Volatile Constituents of Chinese Chive(Allium tuberosumRottl. ex Sprengel) and Rakkyo(Allium chinenseG. Don)

Abstract

Volatile components were isolated from Chinese chive and rakkyo by simultaneous steam distillation-solvent extraction and analyzed by GC and GC-MS. Sulfur compounds account for 88 and 94% of the total volatiles in the isolated extract of Chinese chive and rakkyo, respectively. In addition to the sulfur compounds commonly reported in the genus Allium, 27 novel volatile sulfur-containing components were found in the isolated extracts of both species. Among them were a sulfide, disulfides, trisulfides, and tetrasulfides with ethyl, butyl, and pentyl groups.

Isolation ofS-n-Butylcysteine Sulfoxide and Sixn-Butyl-Containing Thiosulfinates fromAllium siculum

“…The 1 H and 13 C NMR spectroscopic data together with a very strong IR absorption band at 1020 cm -1 (SdO) and MALDI-HRMS [MH + ] of 194.0846 (calcd for C 7 H 16 NO 3 S 194.0845) confirmed the structure of the amino acid as S-nbutylcysteine sulfoxide. CD and 1 H NMR spectroscopy were employed to determine the absolute configuration at the two chiral centers of the compound (at the sulfur and the R-carbon).…”

“…Indeed, it has been shown in numerous subsequent studies utilizing more sensitive GC and HPLC techniques that BCSO does not occur in garlic at levels > 0.01 mg g -1 fresh weight. 4,[7][8][9][10][11][12][13][14] It may however be present in some other alliaceous species in trace quantities, as indicated by the finding of several n-butyl-containing sulfides in onion (Allium cepa L.) 15 and Chinese chive (Allium tuberosum L.) 16 volatiles.…”

Spirostanol saponins from Chinese onion (Allium chinense) exert pronounced anti-inflammatory and anti-proliferative activities

“…Previous phytochemical investigation has led to the identification of sulphur-containing compounds (Pino, Fuentes, & Correa, 2001), nitrogen-containing compounds (Okuyama et al, 1989) and steroidal saponins (Jiang, Wang, Yao, & Susumu, 1998;Matsuura, Ushiroguchi, Itakura, & Fuwa, 1989;Peng, Yao, Tezuka, Kikuchi, & Narui, 1996), among which steroidal saponins are believed to account for a variety of biological activities, such as antitumour (Baba et al, 2000;Yu et al, 2015), anticoagulation (Jiang et al, 1998), cardioprotective (Kuroda, Mimaki, Kameyama, Sashida, & Nikaido, 1995;Ren, Qiao, Yang, & Zhou, 2010), and cyclic AMP phosphodiesterase inhibitory activities (Kuroda et al, 1995).…”

Fermentation of Allium chinense Bulbs With Lactobacillus plantarum ZDY 2013 Shows Enhanced Biofunctionalities, and Nutritional and Chemical Properties

“…Apart from its medicinal use, A. chinense contains abundant proteins, carotene, vitamins, amino acids, gallic acid, and carbohydrates (Bah and others ). Similar to other members in the Alliaceae family, many sulfur‐containing compounds, such as sulfides, disulfide, and trisulfide compounds, have also been detected in A. chinense (Pino and others ). However, these compounds account for strong pungent odor, and thus limit its popularity as a table dish.…”
