物中被发现，但不饱和醛（E）-2-辛烯醛、（E）-2-壬烯醛和（E）-2-癸烯醛此前尚未在任何鹿科动物的腺体中被报道。该腺体中的化合物可能是信息素，因为跖腺气味与其他鹿科动物同种个体之间的化学通讯有关。
