| 对腾冲红花油茶7个种群的维生素E、谷甾醇、角鲨烯和总酚含量及其变异进行分析。结果
表明,腾冲红花油茶油含有的维生素E种类为α-Ve,平均含量为(26.71±7.060)mg/100g;甾醇为β-
谷甾醇,平均含量为(287.663±40.430) mg/kg;角鲨烯和总酚平均含量分别为(137.95±72.55)
mg/kg 和(14.36±2.532)g/kg。四者含量在不同单株间存在一定变异,其中角鲨烯变异幅度最大,
变异系数达52.59%,最大与最小单株之间相差17.7倍;维生素E 的变异幅度次之,变异系数为
26.43%,最大与最小单株之间相差3 倍;总酚变异幅度较小,变异系数为17.64%,最大与最小单株
之间相差2.5倍;β-谷甾醇变异幅度最小,最大与最小单株之间相差2倍。不同种群间总酚含量
差异达极显著水平(P<0.01),β-谷甾醇含量差异达显著水平(P<0.05),维生素E 和角鲨烯含量
差异不显著(P>0.05)。维生素E 含量与β-谷甾醇和总酚含量存在极显著正相关,角鲨烯含量与
其余3种活性物质含量之间、谷甾醇含量与总酚含量之间无相关性。腾冲红花油茶含有丰富维生
素E、谷甾醇、角鲨烯和酚类物质,是一种优质的木本食用油。可以利用单株遗传差异选育出活性
物质含量高的特异单株,培育出高价值的优良品种。 |

| The analysis was conducted on the content and variation of vitamin E, sitosterol, squalene, and
total phenolics in seven populations of Camellia reticulata Lindl. The results showed that the form of vitamin
E in Camellia reticulata Lindll was α-Ve, with an average content of (26.71±7.060) mg/100g; β-
sitosterol was the predominant sterol, averaging at (287.663±40.430) mg/kg; squalene and total phenolics
had average contents of (137.95±72.55) mg/kg and (14.36±2.532) g/kg, respectively. There was a certain variation in the content of the four among different individual plants, with squalene showing the
greatest degree of variability, having a coefficient of variation of 52.59% and a maximal disparity of 17.7-
fold between the highest and lowest individual. This was followed by vitamin E, with a variation coefficient
of 26.43% and a threefold difference between the extremes; total phenolics exhibited lesser variability,
with a coefficient of 17.64% and a 2.5-fold difference between the maximum and minimum; β-
sitosterol had the least variability, with a twofold difference between the highest and lowest individual.
Significant differences were observed among different populations in terms of total phenolics content(P<
0.01) and β-sitosterol content(P<0.05), while the differences in vitamin E and squalene content were
not significant(P>0.05). There was a highly significant positive correlation between the content of vitamin
E and both β-sitosterol and total phenolics, whereas no correlation was found between the content of
squalene and the other three active substances, nor between β-sitosterol and total phenolics. Camellia reticulata Lindll was rich in vitamin E, sitosterol, squalene, and polyphenols, making it a premium quality
woody edible oil. Utilizing the genetic differences among individual plants, it is feasible to select specific
individuals with high content of active substances, thereby cultivating high-value superior varieties. |
