III. Triterpenoids from Grewia Sp
III. Triterpenoids from Grewia sp. 3.1 Introduction The extract of leaves and flowers of a Grewia sp. (MG 3692) was obtained from Madagascar rainforests as a part of the ICBG program for the isolation of active anticancer agents. After testing the extract on A2780 bioassay, it exhibited activity at 3.7 μg/mL and hence it was selected for further analysis of its chemical components. The extract yielded one new and one known triterpenoid, 1 and 2. The isolation and structure determination of these compounds is described in this chapter. 3.1.1 Chemical Investigation of a Grewia sp. Grewia sp. of the Malvaceae family (previously belonging to the Tiliaceae family) is a genus of flowering plants found in tropical and temperate regions as well. The Malvaceae family has 75 genera and about 1500 species. Plants belonging to this family are economically useful, as they provide an excellent source of naturally occurring fiber, like cotton from the genus Gossypium, and certain foods like okra, from Abelmoschus esculentus, which is used as a vegetable. The stem and roots of Hibiscus tiawanensis, native to Taiwan, have anti-inflammatory and antipyretic properties.2 The dried leaf extract of Hibiscus sabdariffa acts as a anti-hypertensive by inhibition of angiotensin-converting enzyme (ACE).3 Plants of the Hibiscus sp. have been used as an antidote for chemical and wild mushroom poisoning4 as well as an Ayurvedic herbal shampoo in Indian medicine. The genus Grewia is mainly associated with triterpenoids and alkaloids. The extracts from these plants are known to have medicinal properties.5 The bark and roots of Grewia 61 tiliaefolia are used to treat skin diseases, hypertension, ulcers and diarrhoea.6 Lupenol (3.1), isolated from this plant, is known to cause apoptosis in several cancer cells.7 3.1 Lupenol Grewin (3.2) isolated from the extract of Grewia bilamellata, exhibits antimalarial activity against P. -
Grewia Tenax
Academic Sciences Asian Journal of Pharmaceutical and Clinical Research Vol 5, Suppl 3, 2012 ISSN - 0974-2441 Review Article Vol. 4, Issue 3, 2011 Grewia tenax (Frosk.) Fiori.- A TRADITIONAL MEDICINAL PLANT WITH ENORMOUS ISSNECONOMIC - 0974-2441 PROSPECTIVES NIDHI SHARMA* AND VIDYA PATNI Department of Botany, University of Rajasthan, Jaipur- 302004, Rajasthan, India.Email: [email protected] Received:11 May 2012, Revised and Accepted:25 June 2012 ABSTRACT The plant Grewia tenax (Frosk.) Fiori. belonging to the family Tiliaceae, is an example of multipurpose plant species which is the source of food, fodder, fiber, fuelwood, timber and a range of traditional medicines that cure various perilous diseases and have mild antibiotic properties. The plant preparations are used for the treatment of bone fracture and for bone strengthening and tissue healing. The fruits are used for promoting fertility in females and are considered in special diets for pregnant women and anemic children. The plant is adapted to high temperatures and dry conditions and has deep roots which stabilize sand dunes. The shrubs play effectively for rehabilitation of wastelands. The plant parts are rich in amino acids and mineral elements and contain some pharmacologically active constituents. The plant is identified in trade for its fruits. Plant is also sold as wild species of medicinal and aromatic plant and is direct or indirect source of income for the tribal people. But the prolonged seed dormancy is a typical feature and vegetative propagation is not well characterized for the plant. Micropropagation by tissue culture techniques may play an effective role for plant conservation. -

The species were characterized as zoochorous, anemochorous and autochorous. Out of 15,258 individuals, 87 % showed zoochory as a mode of dispersal, accounting for 68.1 % of the total species encountered. A test of independence between leaf habit (evergreen/deciduous) and dispersal modes showed that more than the expected number of evergreen species was zoochorous. The cumulative disturbance index (CDI) was significantly negatively correlated with zoochory (P < 0.05); on the other hand no specific trend of anemochory with disturbance was seen. The pre-monsoon period (February to May) was found to be the peak period for fruiting of around 64 % of species irrespective of their dispersal mode. -

Pemoposan Sebagai Bukti Taksonomi Beberapa Jenis Diospyros. Floribunda 5(2): 31–47. — Kita cenderung menggunakan struktur generatif untuk identifikasi tanaman, meskipun ketersediaan struktur generatif di lapangan seringkali menjadi masalah bagi praktik identifikasi tanaman yang berbuah hanya sekali dalam setahun, seperti pada Diospyros L. (Ebenaceae). Pemoposan (leaf flushing) masih jarang digunakan dan implikasi taksonominya belum pernah diperhitungkan. Penelitian ini mempelajari pemoposan dan implikasi taksonominya pada delapan jenis Diospyros di Ecopark Cibinong Science Center LIPI, Bogor (Jawa Barat). Observasi karakter morfologi dilakukan pada tiga cabang (masing-masing memiliki tiga set pemoposan dan sebuah kuncup apikal dorman) pada 22 individu Diospyros. Perkembangan kuncup Diospyros menghasilkan satu set pemoposan yang dapat dibedakan dengan set pemoposan yang sebelumnya. Pemoposan setelah periode dormansi dan adanya daun tereduksi pada beberapa spesies mengindikasikan adanya ritme pertumbuhan kuncup. Pemoposan dapat dite- mukan beberapa bulan sekali atau di sepanjang tahun dengan membutuhkan waktu 40–55 hari hingga terben- tuknya daun dewasa. Pemoposan menyediakan 39 karakter yang dapat digunakan sebagai bukti taksonomi untuk membedakan delapan jenis Diospyros berikut dengan kunci identifikasinya.

REMOTE SENSING TOOLS FOR DETECTING AND QUANTIFYING LIANAS AND TREES AT THE TROPICAL DRY FOREST by Jose Antonio Guzmán Quesada A thesis submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy Department of Earth and Atmospheric Sciences University of Alberta © Jose Antonio Guzmán Quesada, 2021 ABSTRACT Lianas are woody thick-stemmed climbers that use host trees to reach the forest canopy. Studies have shown a remarkable increase in liana abundance in the last two decades, while others have shown that liana abundance is associated with detrimental effects on forest dynamics. Liana abundance presents peaks in highly seasonal forests such as the Tropical Dry Forest (TDF); regions that are under threat for frequent droughts, fires, and anthropogenic pressures. Despite their abundance and relevance in these fragile ecosystems, there are no clear research priorities that help to conduct an efficient detection and monitoring of lianas. This dissertation aims to integrate new remote sensing perspectives to detect and quantify lianas and trees at the TDF. This was addressed using passive (Chapters 2 ‒ 4) and active remote sensing (Chapter 5). Using thermography, Chapters 2 explored the temporal variability of leaf temperature of lianas and trees at the canopy. Temperature observations were conducted in different seasons and ENSO years on lianas and trees infested and non-infested by lianas. The findings revealed that the presence of lianas on trees does not affect the temperature of exposed tree leaves; however, liana leaves tended to be warmer than tree leaves at noon. The results emphasize that lianas are an important biotic factor that can influence canopy temperature, and perhaps, its productivity. -
