ABSTRACT: The Chrysanthemum is a well-known traditional Chinese medicinal herb which has been used as a drug for thousands of years. From the detailed literature survey it is determined that the dried flowers of Chrysanthemum contain organic groups such as alkanes, flavonoids, terpinoids, unsaturated fatty acids and polysaccharides which belongs to Secondary constituents in Phytochemicals classification. The knowledge and analysis of bioactive compounds present in the Chrysanthemums can be used for next generation drug development process. The developments of new drugs against diabetes and prostate cancer have become global concern. Hence the present study leads to identify the new strategies which are needed to develop multi-functional drugs against various human diseases using Chrysanthemum plant. Owing to antifungal, antibacterial and anti-inflammation activities, Chrysanthemum have much attention in the field of biomolecules research. In general Phytochemicals can be classified as primary and secondary constituents. One can understand the fascinating properties of biological compounds via phytochemical analysis which are present in the plants. Therefore, the present study gives a better understanding of phytochemical properties of Chrysanthemum and new foundations for the production of non-toxic and eco-friendly drugs of today and the future.

Introduction

Chrysanthemums have a wide range of applications such as efficient drugs for various diseases in traditional medicinal field, healthy herbal tea in food processing, hardy blooms in gardening, and indoor air pollution control in environmental monitoring. In addition to the above appearance, aroma and color of the Chrysanthemums are the main attractive features to researchers. Aroma plays a vital role in determination of quality and market price of Chrysanthemums.  Traditional medicines from these plants have promising properties in improving liver function, decreasing inflammation. These perennial flowering plants are commonly available in Asia, northeastern Europe and most species originate from East Asia1,2. According to the literature survey more varieties of Chrysanthemums are mainly cultivated in china such as Shen-nong Sweet Chrysanthemum, Tender Huang-ju, Chamomile Flower, Hangzhou White Chrysanthemum, Florists Chrysanthemum, etc3-5. Chrysanthemum plants belong to Asteraceae family which has low molecular components include flavonoids6, sesquiterpenes7, triterpenes8, and unsaturated fatty acids9. The volatile chemical compounds of Chrysanthemum essential oil are mainly composed of monoterpenes, sesquiterpenes, aldehydes, acids, esters and alcohols 10-12. Recently, some researchers have paid more attention to characterize the aroma compounds of flowers and essential oils. Xia et al.,13 used GC–MS to analyze the volatile chemical composition from Chrysanthemum. C.morifolium is a most widely used hardy variety, available in many colours which are a better choice for gardens.

Phytochemicals of Chrysanthemum spp

Phytochemicals are biologically active chemical compounds which are derived from plants. They have many health benefits for humans further than those attributed to macronutrients and micronutrients. They play a key role to protect plants from pathogenic infections and damage. Plants have different types of phytochemicals such as Phenolic Acids, Flavonoids and Lignans which contribute to the plant’s color, aroma and flavor. Phytochemicals accumulation takes place in different parts of the plants, such as roots, stems, leaves, flowers, fruits and seeds14. More than 4,000 phytochemicals have been cataloged15 and are classified by protective function, physical characteristics and chemical characteristics16. From the survey of more than 80 research papers it is estimated that About 150 phytochemicals have been studied in detail. Chrysanthemum spp. Leaf contains octa-cosyl alcohol, β-sitosterol, lupeol, α-amyrin, daucosterol, ineupatorolide B, syringin, chlorogenic acid, petasiphenol, physcion, acacetin, eupatilin, quercetin, diosmetin, luteolin, apigenin, apigenin- 7-O-β-D-glucopyranoside, quercetin-3-O-β-D-glucopyranoside, luteolin-7-O-β-D-gluco pyranoside, apigenin-7-O-β-D- neospheroside, and acacetin-7-O-β-D-glucoside. Most of the Chrysanthemum spp flowers contain anthocyanins, cyanidin 3-glucoside and cyanidin 3-(3″-malonoyl) glucoside and carotenoids: lutein, zeaxanthin, β-cryptoxanthin, 13-cis-β-carotene, α-carotene, trans-β-carotene, and 9-cis-β-carotene. The major volatile compounds present in the plants are camphor, α-pinene, chrysanthenone, safranal, myrcene, eucalyptol, 2,4,5,6,7,7ab-hexahydro-1H-indene, verbenone, β-phellandrene and camphene. Recent studies reported by several researchers about phytochemicals found in leaves, flower and essential oil from Chrysanthemum spp are showed in table 1.

Recently, chrysanthemum flowers are known as a unique class of material which possess nutritional rich contents such as chlorophyll, carotenoids, soluble sugar, amino acid, vitamin C, flavonoid and chlorogenic acid at the time of bud stage and young flower stage. On the other hand, chrysanthemum flowers having great potential to produce active contents. Therefore both bud stage and young flower stage have been chosen as the best time for harvesting17. Ma et al., 2016
A fundamental understanding study has been made for the optimal time of harvesting of chrysanthemum flowers. From the analysis it is concluded that at the early flower opening stage, the contents of flavonoids and volatile oil were higher. On the other hand the content of chlorogenic acid, luteolin, 3,5-O-dicaffeoyl quinic acid were higher in the middle of the flowers. From the overall analysis 50% -80% fowers blossoming stage was attributed as the optimal time for harvest18. Wu et al., 2016
Generally, α-pinene, β-thujene, α-terpinolen, β-cubebene, caryophyllene, (Z)β-farnesene, (-)-spathulenol, linalool, camphor, camphene, 4-terpineol, Z-citral and 4-isopropyltoluene are typical aroma compounds covered with characteristic aroma of Chrysanthemum essential oils19. Xiao et al., 2016

Biological activities of Chrysanthemum sppThe phytochemicals play a significant influence to prevent diseases and promoting health has been studied extensively to establish their efficacy. Identification and isolation of the chemical components, establishment of their biological potency carried out by many researchers both in vitro and in vivo studies have been analyzed through literature survey. From this review, the experimental details reported in literatures which are done in animals, through epidemiological and clinical-case control studies in man are clearly described in table 2. Overproduction of free radicals can induce many human diseases such as diabetes, cancer, stroke, rheumatoid arthritis and atherosclerosis37-39. Antioxidants can alleviate the oxidative stress, which is beneficial for human health40. However, some currently used synthetic free radical scavengers have been demonstrated various side effects41,42. Therefore, functional foods become a promising source of natural antioxidants43,44. It is noteworthy to mention here that Chrysanthemum spp. has many health and medicinal properties such as Antioxidant, skin cancer, antimicrobial activities and various bone diseases. Recent studies on biological activities of Chrysanthemum spp reported by various researchers are shown in table 2
