Chemical Investigations on Celastrus paniculatus Seed Oil I

AbstractFatty acid compositions of four lipid fractions of Celastrus paniculatus seed namely normal triglycerides (20.2%), polar triglycerides (44.4%), polar nonglyceridic ester (23.5%), and nonpolar nonglyceridic ester (11.9%), have been determined by gas liquid chromatography. Percentage contents of major component acids in these fractions are: palmitic, 25.1, 42.0, 12.7, 58.2; stearic, 6.7, 4.5, 15.8; oleic, 46.1, 24.8, 4.7, 14.2; linoleic, 15.4, 14.7, 10.0; and linolenic, 3.0, 13.1, 43.0, respectively. The major molecular species constituting the normal triglycerides are: palmitooleopalmitin, 6.8%; palmitooleostearin, 5.6%; palmitodiolein, 14.7; palmitooleolinolein, 7.0%; stearodiolein, 6.1%; triolein, 8.0% and dioleolinolein 7.6%. Lipolysis of the polar triglyceride indicated as high as 59.6% of saturated acids linked to the 2‐position of glycerol.

Struktur und stereochemie eines sesquiterpen-esters und dreier sesquiterpen-alkaloide von Celastrus paniculatus Willd

A new sesquiterpene ester (Malkangunin) and three sesquiterpene alkaloids (Celapanin, Celapanigin, Celapagin) were isolated from Celastrus paniculatus Willd. The complete structure and stereochemistry of Malkangunin, a sesquiterpene tetra-ol of the β-dihydroagarofurane type two of whose hydroxyls being esterified with acetic and benzoic acids, is discussed. The alkaloids described here are derived from a new sesquiterpene tetra-ol (Celapanol) which is alternately esterified with acetic, benzoic, nicotinic and β-furoic acids.

Chemical investigation of the seed fat of Celastrus paniculatus

AbstractThe fatty acid composition of the seed fat of Celastrus paniculatus was determined by spectrophotometry, urea adduct formation and quantitative paper chromatography. The percentages of individual acids were found to be: formic, 1.5; acetic, traces; benzoic, 3.4; palmitic, 31.2; stearic, 3.5; oleic, 22.5; linoleic, 15.7; and linolenic, 22.2. A solid ester (m.p. 60–62°c), isolated from the seed fat, has been partly characterised by chromatography and spectral analysis.

Comparative Antioxidant Potential of Different Extracts of <i>Celastrus paniculatus</i> Willd. Seed

The objective of the present study was to evaluate the comparative antioxidant potential of methanol, ethyl acetate, pet ether and water extracts of Celastrus paniculatus seed. Antioxidant activity was evaluated by using total phenol and flavonoid content determination assays, total antioxidant capacity, 1,1-diphenyl-2- picryl-hydrazil (DPPH) free radical assay, Reducing power assessment, Nitric oxide (NO) scavenging assay and Cupric ion reducing capacity assay (CUPRAC method). The extracts showed moderate antioxidant activity in a dose dependent manner. The extracts were found to contain phenolics and flavonoid compounds. In DPPH radical scavenging assay, ethyl acetate extract had the lowest IC50 value (585.58μg/ml) compared to ascorbic acid. In nitric oxide scavenging assay IC50 value was found to be 122.99μg/ml, 320.54μg/ml, 601.81μg/ml and 206.37μg/ml respectively for the Water, Methanol, Ethyl Acetate and Pet Ether extracts compared to 6.83μg/ml which was the IC50 value for the reference ascorbic acid. The extracts also showed good reducing power. The results of the present study indicate that the extracts possesses significant antioxidant potential of which ethyl acetate extract is the most promising one and possess highest antioxidant potential.

EPIDERMAL STRUCTURE AND STOMATAL ONTOGENY IN SOME CELASTRACEAE

SummaryLeaves of Celastrus paniculatus, C. stylosus, Elaeodendron glaucum, Euonymus japonicus and E. pendulus are essentially hypostomatic, although a few stomata were observed near veins in the upper epidermis of Celastrus paniculatus. Their irregularly orientated stomata show guard cells partly underarched and partly surrounded by a ring of three to eight subsidiary cells. Surface walls of epidermal cells in Euonvmus pendulus show pits whose impressions are also seen in the cuticle.Rehfous (1914) had suggested that the sunken subsidiary cells of Celastrus europaeus, Catha edulis and Euonymus japonicus and four other species of the genus are formed in an unusual manner from segments of the guard cells. Our studies on the contrary indicate that the subsidiary cells in all our plants, including E. japonicus, are typically perigene.Mesophyll of all leaves is armed but the form of midrib bundles varies in different species and to some extent in different regions of the same leaf.

The care of leather

Celastrus paniculatus Willd. is an important Indian medicinal plant and widely used in the treatment of the verity of disease and well explored scientifically for their pharmacological properties. The current study was therefore carried out to provide requisite pharmacognostic details about the plant.Pharmacognostic investigation of the fresh, powdered and anatomical sections of the leaves of Celastrus paniculatus Willd. was carried out to determine its morphological, anatomical, and phytochemical diagnostic features. Quantitative diagnostic characteristics, physicochemical properties and quantitative phytochemical measures were established.The morphology of leave reveled, leaves are alternate, acute, acuminate or obtuse, rounded with cuncate base,; margin is finely crenate, venation is reticulate. The microscopy reveals the dorsiventral type of leave, with anomocytic stomata, covering (lower epidermis) and glandular (upper epidermis) trichomes. The collateral vascular bundle crowned with sclerenchymatous fiber, ideoblast of calcium oxalate. The Quantitative diagnostic characteristics such as leaf constant were measured. Physicochemical properties such as ash, extractive values and fluorescence analysis were established. Quantitative phytochemical revealed presence of carbohydrates, fixed oil, glycosides, cumarines, tannins, flavonoids, saponins, steroids and triterpenoids.The results of the study could be useful in setting some diagnostic indices for the identification and preparation of a monograph of the plant.
