Spring 2024 Revision Lecture 1 PPC102_Medicinal Seeds 2 1. Semen Trigonellae (Fenugreek) ❑ Botanical origin The dried seeds of Trigonella foenum-graecum L., family Fabaceae ❑ Description https://www.walmart.com/ip/Fenugreek-Seeds-Whole/356344529 The very hard seeds have a strong characteristic odour and are irregularly rhomboidal and oblong or square in outline. They are somewhat flattened and are divided into two unequal parts by a groove in the widest surfaces. https://chestofbooks.com/health/materia-medica-drugs/Textbook-Materia-Medica/Fenugreek-Seeds-Semina-Foeni-Graeci.html PPC102_Medicinal Seeds 3 ❑ Active constituents ✓ Pyridine-type alkaloid trigonelline N.B.) it serves as the reference substance for the BP/EP TLC identification test for the drug ✓ Steroidal sapogenin Diosgenin (oily embryo) ✓ A non-essential amino acid, 4-hydroxyisoleucine, which constitutes up to 80% of the free amino acid composition of fenugreek seeds and has been shown to possess insulin-stimulating properties both in vitro and in vivo ✓ Fixed oil (5-10 %) ✓ Mucilage 24 % (galactomannans) N.B.) Based on mucilage content, the BP/EP sets a swelling index of not less than 6.0 for the powdered seeds PPC102_Medicinal Seeds 4 PPC102_Medicinal Seeds 5 ❑ Uses and therapeutic applications ✓ Fenugreek may help stimulate breast milk production and ease the flow (Lactagauage) ✓ It improves insulin sensitivity and action (antidiabetic effect) ✓ It improves weight loss N.B.) Fenugreek may suppress the appetite and increase feelings of fullness, which could help reduce overeating and lead to weight loss. ✓ Raise testosterone and boost sperm count ✓ Antioxidant and anti-inflammatory ✓ Diosgenin is used for the commercial synthesis of steroid products (cortisone, progesterone, etc.) e.g., for contraceptive pills. PPC102_Medicinal Seeds 6 2. Semen Psyllii (Psyllium) ❑ Botanical origin The dried, ripe seeds of Plantago afra (P.psyllium), P.indica (P.arenaria) and P. ovata Family, Plantaginaceae. ✓ Common names: Planatgo seeds, Flea seeds https://www.indiamart.com/proddetail/psyllium-seed-10510674573.html N.B.) The US National Formulary includes all three species under the name ‘Plantago Seed’. The BP/EP describes the seeds of the first two species under the title ‘Psyllium’ and the husks of seeds of P. ovata are included under ‘Ispaghula Husk’. The latter consists of the epidermis and collapsed adjacent layers removed from the ripe seeds. PPC102_Medicinal Seeds 7 ❑ Uses ✓ Plantago seeds are used as demulcents and in the treatment of chronic constipation. ✓ Plantago seeds might help in weight loss ✓ Ispaghula husk is used for similar purposes but has a higher swelling factor (40–90). Mechanism o Mucilage increases the bulk in the stool, an effect that helps to cause movement of the intestines. o It also works by increasing the amount of water in the stool, making the stool softer and easier to pass. N.B.) Psyllium, one type of bulk-forming laxative, has also been used along with a proper diet to treat high cholesterol. ✓ It is commonly used as a food ingredient in manufactured breakfast cereals. ❑ Dose o Doses of 5–10 g of Psyllium husk, three times per day o Also, psyllium could delay the absorption of certain medications, therefore, doctors often recommend that people avoid taking it with other medicines. PPC102_Medicinal Seeds 8 3.

PPC102_Medicinal Seeds 9 ❑ Constituents ✓ Fixed oil (30-40 %) ✓ Mucilage (6 %), (BP swelling index for whole seeds not less than 4.0) ✓ Proteins (25%) ✓ Small quantities of the cyanogenetic glucosides linamarin and lotaustralin ✓ Lignans: (–)-pinoresinol diglucoside ✓ Lignan precursor: secoisolariciresinol diglucoside PPC102_Medicinal Seeds 10 ❑ Linseed oil The extraction of linseed oil is done mechanically via a mill, and the remaining cake is used as a cattle food. Physical characters Linseed oil of BP quality is a yellowish-brown drying oil with a characteristic odor and bland taste; much commercial oil has a marked odor and acrid taste. On exposure to air, it gradually thickens and forms a hard varnish It has a high iodine value (not less than 175), as it contains considerable quantities of the glycosides of unsaturated acids Types of fatty acids in linseed: ❑ Unsaturated fatty acid ✓ α-linolenic acid, C17H29COOH (36–50%) omega-3 ✓ γ-linoleic acid C17H31COOH (23–24%) omega-6 ✓ oleic acid C17H33COOH (10–18%) ❑ Saturated acids: myristic, stearic and palmitic (5–11%). PPC102_Medicinal Seeds 11 ❑ Uses ✓ Crushed linseed is used in the form of a poultice ✓ Whole seeds are employed to make demulcent preparations ✓ The oil is used in liniments, and research has suggested that hydrolysed linseed oil has potentially useful antibacterial properties as a topical preparation in that it is effective against Staphylococcus aureus strains resistant to antibiotics ✓ Linseed cake is a valuable cattle food ✓ Cardioprotective effect (due fatty acids) ✓ May reduce cancer risk, (due to lignans) ✓ May aid weight control ✓ May reduce blood sugar level ✓ May lower cholesterol level (help in atherosclerosis, due to omega-3 fatty acids) PPC102_Medicinal Seeds 12 Lecture 2 PPC102_Medicinal Seeds 1 3 4.

Both nutmeg and mace are used for flatulence, and reducing nausea and vomiting Allied drugs. Bombay nutmegs are derived from M. malabarica, grown in India. They are very long and narrow and lack the characteristic aroma of the genuine drug. PPC102_Medicinal Seeds 17 Nutmeg seed myristicin The psychotropic potential of myristicin is related to its metabolism into (3-methoxy-4,5-methylenedioxyamphetamine) (MMDA), an amphetamine derivative that is reported to have a more potent hallucinogenic effect. MMDA Note: Minimum dosage of nutmeg that can cause psychogenic effect is 5 g (ground nutmeg) with 1 to 2 mg myristicin content and this dosage is considered as 'toxic dose'.
