The pharmacological properties of two new alkaloids of Rauwolfia serpentina have been studied with special reference to their cardiovascular actions. In several instances, comparative studies have been carried out with the clinically used alseroxylon fraction of R. serpentina. Chandrine and serpakrine do not profoundly influence the activity or behavior of intact animals unless administered in very large doses. They are completely devoid of the tranquilizing action that characterizes such bases as reserpine and rescinnamine. They do, however, exhibit marked hypotensive activity. The mechanism of this depressor action has not been clearly established. It is not seen in spinal animals, and there is no evidence of ganglionic blocking or peripheral adrenolytic action. The effects of chandrine or serpakrine per se on smooth muscle structures are not pronounced, but antiacetylcholine activity has been observed on these and other preparations. Their contribution to the actions of the clinically employed whole-root extracts is probably not very marked.

The Eugenia and Syzygium genera include approximately 1000 and 1800 species, respectively, and both belong to the Myrtaceae. Their species present economic and medicinal importance and pharmacological properties. Due to their chemical diversity and biological activity, we are reporting the essential oils of 48 species of these two genera, which grow in South America and found mainly in Brazil. Chemically, a total of 127 oil samples have been described and displayed a higher intraspecific and interspecific diversity for both Eugenia spp. and Syzygium spp., according to the site of collection or seasonality. The main volatile compounds were sesquiterpene hydrocarbons and oxygenated sesquiterpenes, mainly with caryophyllane and germacrane skeletons and monoterpenes of mostly the pinane type. The oils presented many biological activities, especially antimicrobial (antifungal and antibacterial), anticholinesterase, anticancer (breast, gastric, melanoma, prostate), antiprotozoal (Leishmania spp.), antioxidant, acaricidal, antinociceptive and anti-inflammatory. These studies can contribute to the rational and economic exploration of Eugenia and Syzygium species once they have been identified as potent natural and alternative sources to the production of new herbal medicines.

Objective: In today’s scenario, the herbal medicines are much efficient for the treatment of various disorders as they have minimal side effects incomparison to the allopathic medicines. Bauhinia variegata L. (Mountain Ebony), commonly called Kachnar, belongs to the family Leguminosae.It is a medium-sized tree, mostly found at an altitude of 1300 m in the Himalayas. The objectives of the present study are to investigate variouspharmacognostic, phytochemical analysis, and pharmacological properties of B. variegata.Methods: The powdered drug was used for estimating the loss on drying, ash values, fluorescence studies, chemical tests, and extractive values.Macroscopic and microscopic studies were also performed.Results: The leaf microscopy revealed the presence of upper and lower epidermis, palisade tissue, well-developed vascular bundle. The fluorescencecharacteristics of leaf powder were studied both in visible light and ultraviolet light (254 nm and 365 nm) after treatment with various reagents.Kachnar is composed of carbohydrates, tannins, alkaloids, flavonoids, amino acid. It was reported that the total ash value was 8.15%. The acidinsoluble ash value was 5.5%.Conclusion: The main pharmacological activities of B. variegata are anthelmintic, antiulcer, antitumor, antimicrobial, antidiabetic, anti-inflammatory, antigoitrogenic, and hepatoprotective. The present investigation provides the information on its pharmacognostic, phytochemical analysis, andpharmacological properties.Keywords: Flavonoids, Kachnar, Alkaloids, Antioxidant, Leguminosae.

Objective: Now-a-days, the herbal medicines are much efficient for the treatment of various disorders as they have minimal side effects in comparison to the allopathic medicines. Cassia angustifolia, commonly called Senna belongs to the family Leguminosae and is a well-known laxative throughout the world. Senna is mostly found in Tirunelveli, Madurai, and Ramnathpuram districts of Tamil Nadu. Carbohydrates, tannins, alkaloids, flavonoids, and amino acid are the important chemical constituents of C. angustifolia. The objectives of the present study are to investigate various pharmacognostic, phytochemical analysis, and pharmacological properties of C. angustifolia.Methods: The powdered drug was used for estimating the loss on drying, ash values, fluorescence studies, chemical tests, and extractive values. Macroscopic and microscopic studies were also performed.Results: The transverse section (T.S). of leaf showed isobilateral structure along with paracytic stomata, nonlignified unicellular trichomes with warty walls, and fibrovascular bundle. The fluorescence characteristics of leaf powder were studied both in visible light and ultraviolet (UV) light (254 nm and 365 nm) after treatment with various reagents. Senna is composed of carbohydrates, tannins, alkaloids, flavonoids, and amino acid. It was reported that the total ash value was 11.23±0.25 w/w. The acid insoluble ash value was 1.4±0.1% w/w. Water soluble, ethanol, methanol, petroleum ether, and chloroform extractive values were 16.6±0.26% w/w, 3.7±1.75% w/w, 0.83±0.05% w/w, 1.6±0.1% w/w, and 3.2±0.25% w/w, respectively.Conclusion: The main pharmacological activities of Bauhinia variegata are anthelmintic, antiulcer, antitumor, antimicrobial, antidiabetic, anti-inflammatory, antigoitrogenic, and hepatoprotective. The present investigation provides the information on its pharmacognostic, phytochemical analysis, and pharmacological properties.

Background: Vatsanābha, (Aconitum ferox Wall., Ranunculaceae), has been well documented in Ayurvedic texts such as Saṁhitā (treatise), Nighaṇṭu (lexicons), Rasagranthas (compendia related to alchemy) and Cikitsā granthas (compendia of Ayurveda). Methods: This paper provides a collective information regarding Vatsanābha, its morphological characters, properties and actions mentioned in Nighantu, Samhita and Rasagrantha. Result and discussion: The study reveals that Vatsanābha, a medicinal plant has about forty-one synonyms (paryaya); and highlightes its morphological characters and pharmacological properties. It is attributed with properties like Vyavāyī (CNS stimulation followed by depression), Balya (tonic), Rasāyana (Rejuvenation), Kaṇṭharukhara (reliever of throat pain), etc. As a single drug, Vatsanābha is indicated in about twenty-seven clinical conditions like Agnimāndhya (digestive impairment), Kāsa (cough), Madāvaha (alcoholism), Gulma (abdominal lump), etc. Vatsanābha is used for Śodhana (purification procedure), krāmaṇa (transformation of base metals into gold) and Vedhana (alchemy); 3 saṅskāra among the aṣṭasaṅskāra of pārada. Conclusion: This review may enrich to documentary research and may provide collective and detailed information regarding Vatsanābha as it is presented in ayurvedic classical texts.
