Sophora Japonica flower
Concern about the harvest of Sophora
Japonica bud and flowers
The bud of Sophora Japonica is the raw material of
Rutin and Quercetin. Every year around July in China,
it’s the season to receive the Sophora Japonica bud
and flower. But this year, because the last cold
winter and cold spring this year, the buds came 20
days later than the past. Even there isn’t new bud of
Sophora Japonica in some traditional produced
areas. Others just got very few.
It brings the uncertain factors about the price and
supplement of Rutin and Quercetin in the market,
many people concern a lot.
*******************************************
Introduction about the Sophora Japonica
Sophora Japonica called Chinese Scholar tree, or
Japanese Pagoda Tree.
The Sophora japonica is native to China and Korea,
not Japan. But it’s introduced and widely
acknowledged in Japan. It reaches 40’ to 60’ tall, is a
common urban street tree with its outstanding
ornamental features and urban hardy in many cities
in China. The tree must be at least 10-year-old to
bloom, while the cultivar “regent” blooms at six to
eight-years-old.
Sophora Japonica bud or flower, with Latin name of
Sophora Japonica L, is borne late in the growing
season, the second half of June and July in China. In
the Sophora Japonica bud, the rutin content is about
18% - 23%, and in the flower of Sophora Japonica,
the rutin content is about 8%-16%.

The harvest of Sophora Japonica buds and flowers
Presentation in 2010
1. The lowest temperature in the 50 years at Last
winter and this spring, hit Shandong, Henan,
Hebei, Shanxi provinces. The buds of Sophora
Japonica were seriously affected, it came 20
days later than before, and is reduced by 50-
60%. The price is raised to be RMB24-26, which
increased by 230% before the new buds came
out. Most of the traditional area, there’s no bud
to pick up. And others just got a few.
2. The pests seriously damaged the buds in Anhui,
Henan, Shandong provinces, it’s another reason
that causes some Sophora Japonica without bud,
other areas get it few. This affects the output,
too.
3. Some Chinese medicinal materials trading
companies and some manufacturers have
Sophora japonica buds or flowers stock,
because the abundant harvest in 2009. They got
know the bud production of this year was
seriously reduced, they hold the materials. But
the stock is not much now.
4. Cost of labor: The Sophora japonica is a kind of
big tree. It’s not easy to pick the bud or flower.
In the past years, the labor cost was not much,
farmer is not so active to take them, even the
cost of labor is growing up now.
5. Some manufacturers have imported the buds
from Vietnam through the trading companies.
But if the price goes up in China, the trading
companies will raise the price by this chance, In
the recent years, the imported bud’s price is
almost same as in china.

The End
Due to the reasons above, the Sophora Japonica
market is in the uncertain period before the
manufacturers put into production. We couldn’t
get the conclusion about the future market of
Rutin and Quercetin.
Some companies have gone to Vietnam for it. The
buds in Vietnam were coming out by June,
slightly affected by the cold weather. But the high
cost of freight and almost same price as in china,
many companies take the attitude to watch the
domestic raw material markets and the
requirements from rutin and quercetin market.
