“…To be specific, EOs were dominated by mostly sesquiterpene hydrocarbons (52.83 to 65.63%) followed by sesquiterpene alcohol (14.71 to 22.45%) ( Table 2 , Figure 1 ). The present result is also consistent with the previous literature, where the leaf essential oil of M. champaca collected from Brazil was rich in sesquiterpene hydrocarbons followed by oxygenated sesquiterpenes [ 24 ]. In all the populations, the major constituents were β-elemene, γ-muurolene, β-caryophyllene, germacrene B, n-hexadecanol, α-humulene, viridiflorene, bicyclogermacrene, methyl linoleate, linalool, etc.…”

“…Similarly, the lowest essential oil yield was found in the accessions MCL3 and MCL4 (0.06% v / w ) which were collected from the Bhadrak district. The essential oil yield of M. champaca in the present study was higher than that of the previous report [ 24 ], which reported an EO yield of 0.04% in fresh leaves collected from Brazil in different seasons. Further, the resulting variations in the essential oil yield might be due to seasonal variation, geographical location, genetic and environmental factors, etc., as reported in other species [ 2 , 3 , 4 ].…”

“…In spite of having enormous potential, few reports are available on phytoconstituent analysis of the leaf essential oil of M. champaca [ 24 , 25 ]. The available reports show that the M. champaca leaf essential oil is rich in sesquiterpenoids such as β-elemene, β-caryophyllene, α-humulene, β-selinene, and α-selinene, etc.…”

Magnolia champaca (L.) Baill. ex Pierre of family Magnoliaceae, is a perennial tree with aromatic, ethnobotanical, and medicinal uses. The M. champaca leaf is reported to have a myriad of therapeutic activities, however, there are limited reports available on the chemical composition of the leaf essential oil of M. champaca. The present study explored the variation in the yield and chemical composition of leaf essential oil isolated from 52 accessions of M. champaca. Through hydrodistillation, essential oil yield was obtained, varied in the range of 0.06 ± 0.003% and 0.31 ± 0.015% (v/w) on a fresh weight basis. GC-MS analysis identified a total of 65 phytoconstituents accounting for 90.23 to 98.90% of the total oil. Sesquiterpene hydrocarbons (52.83 to 65.63%) constituted the major fraction followed by sesquiterpene alcohols (14.71 to 22.45%). The essential oils were found to be rich in β-elemene (6.64 to 38.80%), γ-muurolene (4.63 to 22.50%), and β-caryophyllene (1.10 to 20.74%). Chemometrics analyses such as PCA, PLS-DA, sPLS-DA, and cluster analyses such as hierarchical clustering, i.e., dendrogram and partitional clustering, i.e., K-means classified the essential oils of M. champaca populations into three different chemotypes: chemotype I (β-elemene), chemotype II (γ-muurolene) and chemotype III (β-caryophyllene). The chemical polymorphism analyzed in the studied populations would facilitate the selection of chemotypes with specific compounds. The chemotypes identified in the M. champaca populations could be developed as promising bio-resources for conservation and pharmaceutical application and further improvement of the taxa.

“…The growing season for this plant mainly is monsoon from June to September 22 . This Plant is rich in volatile oil constituents, concentration of which vary due to seasonal variation like sesquiterpene content are found be constant in concentration during January, March, May, July, December about (5-7%) and 21% in September and terpenoid derivatives like aliphatic C 15 and C 16 alcohol have constant amount (14-17%) all over the year 23 . 1 which help in the identification of this plant either in strength and purity 26 .…”

Michelia Champaca Linn., belonging to family Magnoliaceae, is commonly known as Champa. It is a medium size evergreen tree highly distributed in eastern Sub-Himalayan tract, West Bengal, Myanmar, and South India in addition to China. This plant is useful either as an ornamental purpose or as traditional ethnomedicine. Now, the purpose of this article is to describe the pharmacognostic, pharmacological and chromatographic profile of this plant. This article provides the collective information about the phytochemical constituents isolated from various parts of this plant used in a modern scenario for the treatment of various ailments like β-sitosterol, sesquiterpenes, parthenolide, dihydro parthenolide, gallic acid, quercetin, liriodenine, essential oils, starch, etc. Traditional uses of the plant in the treatment of various disease like rheumatism, gout, diuretic, febrifuge, etc. This article also gives information about reported pharmacological activities such as anti-diabetic, anti-microbial, anti-inflammatory, diuretic, anti-ulcer, analgesic, burn wound healing, antihelmintholytic, Procognitive activity, anti-oxidant and some other activities. INTRODUCTION:M. champaca Linn. belonging to the family (Magnoliaceae) is an evergreen plant mainly cultivated in Indian gardens and near temples for its fragrant flowers and handsome foliage 1 . In the traditional system of medicines, plants are the primary source for the treatment of various ailments. Michelia is the genus consisting of 80 species distributed throughout the tropical and subtropical region and of which about 70 species are native to China and found in southwestern and eastern mountainous region 2 . One of these 80 species, M. champaca which is commonly known as Champa in Hindi; Champaka in Bengali; Atigandhaka in Sanskrit 3 .

“…The quercetin forms the first report of its occurrence in the genus Michelia (Shalini and Jaggi , 2004). Lago et al (2009) reported that volatile oils contained six sesquiterpene hydrocarbons, four oxygenated sesquiterpene, and two aliphatic alcohols from water using dichloromethane solvent in leaves of M.champaca L. There appears to be no Pharmacognostical work of this valued (leaves and flowers) traditional medicinal plant. In the present study, Pharmacognostical evaluations of leaves and flowers of Michelia champaca L. provided useful information with regard to its proper identity and may help to differentiate from the closely related species of Michelia.…”

The present investigation was conducted to establish pharmacognostical profile for the leaves and flowers of Michelia champaca L. (Magnoliaceae) in order to establish its complete profile to aid in its identification and avoid confusion in taxonomic level for different species of the same genus. The study included macroscopical, organoleptical, microscopical and preliminary phytochemical analysis of the leaves and flowers. The study of the organoleptical evaluation revealed the presence of colour, odour and texture. The microscopic analysis showed the differences in cell structures, arrangement and shape of leaves and flowers. The physical characters of various solvent extracts showed the presence of colour, odour and consistency of the powdered leaves and flowers. Finally, the preliminary phytochemical analysis confirmed for the presence of alkaloids, saponins, tannins, glycosides, carbohydrates, amino acid, flavonoids and sterols in both leaves and flowers. The present findings may be used to establish the authenticity of leaves and flowers of Michelia champaca L. for their proper identification and standardization in order to collect raw plants for the preparation of herbal drugs.
