Rose (Rosa sp.) is one of the most important ornamentals which is commercialize for its aesthetic values, essential oils, cosmetic, perfume, pharmaceuticals and food industries in the world. It has wide range of variations that is mostly distinguished by petal color differences which is interlinked with the phytochemicals, secondary metabolites and antinutrient properties. Here, we explored the color, bioactive compounds and antinutritional profiling and their association to sort out the most promising rose genotypes. For this purpose, we employed both quantitative and qualitative evaluation by colorimetric, spectrophotometric and visual analyses following standard protocols. The experiment was laid out in randomized complete block design (RCBD) with three replications where ten rose genotypes labelled R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 were used as plant materials. Results revealed in quantitative assessment, the maximum value of lightness, and the luminosity indicating a brightening of rose petals close to a yellow color from rose accessions R4, and R10, respectively which is further confirmed with the visually observed color of the respective rose petals. Proximate composition analyses showed that the highest amount of carotenoid and β-carotene was found in R10 rose genotype, anthocyanin and betacyanin in R7. Among the bioactive compounds, maximum tocopherol, phenolic and flavonoid content was recorded in R8, R6 and R3 while R1 showed the highest free radical scavenging potentiality with the lowest IC (82.60 µg/mL FW) compared to the others. Meanwhile, the enormous variation was observed among the studied rose genotypes regarding the antinutrient contents of tannin, alkaloid, saponin and phytate whereas some other antinutrient like steroids, coumarines, quinones, anthraquinone and phlobatanin were also figured out with their presence or absence following qualitative visualization strategies. Furthermore, according to the Principal Component Analysis (PCA), correlation matrix and cluster analysis, the ten rose genotypes were grouped into three clusters where, cluster-I composed of R3, R4, R5, R8, cluster-II: R9, R10 and cluster-III: R1, R2, R6, R7 where the rose genotypes under cluster III and cluster II were mostly contributed in the total variations by the studied variables. Therefore, the rose genotypes R9, R10 and R1, R2, R6, R7 might be potential valuable resources of bioactive compounds for utilization in cosmetics, food coloration, and drugs synthesis which have considerable health impact.
玫瑰（Rosa sp.）是世界上最重要的观赏花卉之一，因其美学价值、精油、化妆品、香水、制药和食品工业而商业化。它有广泛的变化，主要区别在于花瓣颜色的差异，这与植物化学物质、次生代谢物和抗营养特性有关。在这里，我们探索了颜色、生物活性化合物和抗营养特性及其与分类的关系，以筛选出最有前途的玫瑰基因型。为此，我们采用了比色法、分光光度法和视觉分析等定量和定性评估方法，并按照标准协议进行了实验。实验采用完全随机区组设计（RCBD），设三个重复，使用 10 个玫瑰基因型 R1、R2、R3、R4、R5、R6、R7、R8、R9 和 R10 作为植物材料。在定量评估中，结果表明，R4 和 R10 玫瑰花瓣的亮度和明度值最大，表明花瓣接近黄色，这与各自玫瑰花瓣的视觉观察颜色进一步证实。组成分析表明，R10 玫瑰基因型的类胡萝卜素和β-胡萝卜素含量最高，R7 玫瑰基因型的花色苷和甜菜碱含量最高。在生物活性化合物中，R8、R6 和 R3 的生育酚、酚类和类黄酮含量最高，而 R1 的自由基清除能力最强，IC（82.60µg/mL FW）最低，与其他玫瑰相比。同时，在所研究的玫瑰基因型中，单宁、生物碱、皂苷和植酸的抗营养含量存在巨大差异，而其他一些抗营养物质，如甾体、香豆素、醌、蒽醌和菲烷，也通过定性可视化策略确定了其存在或不存在。此外，根据主成分分析（PCA）、相关矩阵和聚类分析，将这 10 个玫瑰基因型分为三个聚类，其中，聚类 I 由 R3、R4、R5、R8 组成，聚类 II：R9、R10，聚类 III：R1、R2、R6、R7，其中聚类 III 和聚类 II 的玫瑰基因型主要由研究变量贡献了总变异。因此，R9、R10 和 R1、R2、R6、R7 等玫瑰基因型可能是生物活性化合物的潜在有价值资源，可用于化妆品、食品着色和药物合成，具有相当大的健康影响。
