The fruit is a wild fruit that may be eaten and used medicinally. Its seeds are rich in nutrients but are typically thrown away without processing.The physicochemical characterization, volatiles, fatty acids, lipids and concomitants of cold-processed seed oils from four kinds of were evaluated. The average kernel yield and oil yield of seeds were 68.21 % and 30.44 %, respectively. The seed oil contains a moderate level of total phenolics (368.99-503.99 mgGAE/100 g), total flavonoids (95.01-126.18 mg RE/100 g), and β-sitosterol (1498.8-1712.7 mg/kg) with higher iodine value, lower acid value, saponification value and shorter induction time. GC analysis reveals appreciable amounts of linoleic acid (64.91-68.05 %) and squalene in seed oil. GC-MS analysis showed that the major volatile compounds were γ-muurolene (27.25-31.7 %), β-himachalene (19.51-20.37 %) and β-curcumene (15.78-16.78 %). Moreover, 16 terpenoids, 14 phenolics were identified by UPLC-QTOF-MS/MS. These results suggest that seed seems an promising alternative oilseed with biological ingredients for food, cosmetics and pharmaceutical industries.
这种果实是一种可食用且具有药用价值的野生果实。其种子富含营养，但通常未经加工就被丢弃。对四种[果实名称未给出]冷榨种子油的理化特性、挥发性成分、脂肪酸、脂质及伴随物进行了评估。[果实名称未给出]种子的平均仁产量和出油率分别为68.21%和30.44%。种子油含有适量的总酚（368.99 - 503.99 mg GAE/100 g）、总黄酮（95.01 - 126.18 mg RE/100 g）和β-谷甾醇（1498.8 - 1712.7 mg/kg），碘值较高，酸值、皂化值较低，诱导时间较短。气相色谱分析表明种子油中含有大量的亚油酸（64.91 - 68.05%）和角鲨烯。气相色谱-质谱联用分析表明主要挥发性化合物为γ-穆罗烯（27.25 - 31.7%）、β-喜玛拉雅烯（19.51 - 20.37%）和β-姜黄烯（15.78 - 16.78%）。此外，通过超高效液相色谱-四极杆飞行时间串联质谱法鉴定出16种萜类化合物和14种酚类化合物。这些结果表明，[果实名称未给出]种子似乎是一种有前景的替代油料种子，可为食品、化妆品和制药行业提供生物成分。
