Belamcanda chinensis rhizomes, collected from the Hebei province in China, produced two unusual iridal triterpenes named belamcanolide A ( 22 ), and belamcanoxide A ( 23 ).…”

“…Floral fragrance plays a crucial role in attracting pollinators, communicating with them [1], enhancing plant esthetics, and contributing to the secondary metabolism of ornamental plants. Iris, one of the "three root-rooted flowers in the world", is a well-known fragrant flower with significant decorative value [2][3][4]. Iris typhifolia Kitag, a perennial herb in the Iris family, is mainly distributed in Heilongjiang, Jilin, Liaoning, and Inner Mongolia in China.…”

Floral fragrance, as one of the evaluation indicators for ornamental plants, influences people’s perception of these plants. To explore the volatile compounds and their application value in different parts of Iris typhifolia and to investigate the contributions of each part to the floral aroma, an AIRSENSE electronic nose, principal component analysis (PCA), linear discriminant analysis (LDA), and loading analysis (Loading) are employed to study the differences in floral components among the various parts. Samples from the stamen, pistil, flag petal, and pendant petal are qualitatively and quantitatively analyzed using solid-phase microextraction (SPME) and gas chromatography–mass spectrometry (GC-MS) techniques, combined with spectral library retrieval, cluster analysis, and Odor Activity Value (OAV) calculation. The results show that the electronic nose significantly distinguished the aromas from different parts, and there are significant differences in aroma composition. Through cluster analysis and OAV calculation, it is found that the pistil makes the primary contribution to the floral profile of Iris typhifolia, due to the presence of caproaldehyde, 2-methoxy-3-sec-butylpyrazine, and abundant terpenes. This research provides a valuable reference for reconstructing the floral aroma profile, extracting bioactive substances, and exploring aromatherapy with Iris typhifolia.

“…As one of the "world's top three perennial flowers," Iris spp. is a well-known fragrant plant with high decorative value and is frequently used for the extraction of aromatic essential oils and cosmetic ingredients (Krick et al, 1983;Marner & Hanisch, 2001). Baser et al used microdistillation to extract the essential oils of Iris pseudacorus and Iris kerneriana and identified 52 and 54 volatile organic compounds (VOCs), respectively, by gas chromatography-mass spectrometry (GC-MS), with the highest content of alkanes and acids (Bas ¸er et al, 2011).…”

Iris lactea var. chinensis (Fisch.) Koidz has a unique floral fragrance that differs from that of other Iris spp.; however, its characteristic aroma composition remains unknown. This study aimed to identify the floral fragrance components of I. lactea var. chinensis during different flowering stages using headspace solid‐phase microextraction in conjunction with gas chromatography mass spectrometry, electronic nose, and sensory evaluation. During the three flowering phases (bud stage, bloom stage, and decay stage), 70 volatile organic compounds (VOCs), including 13 aldehydes, 13 esters, 11 alcohols, 10 alkanes, 8 ketones, 7 terpenes, 7 benzenoids, and 1 nitrogenous compound, were identified. According to principal component analysis, the primary VOCs were (−)‐pinene, β‐irone, methyl heptenone, phenylethanol, hexanol, and 2‐pinene. A comparison of the differential VOCs across the different flowering stages using orthogonal partial least squares discriminant analysis and hierarchical clustering analysis revealed that 3‐carene appeared only in the bud stage, whereas hexanol, ethyl caprate, ethyl caproate, linalool, (−)‐pinene, and 2‐pinene appeared or were present at significantly increased levels during the bloom stage. The phenylethanol, methyl heptenone, 3‐methylheptane, and β‐irone reached a peak in the decay stage. The odor activity value and sensory evaluation suggested that “spicy” is the most typical odor of I. lactea var. chinensis, mainly due to 2‐methoxy‐3‐sec‐butylpyrazine, which is rare in floral fragrances.
