Characterization of Key Odorants in Hoary Mountain Mint, Pycnanthemum incanum.
    Journal of agricultural and food chemistry, 2019, Mar-06, Volume: 67, Issue:9

    Pycnanthemum incanum, a species of wild mountain mint endemic to North America, has a pungent mint-like odor that has not been fully characterized. Due in part to its high terpene content, P. incanum has broad potential for health-promoting, cosmetic, culinary, and food flavoring applications. Therefore, odorants of P. incanum were identified by coupling solvent assisted flavor evaporation (SAFE) and aroma extract dilution analysis (AEDA), which afforded 24 odorants including 14 odorants with flavor dilution (FD) factors ≥4. Selected odorants, including those with FD factors ≥16, were quantitated by stable isotope dilution assays (SIDAs), and odor activity values (OAVs) were determined. The odorants with the highest OAVs included β-ionone (floral, violet; OAV 300), myrcene (terpeny, OAV 120), linalool (floral, citrus; OAV 79), and pulegone (mint, medicinal; OAV 58). An odor-simulation model based on the quantitation closely matched the sensory attributes of the original P. incanum plant material. In addition, enantiomeric proportions of chiral odorants in P. incanum were determined by chiral chromatography.

Analysis of aroma-active compounds in three sweet osmanthus (Osmanthus fragrans) cultivars by GC-olfactometry and GC-MS.
    Journal of Zhejiang University. Science. B, 2014, Volume: 15, Issue:7

    Aroma is the core factor in aromatherapy. Sensory evaluation of aromas differed among three sweet osmanthus (Osmanthus fragrans) cultivar groups. The purpose of this study was to investigate the aroma-active compounds responsible for these differences.. Gas chromatography-olfactometry (GC-O) and GC-mass spectrometry (GC-MS) were used to analyze the aroma-active compounds and volatiles of creamy-white ('Houban Yingui', HBYG), yellow ('Liuye Jingui', LYJG), and orange ('Gecheng Dangui', GCDG) cultivars.. Seventeen aroma-active compounds were detected among 54 volatiles. trans-β-Ocimene, trans-β-ionone, and linalool, which were major volatiles, were identified as aroma-active, while cis-3-hexenyl butanoate, γ-terpinene, and hexyl butanoate were also aroma-active compounds, although their contents were low. Analysis of the odors was based on the sum of the modified frequency (MF) values of aroma-active compounds in different odor groups. HBYG contained more herb odors, contributed by cis-β-ocimene and trans-β-ocimene, while LYJG had more woody/violet/fruity odors released by trans-β-ionone, α-ionone, and hexyl butanoate. In GCDG, the more floral odors were the result of cis-linalool oxide, trans-linalool oxide, and linalool.. Aroma-active compounds were not necessarily only the major volatiles: some volatiles with low content also contributed to aroma. The aroma differences among the three cultivars resulted from variation in the content of different odor groups and in the intensities of aroma-active compounds.

Volatiles of Lysimachia paridiformis Var. Stenophylla, Lysimachia fortumei and Lysimachia chikungensis by HS-SPME-GC-MS.
    African journal of traditional, complementary, and alternative medicines : AJTCAM, 2014, Volume: 11, Issue:3

    Lysimachia paridiformis Var. Stenophylla mainly contain flavonoid constituents. Flavonoids and benzoquinones are the main compounds in L. fortumei Maxim. The objective of this paper was to study the volatile compounds of leaves in L. paridiformis Var. Stenophylla, L. fortumei and L. chikungensis for the first time.. Volatiles were extracted by the manual solid phase micro-extraction (SPME). The volatile constituents were analyzed by an Agilent 6890 N gas chromatograph equipped and coupled with a 5975B mass selective detector spectrometer.. Twenty-nine compounds were identified in the leaves of L. paridiformis var. Stenophylla, accounting for 89.17% of the total volatile fraction. The main constituents were ethanol (13.58%), and β-ionone (8.05%). linalool and β-ionone were the main aroma constituents in L. paridiformis var. Stenophylla. Twenty-one compounds were identified in the leaves of L. fortumei, accounting for 94.72% of the total volatile fraction. The main constituents were tricosane (14.72%), docosane (11.02%), tetracosane (10.77%) and pentacosane (9.81%). Thirty-two compounds were identified in the leaves of L. chikungensis, accounting for 88.58% of the total volatile fraction. Typical compounds detected in L. chikungensis were cis-3-hexenyl pentanoate (13.33%), followed by ethanol (12.13%), ethyl palmitate (7.78%), and heneicosane (5.38%).. The results showed that the main composition types were similar in the three plants, but the content was different, which indicated that the similar composition types provided the same medical effect for three plants.
