  1. Nomenclature in Latin • Castaneasativa, sweetchestnut. • Sativum, Sativus, andSativa - adjectivesmeaningcultivated, • Sativaderivedfromthe Latin satum, meaningtosow.  • 'season' derivesalsofromsatum, as 'appropriate time forsowing'.  • Sativaends in -a, because it is thefeminine form of theadjective, • masculine (-us) andneuter (-um) endingsareusedtoagreewiththegender of thenouns • Crocussativus – Saffron (masculine), Pisumsativum– Pea (neuter). • Ranunculus=buttercupmuricatus=rough • Sinapis=Mustardarvensis =in thefields. M.S. IQBAL,A. GHAFOOR, INAMULLAH, H.AHMAD. 2013. Pak. J. Bot., 45(6): 2065-2070. GENETIC VARIATION IN YIELD PERFORMANCE FOR THREE YEARSIN NIGELLA SATIVA L. GERMPLASM AND ITS ASSOCIATIONWITH MORPHO-PHYSIOLOGICAL TRAITS AND BIOCHEMICAL COMPOSITION.

  2. GRAPES • Domesticationbegan 6,000–8,000 years ago in the Near East-cultivation in Asia 5000 BC. • OftentheMediterranean as thehomeforallgrapes, actuallynativetoregions in Asia, Africa, North America.

  3. Most widely cultivatedgrapespecies-  Vitis vinifera (Asia-1 native grape Amur grape Vitis amurensis ), & several 1000 var. of this grape exist. • Earliest archeological evidence- 8,000 years ago from Georgia. • Yeast, earliest domesticated microorganism- occurs naturally on the skin of grapes, leading to the alcoholic drinks.

  4. ACTIVE COMPOUNDS: • Stilbenes: • resveratrol, piceatannol, pterostilbene. • Flavanols: • catechins, epicatechins, procyanidins,proanthocyanidins,viniferonesquercetin,myricetin, • kaempferol , isorhamnetin. Phenolic Acids, • caffeic acid,coumaric acid,ferulic acid,gallic acid. • Carotenoids : • beta-carotene, lutein, zeaxanthin.

  5. Gene-Mapping Project-heritage of over 110 modern grape cv –investigatedorigin in Georgia-residues discovered on the inner surfaces of 8,000-year-old ceramic storage jars. • Armenia, datingtoaround 4000 BC. • Syrahredwine of ShirazcalledShiraziwineknownfrom 16 AD.

  6. Egyptian hieroglyphics record the cultivation of purplegrapes. • Greeks,Phoeniciansand Romans grewforeating + wine production. • In USA native grapes from various species of  Vitis genus were a part of the diet of many NativeAmericans. • BUT Vitis vinifera cvimported.

  7. FrenchParadox • French tend to eat higher levels of animal fat, but the incidence of heart disease remainslow? • Potentialbenefitsinclude: reduces platelet aggregation, compounds mainly in the grape skin provide manyhealthbenefits. • Altersmolecularmechanisms in bloodvessels, reducingsusceptibilitytovasculardamage.

  8. Decreases activity of angiotensin, a systemic hormone causing blood vessel constriction that would elevate blood pressure. • Increases production of thevasodilatorhormone, nitricoxide. • Polyphenols like resveratrolprovide physiologicalbenefits & protectiveeffects on thecardiovascular system.

  9. Resveratrol • Apparently serves antifungal & other defensive properties. • Dietary- modulates the metabolism of lipids & inhibits oxidation of low-density lipoproteins & aggregation of platelets. • primarily in theskins of grapevarieties & seeds, in muscadine grapes- have about 100 timeshigherconcentrationthanpulp.

  10. Fresh grape skin contains about 50 to 100 microgm. of resveratrol / gm. • In vitro studiesindicate-protection of thegenomethroughantioxidant actions may be a general function of resveratrol. 

  11. resveratrol-1 year dietaryregime;Phase III study of elderly patients with Alzheimer's disease. • anthocyanins-mainpolyphenolics in purplegrapes; • catechins are the more abundantphenolic in whitevarieties.

  12. resveratrol has transcriptional overlap with the beneficial effects of calorie restriction in heart, skeletalmuscle& brain (micestudies). • inhibits gene expressionassociatedwithheart&skeletalmuscleaging. • preventage-relatedheartfailure.

  13. Total phenolic content-lab. index of antioxidantstrengthhigher in purplecv (skin anthocyanindensity) comparedtowhitegrape skin (lackanthocyanins). • BUT, phenoliccontentvarieswithcv, soilcomposition, climate, geographicorigin, & cultivationpracticesorexposuretodiseases, such as fungalinfections. • Fermentation time in contact with grape skins-an important determinant of resveratrol content.

  14. Ordinary non-muscadine extract contains 0.2 - 5.8 mg/L, dependingon the grape variety. • Inmuscadineskins, ellagicacid, myricetin, quercetin,kaempferol, & trans-resveratrolaremajorphenolics. • Extractsfrommuscadinegrapesmaycontainmorethan 40 mg/L, an exceptionalphenoliccontent. 

  15. Contrary to previous results, EllagicAcid& not Resveratrolregarded as themajorphenolics in muscadine grapes. • Flavonols syringetin, syringetin 3-O-galactoside, laricitrin & laricitrin 3-O-galactosidealso found in purple, absent in whitegrapes.

  16. Benefits • Areas of benefit in graperesearchincludethecardiovascularsystem, respiratorysystem, immunesystem, inflammatorysystem, bloodsugarregulatingsystem, & nervoussystem. • Anotherarea of specialbenefit is cancerprevention, withrisk of breast, prostate, & coloncanceremerging as themostlikelyareas of grape anti-cancerbenefits.

  19. Taxusbaccata • In 1021, Avicennaintroducedthemedicinaluse of  T. baccataforphytotherapy in TheCanon of Medicine. • He namedthisherbaldrug "Zarnab" andused it as a cardiacremedy. • Firstknownuse of a calciumchannelblockerdrug, not in wideuse in the Western worlduntilthe 1960s.

  20. Precursors of chemotherapydrugPaclitaxel   derived from the leaves of European yew :-Taxusbaccata,  more renewable source than the bark of the Pacific yew (Taxus brevifolia-western yew,Taxaceae) a  conifer  native to  Pacific NW of N America. • Early 1990s; manyenvironmentalists, including Al Gore, had opposedtheharvesting of yewforpaclitaxelcancertreatments. 

  21. Docetaxel (anothertaxane) obtainedby semi-syntheticconversionfromtheprecursors. • CentralHimalayas-theplantused as a treatmentforcancer. • Chemotherapy drug paclitaxel (taxol), used in breast, ovarian, & lung cancer treatment.

  22. Had becomescarce when chemotherapeutic potential realized----never commercially harvested from itshabitat at alarge scale. • semi-synthetic pathway was developed from extracts of cultivated yewsof otherspecies. • Traditionally, wood used by native Americans to make bows& paddles for canoes, +many other items for daily life use. • Japanese used the woodfor decorative purposes.

  23. Most parts of tree toxic, except thebright red aril surrounding the seed. • Foliage toxic even when wilted, toxicity increases in potency when dried. • Ingestion & subsequent excretion by birds whose beaks+digestive systems do not break down the seed's coating are the primary means ofyew dispersal. 

  24. Taxus baccata-a conifer native to western, central, southern Europe, NW Africa, N Iran & SW Asia. • Unlicensed pharmaceutical production & use of closely related wild yew species in India +China threatening these species.

  25. Originally known as yew, now called English yew, or European yew. • A tree in Scotland, has largest recorded trunk -2,000 to 3,000 years old, may be around 1,500 yearsold. • Horses have lowest tolerance to taxine, with a lethal dose of 200–400 mg/kg body weight, cattle, pigs, & other livestock are only slightly less vulnerable.

  26. Symptoms of yew poisoning include: accelerated heart rate, muscle tremors, convulsions, collapse, difficulty inbreathing, circulation impairment& eventually heart failure. • Theremay be no symptoms, ifpoisoningremainsundetected, deathmayoccurwithinhours.

  27. Fatal poisoning in humans is very rare, usually if yew foliageconsumed in large quantity. • Leavesmore toxic than seeds. • One of theworld'soldestsurvivingwoodenartifacts - Clactonianyewspearhead, found in 1911 at Clacton-on-sea, in Essex, UK. • Estimatedto be about 450,000 yearsold.
