Tri-calcium phosphate (TCP) and cholesterol are major constituents of human stones. Dissolution of TCP by extracts of kulfa (Portulaca oleracea), pathari (Trianthema monogyna), tomato (Lycopersicon esculantum) and grape (Vitis vinifera) has been studied by monitoring Ca content in the filtrate by flame photometer. Grape extract is found to be most effective for dissolution of TCP amongst other ...

Predictable seedling establishment is essential for resource-efficient and cost-effective crop production; it is widely accepted as a critically important trait determining yield and profitability. Seed vigour is essential to this, but its genetic basis is not understood. We used natural variation and fine mapping in the crop Brassica oleracea to show that allelic variation at three loci influe...

During the last decade, the paradigm that low toxicant doses often have stimulatory effects on plants has become widely accepted. At the same time, low toxicant doses of metal salts have been observed to inhibit the growth of the most vigorous seedlings of a population in vitro, although mean plant size has remained unaffected. We hypothesized that this kind of selective low-dose toxicity is no...

Penggunaan tanaman dalam bidang farmasi saat ini terus digalakkan. Penelitian terhadap beberapa telah dilakukan, salah satunya herba krokot (Portulaca oleracea L) yang terbukti berkhasiat antibakteri karena kandungan flavonoidnya. Handsanitizer merupakan pembersih tangan memiliki kemampuan menghambat hingga membunuh bakteri. Tujuan dari penelitian adalah untuk mengetahui efektivitas formulasi e...
