“…Hedychium coronarium (commonly known as white ginger lily or butterfly ginger) is a perennial herb of the Zingiberaceae family. It has become a popular landscape plant or cut flowers in tropical and subtropical areas worldwide owing to its distinct and beautifully perfumed flower (Shanmugam et al, 2015 ; Chen et al, 2019 ). The inviting and pleasant fragrance of its fresh flower mainly results from volatile benzenoids and monoterpenes, like methyl benzoate, linalool, and ( E )-β-ocimene (Baez et al, 2011 ; Yue et al, 2015 ).…”

Methyl benzoate is a constituent of floral scent profile of many flowering plants. However, its biosynthesis, particularly in monocots, is scarcely reported. The monocot Hedychium coronarium is a popular ornamental plant in tropical and subtropical regions partly for its intense and inviting fragrance, which is mainly determined by methyl benzoate and monoterpenes. Interestingly, several related Hedychium species lack floral scent. Here, we studied the molecular mechanism of methyl benzoate biosynthesis in H. coronarium. The emission of methyl benzoate in H. coronarium was found to be flower-specific and developmentally regulated. As such, seven candidate genes associated with methyl benzoate biosynthesis were identified from flower transcriptome of H. coronarium and isolated. Among them, HcBSMT1 and HcBSMT2 were demonstrated to catalyze the methylation of benzoic acid and salicylic acid to form methyl benzoate and methyl salicylate, respectively. Methyl salicylate is a minor constituent of H. coronarium floral scent. Kinetic analysis revealed that HcBSMT2 exhibits a 16.6-fold lower Km value for benzoic acid than HcBSMT1, indicating its dominant role for floral methyl benzoate formation. The seven genes associated with methyl benzoate biosynthesis exhibited flower-specific or flower-preferential expression that was developmentally regulated. The gene expression and correlation analysis suggests that HcCNL and HcBSMT2 play critical roles in the regulation of methyl benzoate biosynthesis. Comparison of emission and gene expression among four Hedychium species suggested that coordinated and high-level expression of biosynthetic pathway genes is responsible for the massive emission of floral methyl benzoate in H. coronarium. Our results provide new insights into the molecular mechanism for methyl benzoate biosynthesis in monocots and identify useful molecular targets for genetic modification of scent-related traits in Hedychium.

BackgroundZongzi, a common Chinese rice-pudding and one of the most symbolic foods in traditional Chinese festivals, is integral to both Chinese traditional culture and daily meals. Traditionally, the leaves of different plant species have been used to wrap zongzi. The variety of zongzi leaves (ZLs) can contribute to the zongzi-based cultural diversity. Given the cultural and dietary significance of zongzi, the ethnobotanical surveys were carried out, aiming to investigate the diversity of plant species and associated traditional botanical knowledge of ZLs, which could attract particular attention for their further studies.MethodBoth literature studies and field surveys were conducted in the study. The field investigations were carried out from May 2006 to June 2018 throughout China. Ethnobotanical information about ZLs was obtained by direct observation, semi-structured interviews, and key informant interviews.ResultsIn total, ZLs from 57 plant species were identified and recorded, belonging to 38 genera and 18 families. Several folk legends have been formed to explain the origin of using plant leaves to pack zongzi. Over time, Chinese people have developed diverse traditional botanical knowledge surrounding ZLs, especially regarding the zongzi flavor, antiseptic functions, and medicinal values. Based on the literature review, some species of ZLs such as the leaves of Corchorus capsularis and Vernicia fordii may even pose a potential threat to human health. Presently, in some regions of China, the traditional ZLs, such as Cocos nucifera, Tilia tuan, and Zizania latifolia, are being substituted by commercialized ZLs such as Phragmites australis and Indocalamus tessellatus.ConclusionA variety of traditional ZLs have been discovered in China. Although diverse traditional knowledge exists in China surrounding the usage of ZLs, some species may have the potential of threatening human health. Therefore, further explorations are necessary to comprehensively evaluate traditional ZLs, the results of which could help to conserve the cultural diversity of zongzi, to guarantee food safety, and to encourage the uses of plant leaves in food, medicine, and environmental management, for our human health.

“…Aside from the flowers, the other parts also contain aromatic compounds. Essential oils from the rhizome, stem, and leaf of H. coronarium have been reported to be successfully extracted and contain a variety of volatile constituents [18]. Hence, various parts of H. coronarium, including the rhizomes, leaf sheaths, and leaves, were used in the present study.…”

This study aimed to extract aromatic compounds from the rhizomes, leaf sheaths, and leaves of Hedychium coronarium and investigate their chemical compositions, cosmetic/cosmeceutical activities, and irritation potency. The chemical compositions were investigated via gas chromatography–mass spectrometry. The antioxidant activities were evaluated via spectrophotometry. The anti-skin wrinkle properties were investigated via collagenase, elastase, and hyaluronidase inhibition. The irritation potency was observed via a hen’s egg–chorioallantoic membrane test. Eucalyptol was detected as a major component in the rhizomes and leaf sheaths, while β-caryophyllene was predominant in the leaves. The absolutes from the rhizomes were the strongest antioxidants, with ABTS scavenging properties similar to L-ascorbic acid. Interestingly, the equivalent concentration (EC1) of the absolute from the rhizome was 0.82 ± 0.01 µg FeSO4/g extract, which was significantly more potent than L-ascorbic acid (0.43 ± 0.03 µg FeSO4/g extract). The rhizome-derived absolute was the most effective against collagenase, while the concretes from the rhizomes and leaf sheaths showed promising anti-hyaluronidase activity with inhibitions of 90.5 ± 1.6% and 87.4 ± 5.1%, respectively. The irritability of the aromatic extracts was not different from that of the vehicle control, proving their safety. Therefore, the Hedychium coronarium rhizome-derived absolute was an attractive and potent antioxidant with anti-collagenase activities, indicating its potential for use in anti-aging formulations.
